Expression Editor does not work

Changed Resolution from Open to Fixed

Changed Status from New to Resolved

Hi the problem seems related to some Xtext dependency.We fixed a plugin manifest and a feature configuration. Next integration build will work fine.In the meanwhile a possible workaround is to install the Xtext SDK from the Help > Install new software.Another solution, would be to manually replace in the plugins folder of your Eclipse installation the com.jaspersoft.studio.editor.jrexpressions_6.2.0.final.jar file overwriting the old one with the updated one here: https://sourceforge.net/projects/jasperstudio/files/updatesite/6.2.0/plugins/We replaced today the files of the update site in order to silently fix the issue for upcoming 6.2.0 users. In this case please be sure to restart your Eclipse with the -clean flag.Regards,Massimo.

Thank you, this solution works fine.

Hmm...

After replacing the jrexpressions files and starting eclipse with "-clean" (which result in an error: An error occurred. See the log file null.) the problem still existed.

But then after reverting the original jrexpressions file the problem was gone!?!?

 

So for ME the problem is solved.
