javassist.CannotCompileException when using Tapestry

[bonsaijboss]

Hello,

I use JavaAssist indirectly in Tapestry.
In my component I have a required auto parameter with type long and I bind a long property to it. In this case I get the following exception:

org.apache.tapestry.ApplicationRuntimeException
A code generation error occured while enhancing class
example.AddressPanel.

org.apache.tapestry.enhance.CodeGenerationException

javassist.CannotCompileException
[source error] Method setObject not found in
org.apache.tapestry.IBinding
reason:javassist.CannotCompileException: [source error] Method setObject not found in org.apache.tapestry.IBinding

Stack Trace:
javassist.CtBehavior.setBody(CtBehavior.java:163)
javassist.CtMethod.setBody(CtMethod.java:311)
org.apache.tapestry.enhance.javassist.CreateAutoParameterEnhancer.createWriteMethod(CreateAutoParameterEnhancer.java:187)
...

If I change the type of this parameter from long to either java.lang.Long or int it works OK. (The bound property remained type long.)
I've tried to debug the JavaAssist code without success (I don't know it at
all).
And IBinding HAS a setObject() method!

I have deployed Tapestry very carefully to prevent any classpath errors.

Thanks for any help,
Norbi

Can you tell us the version number of
Javassist you're using?

Please write a small program to do:

System.out.println(javassist.CtClass.version);

Thanks

I have consulted with the Tapestry developers too and it seems to be a limitation in Tapestry, so I have reported it as a bug to Tapestry.

Thanks for the fast reply!
