Re: Can't find samples

2009-09-30T08:58:29Z

Looks like you either haven't built or you have removed SampleApplication.java. Typically you get that exception when the JVM can't find a class because it is not among the defined dependencies, or that it is not in your source-tree.

Re: Can't find samples

Hi, a couple of hints on the samples code:
The table pages won't work at all, as the table generation has been ripped out (it never worked very well, and was quite restrictive and unflexible in what it did).

As for the update-forms, these will be broken, as the JPA package has been reworked to be more scalable/performant.
The best approach here is probably to compose a org.wicketrad.jpa.UpdateBeanDataForm (in the wicket-jpa module) with a org.wicketrad.propertyeditor.form.BeanPanelForm ("Horizontal" or "vertical" layout implementation in wicket-rad-core).

Hi,
I'm afraid I have been busy with other things, so the documentation/sample maintenance has fallen off a little..
However If you download the latest release from sourceforge, I believe the samples should still be around in that.
You might need to fiddle around a little with the code though, as a lot has changed.

Shane Hayes wrote:

I'm new to java/wicket and like what I read about wicketrad. I can't find the samples referenced and those would really be helpful. Especially if there was a simple parent child structure like Company and Orders.

Did this move or is there another example of how to use wicketrad?

I was able to download the latest code, but there are no examples in that structure.

Re: Sourceforge m2 repo is down

2009-09-13T15:19:26Z

Hi,
The Jazzy Plugin is retrieved from a separate repo (not the Wicket RAD) repo. However, it seems to have moved.

I haven't cut a new version of Wicket RAD in a while, but the trunk code in Subversion (at https://wicket-rad.svn.sourceforge.net/svnroot/wicket-rad/trunk ) is stable and should have this problem sorted, so in the short term, my recommendation would be to do a checkout on it and build from that (it is likely that the next release will be cut from that very revision number that is there now).
The only thing that has changed considerably from the 0.6 version is that the table generation has been removed, as this never worked particularly well in terms of flexibility.

Re: Whats 0.8 about?

2009-07-18T08:35:09Z

I know, working in details of a project is kinda flow...

BUT

I've learned (when doing business in a company) that marketing is often underestimated. So, take a small time, sit down, take a free brain (not between two deadlines, maybe on a rainy saturday afternoon) and think about your ambitions.
Then write it down in your Roadmap.
Everyone's watching this project (like me, maybe taking it for crud components in our company) can see that this one is not dead. Wicket 1.4 is hot and it's a real feature to support it yet (databinder: 1.3.5).

This is a little tip from what I've learned when fighting against the evils of Struts/JSF with my double wicket light saber.

Re: Whats 0.8 about?

2009-07-18T04:18:10Z

Hi,
I have been really poor at updating the roadmap, mostly because it has been in flux.

0.8 in svn is usable (wicket-jpa and wicket-rad-core projects), though the table component has been entirely removed, as I was somewhat unhappy with it (table components are notoriously hard to get right, and I didn't). The Wicket JPA package is a much improved version of the Open Session In View pattern, which is simplified and more scalable, it doesn't open a connection unless it needs to.

Also, everything is running of Wicket 1.4 now.

Re: Sourceforge m2 repo is down

2009-06-02T16:13:16Z

Hi,
I checked source forge, and the repo is all still there. However I believe there is two problems, one a minor annoyance but non issue, the other one potentially requiring a bit of work:
- Sourceforge disallows directory listing on their web servers, you can't actually check the repo, but if you put the dependency correctly in your pom.xml it should all come down as it should.

- there is a potentially broken transient dependency due to other repos moving regarding a spellchecker for the Wysiwyg editor provided.
The crude, blunt force temporary fix for this is to remove the dependency to the wicket-contrib-tinymce package altogether if you do not use it, and fix the 2 or 3 compilation issues that result (basically deleting the sources).

The new release has taken a while as I have been busy on other things, and the future direction has had to gestate a while in my mind, but I am going to release a Wicket 1.4 compatible version soonish (it's already available in SVN).

Re: Sourceforge m2 repo is down

2009-06-02T05:13:53Z

Hi,
I will check this this evening - however in the meantime if you are trying to folder browse, the issue might be that Sourceforge disallow folder browsing and only allow direct access to files (ie the artifacts).

