Hi there,

I have encountered a problem when attempting to debug a jsp/javascript page
in the Web2.0 browser.

When the browser opens on the JSP page, an error dialog pops up with the message:

"An error has occured, see error log for more details"

In addition to this, a number of 'blank' messages appears in the Javascript console.

When I ran a search based on the logs, I found a possible solution in this forum, i.e.
running with the -clean option.

When I tried this the number of errors DID reduce to one, but one is enough to stop
me :)

The remaining error in the logs is:

!ENTRY org.eclipse.jface 4 2 2006-10-11 11:48:58.866
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface".

I haven't been able to find a way to get rid of this. Any suggestions?

Many thanks,

John,

John,
Would you be able to install a clean version of Eclipse 3.2 SDK and MyEclipse 5.0.1 to new directories and test the same debugging scenario over to see if the bug still occurs? The AJAX tools have been a huge focus for us since they were introduced in version 4 and each release includes quite a number of bug fixes and enhancements. So before we trail down a really long path of trial and error only to find out it was a bug that was fixed in a later release, I'd rather try that first.

If you do have a chance to do this, please use new directories for both Eclipse and MyEclipse and possibly a new workspace so you don't change any of your old install until we are ready.
