[jbosstools-issues] [JBoss JIRA] (JBDS-3152) Cheatsheet crashes silently when they need to open files

[Snjezana Peco (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-3152?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004174#comment-13004174 ] 

Snjezana Peco commented on JBDS-3152:
-------------------------------------

The issue happens because the JBoss Perspective adds a placeholder for the Cheat Sheets view in a way incompatible with Eclipse >=4.2.
It can be reproduced in JBT when using the JBoss perspective.
It is enough to open any cheatsheet and an editor after it. 

You have to test the patch in a new workspace because resetting the JBoss Perspective doesn't help.
https://github.com/jbosstools/jbosstools-base/pull/318 fixes this issue.
