Application variable problems

[mark cianciulli]

Hello, I am running cf8 on CentOS 5.2.  The framework I am using, like otheres, loads the config.xml file into the application variables.  It seems to be fine for a bit, then I start getting errors about null pointers and that the application variables don't exist.  Any one have any ideas on what the issue may be??? Thanks Mark

A couple of things....

- Does the framework have a "debug" or "development" mode setting. This
would be a setting that causes it to reinitialize everything with each
request. That's fine for development, but in production you want it to
initialize persistent stuff only once (i.e. Application variables)

- Are you using Application.cfc and if so is your application variable
loader in the onApplicationStart() function?

-If you are using appplication.cfm do you have a logic block around your set
statements that keeps them from being overwritten with each new request?
Something like...

<cfif not isDefined('appplication.somevar')>
        <cfset application.blah = "value1"/>
        <cfset application.somevar = "value2"/>
</cfif>

- Are you stuffing any complex objects into the application scope (i.e.
components)?  If you are, and if you reference return value objects from
those components in another persistent scope like "sesssion" you can end up
with unexpected errors and memory issues.

That's all I can think of...

No debug or dev setting.  I am still using the old application.cfm, and there are logic blocks in there. Basically, it looks to see if the application.framework variable exists, or if the page request does not exist.  That is what is strange, it will error out saying that the application.framework is not in the application scope.

Nothing complex about the application variables, just view and controller nodes.

btw, it worked fine on windows server.  I went through and corrected all the case-sensitive problems.

What do you mean by "if the page request does not exist"?

How are you handling the "name" of the application (as in <cfapplication
name="blah" ..>)

Ok... If it's a Linux vs. windows problem, make sure that the file is named
"Application.cfm" and not "application.cfm" (note the capital "A").

If this is the old application.cf you ran on windows is the "a" in
application upper cased like this "Application.cfm"?

This is critical on non-windows file systems.

If the page request, action=somepage, is not found in the config file, it will try to reload the xml file to see if there was a change to the file.  You will probably say that i have a case problem and it is tryin to reload the config, but i can click on the same thing, 8 times it will work, 2 times it will error.

i have the capital A, found that one out in about a minute after i tried to run it!