I wil try to roll out a new version in the interim tonight (updated for Wicket 1.4) with fixes for some of the transient dependencies.

Re: Wicket-RAD 0.6 with Wicket 1.4-SNAPSHOT

Hi,
If you don't mind getting your hands dirty, the easiest way is probably downloading trunk from SVN (instructions exist on the wiki: http://sites.google.com/site/wicketrad ), then searching for "org.apache.wicket" in the pom.xml files and updating it to the 1.4 version you want to use.

After this, you should be able to just run "mvn clean install eclipse:clean eclipse:eclipse" to get everything generated for you.
It is possible that some changes have broken, so you might have to fix/ignore some tests and compilation issues, but I would expect the problems to be minimal.

As for the difference between the last release and trunk: not much really, mostly just a few bug fixes, I will try to upgrade to 1.4 soon, but I haven't had time yet.

My projects pom.xml has dependencies on junit, wicket-rad-jpa, wicket-rad-core, and hsqldb. That's it. If I check the project settings 'Java Build Path', I see that wicket-1.3.5 is being used.

I fear that if I add *additional* dependencies on wicket-1.4-SNAPSHOT, this will result in a complete chaos as Wicket-RAD will continue to use/reference wicket-1.3.5 while my code is referencing 1.4. Right?

Wicket RAD Maven Archetype

2009-01-02T06:35:00Z

Hi all,

To help new Wicket-RAD users getting started with Wicket-RAD as easily as possible, I have created a Maven Archetype for Wicket-RAD. The archetype lets users, within a few minutes, generate a fully working Maven based web application with basic CRUD functionality (using an in-memory HSQLDB database).

To learn more visit the homepage of the archetype : http://code.google.com/p/wicketrad-archetype/

My related blog post can be found at: http://codehaven.blogspot.com/2009/01/wicket-rad-maven-archetype.html/

I am very happy if anybody have comments, questions or suggestions. If so please post them here!

Re: Misc Thoughts

2008-12-30T03:11:17Z

Hi,

> As for point 3, could you please elaborate a little?

Yes, it is just a cosmetic point. So, instead
@Sortable
@TextField
@Order(1)

it wouldn't blow up the code if you use a one-liner:
@WRAD(sortable="true", editor="textfield", order="1")

for the order problem you could add an annotation for the whole entity:
@WRAD(prop1, prop2, prop3)
but this is not refactoring-save

Another cool point would be the tab feature in WicketWebBeans: it sorts the properties of one bean
into several categories (tabs). E.g. a general property tab and a specific property tab. See here:
http://wicketwebbeans.sourceforge.net/wiki-html/Tabs.html

Regards,
Peter.

Re: Misc Thoughts

2008-12-29T16:41:31Z

Hi,
Thanks for the feedback!

It is entirely possible to implement custom behaviours and ways of configuring the forms by implementing the IFormMetadata interface, and it's dependent interfaces. You could effectively implement any behaviour, or any data source (not only beans, I have thought about db tables).
I think this is the answer for points 1 and 2.

At the moment I have not gotten around to implementing any other configuration options than annotations, and I think they work quite well as they are very explicit in what they do.
But if you want, I can gladly look at including other ways of configuring forms and behaviours if you have ideas that you want to use. I'm more than happy to look at contributions.

As for point 3, could you please elaborate a little? I don't quite understand what you mean. Although I'd be very happy to get rid of the @Order(1) way of ordering fields if I could think of a more elegant solution.

4 - There is no direct way of avoiding DataWebApplication, however if you want to extend something else, it should be simple to just look at the DataWebApplication implementation and put that into your WebApplication implementation.
All it really does is override the newRequestCycle() method and provide the DataRequestCycle for each RequestCycle instead of the default one.

Re: ClassCastException in 0.6

That could potentially be the case - last time I used m2eclipse it was way too brittle and undependable, so I canned it.. Maven itself has a lot of classpath issues, and m2eclipse tends to aggrevate them by mixing it with the Eclipse classpath..

The one thing that does throw me off a little is the reference to the class org.hibernate.search.event.FullTextIndexEventListener , as Hibernate Search is not a dependency of the sample application to my recollection. Is it possible that you are running and/or have changed the config in some way, so that there may be conflicting configurations and/or dependencies or something to that effect?
