[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-7328) Renaming smooks xml configuration file extension can cause errors

[Max Andersen (JIRA)]

    [ https://jira.jboss.org/browse/JBIDE-7328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559933#action_12559933 ] 

Max Andersen commented on JBIDE-7328:
-------------------------------------

only workaround I can think of is to install a resource change listener and if a file is being renamed that is open in a subclass of the structuredtexteditor we should offer closing the editor (after possible save) and reopen it again..

Note: this sounds like not just affecting smooks but anything "xml" releated.
