Description Andreas Steinwachs CLA 2010-08-04 06:49:55 EDT 
Build Identifier: Bundle-Version: 2.0.1.v20100213-r6600 on GlassFish v3.0.1

First of all, I'm pretty sure that this issue is related to Bug 312132 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=312132). However I thought that it was better to open a separate entry in order to not introduce confusion as this one leads to a different exception.

I'm using GlassFish v3.0.1.

The exception:

javax.faces.el.EvaluationException: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long

This exception appears when calling entity.getId() when getId() is a public method of a generic MappedSuperclass that returns a generic IdType.

Please refer to the files attached for more information.

Reproducible: Always

Steps to Reproduce:
Please see the attached files stacktrace.txt and testcase.txt for a description on how to reproduce the issue.

Changed the headline as it doesn't really matter if there's a one to one relationship involved, it's rather the generic mapped super class id that seems to be the problem.
Comment 5 Guy Pelletier CLA 2010-08-16 14:35:30 EDT 
I was unable to reproduce this error off the 2.2 stream.

I was able to reproduce it off the 2.1.1 stream however.

Therefore, I suspect the following bug fix corrected this issue as well, BUG 312132

Thanks Guy, I have tried the 2.2 stream and it seems to work so far, but as I ran into a couple of other issues I will have to reconfirm later.
Comment 7 Andreas Steinwachs CLA 2010-09-15 14:20:14 EDT 
Well, so far this issue seems to be resolved in deed. May be closed in my opinion.
Comment 8 Guy Pelletier CLA 2010-09-15 14:28:11 EDT 
Fixed in the latest streams.
