We are using the Coldspring generated remote facades and are getting strange
results. They appear to work fine when called from a .CFM page directly, but
when we call them from Flex using the RemoteObject, we get an error. The .SWF
is running inside a .CFM page.
I have seen in the coldspring mail archive, some discussion about strange
behavior when calling from flex, but could not find a fix
-------------- QUESTION
----------------------------------------------------------------------------------------------------------------------------
Has anyone seen this behavior or had success correcting it? It almost seems as
if the remoting call cannot find the application scope and the coldspring
components inside the application scope.
--------------------- BACKGROUND
---------------------------------------------------------------------------------------------
Steps to de-bug thusfar are as follows:
1) original message displayed to the client:
Sorry, a ColdSpring BeanFactory named serviceFactory was not found in
application scope. Please make sure your bean factory is properly loaded.
Perhapse your main application is not running?
2) I notice that this message is returned by the coldspring generated remote
façade, so I removed the cftry/cfcatch stements from the generated façade. The
next error that comes back is: "Could not find the ColdFusion Component
coldspring.beans.util.BeanFactoryUtils."
3) When I run the code that is inside the generated façade from a test.cfm as
seen below, the test page works fine (note "var" remved from cfset beacause not
inside a function).
<cfset variables.beanFactoryName = "serviceFactory" />
<cfset variables.beanFactoryScope = "" />
<cfset bfUtils = 0 />
<cfset bf = 0 />
<!--- make sure scope is setup (could have been set to '',
meaning application, default) --->
<cfif not len(variables.beanFactoryScope)>
<cfset variables.beanFactoryScope = 'application' />
</cfif>
<cfset bfUtils =
createObject("component","coldspring.beans.util.BeanFactoryUtils").init()/>
<cfif not len(variables.beanFactoryName)>
<cfset bf =
bfUtils.getDefaultFactory(variables.beanFactoryScope) />
<cfelse>
<cfset bf =
bfUtils.getNamedFactory(variables.beanFactoryScope, variables.beanFactoryName)
/>
</cfif>
<cfset remoteFactory =
bf.getBean("&CompanyService_remote") />
<cfdump var="#remoteFactory#">
---------------------- CODE BELOW
----------------------------------------------------------------------------------------------------------------------
This is our RemoteObject call:
<mx:RemoteObject id="RemoteCompanyService" destination="SecureColdFusion"
showBusyCursor="true"
source="remote.RemoteCompanyService">
<mx:method name="getCompany"/>
<mx:method name="getCompanys"/>
<mx:method name="saveCompany"/>
<mx:method name="deleteCompany"/>
</mx:RemoteObject>
This is the remote façade generated by Coldspring (with cftry and cfcatch
removed from the setup method for de-bugging)

Revision 1.5 2006/06/25 13:22:43 rossd
removing debug code
Revision 1.4 2006/04/04 03:51:27 simb
removed duplicate local var bfUtils
Revision 1.3 2006/01/28 21:44:13 scottc
Another slight tweek, everything refers to beanFactory, not context
Revision 1.2 2006/01/28 21:39:57 scottc
Shoot, the RemoteProxyBean was looking for an applicationContext instead of a
bean factory. Updated to look for a beanFactory, but I
need to test!
