Struts2 plug-in fails with custom type converters

[GoogleCodeExporter]

I'm running into a problem whereby the Guice/Struts2 plug-in fails to 
initialize properly when there are custom type converters defined in 
xwork-conversion.properties.

The problem appears to be that Struts2 initializes type converters before 
interceptors (this is done in XWorkConverter). Without the type converters 
defined, buildInterceptor is called first for each interceptor, so that when 
buildBean is finally called it properly creates the child injector. With type 
converters, buildBean is called prior to the calls to buildInterceptor, 
creating the child injector without the interceptors registered and resulting 
in a NullPointerException when attempting to invoke an action.

I have created a small test app that shows this problem. Running the app should 
illustrate the problem as soon as you attempt to invoke the action called 
"test". If you comment out the entry in xwork-conversion.properties, the app 
runs as expected.

I'm running the test app under Tomcat 6.

Re-attaching the file. The original was unnecessarily large due to not deleting 
the target directory before zipping.

Can you test this out with 3.0rc2?  It contains some changes to the struts2 
plugin.

Hi, sberlin: This was tested with 3.0rc2 (both guice and the struts2 plug-in).
