Dear All

There are three Plug-ins available

PayPal plug-in

ShoppingCart plug-in(using internally PayPal)

I am designing a membership registration and would like to use member pay by using PayPal.

Appreciate some inputs which one would be the best to pay?

hibernate events and transactions

2009-11-26T13:57:01Z

Hi folks!

I tried to use hibernate event handlers in domain classes, and it looks like it is not possible to create transactions in these handlers.
for instance, when I run transaction in "beforeUpdate" handler, I receive the following error:

ERROR GrailsExceptionResolver: Object of class [domain.Customer] with identifier [1]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [domain.Customer#1]
org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Object of class [domain.Customer] with identifier [1]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [domain.Customer#1]

Have you ever seen such problem?

I do not update any object in that transaction - it is empty closure, like Customer.withTransaction { }

Thanks for any help!

Regards,
Sergey

Searchable Plugin: search subset of domain objects

2009-11-26T13:35:14Z

Hi,

I have an Order class that I would like to search with the Searchable plugin. However, I don't want to search all the instances of Order, just a subset of them. Something like this:

List<Order> searchableOrders = Customer.findAllByName("Bob").orders

// Now search only these orders with the searchable plugin - something like
searchableOrders.search("name: foo")

In reality the relational query to get the searchableOrders is more complex than this, so I can't do the entire query (relational + compass) in compass alone.

Thanks,
Paolo

Re: groovy: sorting files.

2009-11-26T12:31:54Z

You could do something like this, it would be better implemeting using regex, it's easy, but as I'm a groovy begginer and I'm pretty sure there's a better groovy way, I'm just writing the easier one.

a = a[9..12] + a[7..8] + a[5..6]

b = b[9..12] + b[7..8] + b[5..6]

return a <=> b

Re: Why are the gsp views inside the production war ?

2009-11-26T10:43:45Z

They are compiled only on the first time the page is actually accessed. So the source needs to be somewhere. But I think Graeme was working on precompiling them

Problems with return/render

2009-11-26T10:13:33Z

here is the code of the controller:
def nome_var = params.nomevar
println "the variable is: ${nome_var}" //it works
render(view:'show',model:[teacherInstance: teacherInstance, subjteach: varlist, subjname: varname, vargiangio:nome_var])

Once in the GSP if I print ${subjteach} it gives me the values,if I print ${vargiangio} it gives me nothing!!
params.nomevar comes from the params map of a g:remoteLink
<g:remoteLink controller="teacher" action="show" id="${teacherInstance.id}" params="'nomevar=${found2.id}'">

Why??

Gorm Standalone not working.

2009-11-26T09:59:45Z

Hi all,

I've been trying to get Gorm working without Grails, following instructions at:
http://grails.org/GORM+-+StandAlone+Gorm

I've come across 2 problems.
1. I can't seem to download the zip distributable on the Grails website. This is following the link:
http://www.grails.org/%5Egorm-0.5.6.zip

After trolling the web for a mirror, I finally stumbled upon the codehaus site with a similar (working) page and downloaded the zip:
http://docs.codehaus.org/display/GRAILS/GORM+-+StandAlone+Gorm
Is this the correct zip that I should be using?

2. The next hurdle was to get the most basic test working. I followed the instructions, and on running the ant command line, I get the exception listed below. The problem seems to be related to the hibernate.dialect property not being picked up in the hibernate.properties. Here is the hibernate.properties that I used.

Hope someone can help,
Thanks,
Marco.

Form post in webflow

2009-11-26T08:51:55Z

Hi All,

I am seeing a strange behavior when making a form post in a webflow. I am using 1.2-M4. Below is one of my webflow view state pages:

<g:form controller="account' action="register" method="post">

...

<g:submitButton name="next" value="Next"/>

</g:form>

When I click the next button, all of form input parameters are rendered in the URL query string as if the form is executed as a GET method. This is a big problem because I use webflow for account registration. In this case, it renders the password value in the query string. The only way to get around this is to call "params.clear()" in each webflow action closure.

Has anyone seen this problem? I searched the mailing list and JIRA but couldn't find any posts related to this.

Thanks!

Kenny

Re: Changing quartz job timeout property

2009-11-26T08:42:33Z

Hey,

You can try something like:

CronTrigger trigger = quartzScheduler.getTrigger("name","group")
trigger.setCronExpression("0 16 16 * * ?")
quartzScheduler.rescheduleJob(trigger.getName(), trigger.getGroup(), trigger)

or just define a new trigger (TiggerUtils is handy) and do:

quartzScheduler.rescheduleJob("old trigger name","new trigger group",newTrigger)

Here is the api which is handy for things like this:

Quartz : Scheduling Closure "as" Job Error

Hello Grails people, hope you are all having a fine day!

