Strange error in Eclipse when viewing xml files

1.7k views Asked by D.Spetz At 24 November 2024 at 23:36

I have been getting the following error in IBM RAD when opening an xml file using the XML editor:

An error has occurred. See error log for more details.
Aborted cyclic load attempt for model with id: /Example/src/com/example/resources/example-config.xml

Opening the Error Log shows multiple instances of the same error: Unhandled event loop exception

Viewing the error has the following stack trace:

I am using IBM RAD v 8.0.4.2 which uses Eclipse 3.6.2.

I am hoping that this is a simple configuration issue and that I won't need to do a re-install, since I work in a corporate environment and getting software installed/re-installed is a pain.

This error looks alike to this Bug in Eclipse

https://bugs.eclipse.org/bugs/show_bug.cgi?id=332238

It was fixed in Eclipse WTP 3.3.2, but RAD 8.0.x uses WTP 3.2.5. My advise is, if at all possible, upgrade to 8.5 at least, otherwise you will need to contact IBM Support

Hope this helps
