[ BUILD # : 200807101204 ]
[ JDK VERSION : other ]

[JDK 1.6.0_u10 b-25]

An IllegalStateException is shown when trying to close a page, after

any exception has already been shown. Possibly, the JSF design and 
source are trying to compare the code, but since an exception was 
thrown on either of the tabs, the insync doesn't understand the 
problem. The insync should get reset as soon as an exception has 
occured on either the source or design tab.

The following IllegalStateException is thrown:

java.lang.IllegalStateException: Illegal source modification with 
dirty model C:\Users\TestUser\Documents\NetBeansProjects