I am trying to schedule a Quartz job as per page 356 of the Definitive Guide To Grails V2. Here's my code:

Job job = {
println "Job Running!"
} as org.quartz.Job

JobDetail jobDetail = new JobDetail("dailyReports", "reportJobs", job)//error here
quartzScheduler.addJob(jobDetail, true)

When I try to create the JobDetail instance i get the following error :( :

Re: Re[grails-user] running application after change in a service, a must?

2009-11-26T04:10:35Z

Thanks Robert.
I do need the transaction attribute, because most of my services handle database operations.
Do you know of any other way to improve my development experience with grails?

If you don't need transactional semantics for that service you can
set:

static transactional = false

and then reloading will work.

How do I disable a gui:datePicker from user input? I want the entire component o be disabled. Not only the input text field.

Rerunning application after change in a service, a must?

2009-11-26T03:47:27Z

Hi all,

I rely on service objects. I think that since domain object replace the use for a DAO, they should be at-least accessed from a service for re-used functionality.
So, I change services all the time (and restrict contorllers and views for routing and presentation logic).
I see that I need to restart the app each time I make even the smallest service (not even chnages to method signatures). Otherwise, Spring is angry about not find beans and other problems.

Is it me?, Is it Grails?, Is this style of encapsulation that rare here?

Please help,
Thanks.

Re: Custom BaseController

2009-11-26T03:23:16Z

Hy Fred,

that looks exactely like what I want.
Could you please post the code for the instance service whicht injects
the crucial class into each controller?

That would be great.

RE: Increasing version number without save or update

2009-11-26T03:22:57Z

You are my hero ;)

So the problem was really triggered through a custom setter of a collection.
In my domain class I have changed or casted the collection to a java.List and than I have called that in a normal grails manner domain.collection and work on it.

The solution was to remove the cast in the domain class and than it works, without increasing version number.

Thanks for the hint Burt!

But it would be really nice if you can set a custom setter for a collection in grails without increasing version. Because now I can not access an element in a collection, cause the java.Set does not support indices.

Mike

Burt Beckwith wrote:

Every get() call bumps the version? That's unusual. One thing that will unexpectedly increase the version of an object is changing a child collection. I guess Hibernate is considering a collection add or delete to be changing the "property".

I saw something like this in a regular Hibernate project. I had a custom setter method that copied the contents of a mapped collection into a new one, and although the contents didn't change, it went from being a PersistentList to an ArrayList and Hibernate deleted every child and then re-added them. The net effect was no data change other than a version bump, and a lot of unnecessary database thrashing.

Do you have any custom setters or getters for a collection?

Burt

----------

Hello,

my problem is that on each request the version number of an object of a
domain class is increased without that the object is changed. So the object
is not been saved or updated, but the version number is increased.

My understanding of the version attribute is that hibernate use this version
for checking whether an object was changed while I'm using it. And therefore
the version is only increased, if the object is saved or updated. Is that
correct?, or is that version attribute also increased for other reasons.

I found one thread
(http://old.nabble.com/increasing-version-number-ts24364659r0.html) where
the author had the same problem and one solution was that this problem was a
grails problem and it was fixed in version 1.0.5. But I use grails 1.1.1 and
the problem is still there.

Has anybody the same problem and a fix for it?

Thanks,
Mike

SOLVED - Dojo remotefunction content parameter missing

2009-11-26T03:14:29Z

Hi, I don't know if this is the best place for posting such a thing (I guess not, but I'm not able to find it in jira, my apologies in advance), but I've found a workaround for a bug in dojo ajax calls.

The remotefunction call misses a content parameter that holds a map of key:value pairs that are the actual parameters of the ajax call itself. Passing them in the params map leads to modify the url parameter instead, calling the grails action with a hard-coded string: passing values like this.value is not possible.

Having params map for url parameters and content map for action parameters is a better approach and run-time values are correctly parsed.

Attached to this message id the patched DojoProvider.groovy

Hi,

did you manage to solve the problem?
I have the same issue. Directories are all writable. Sometimes the application starts without any problem, but mostly it gives me the same error.

Greetings,

Finn, Patrick

I am running into the same error with Grails 1.1.1, Searchable 0.5.5 and tomcat 6. How did you get around this error? I am running into this both in WinXP and Linux machines. In windows, I have moved my compass index location to /tmp where it does not have any permission issues. But tomcat still fails to come up.

On a barebone application that has one domain class and the searchable plugin, I donot have any problems.

Command object in service

2009-11-26T02:23:44Z

Is there any way to inject "magic methods" (validate, hasErrors ...) to the command object on the level of service?

Re: Custom BaseController

2009-11-26T02:19:17Z

My controllers and services are now generic, see my post on this list Oct 16:

Since the post I added a feature for supporting command objects that seems to work well in my current project.
