Build Identifier: 20100617-1415 I created an enum called 'bar_t'. Then I created a static function foo, returning a bar_t. When I tried to set the return type, I typed 'bar' and pressed Ctrl+Space, but the popup said that nothing was found, and the status bar at the bottom said "java.lang.ArrayIndexOutOfBoundsException: 0". Reproducible: Always Steps to Reproduce: See above
Created attachment 172694 [details] Screenshot of the problem
I cannot reproduce the problem with the following code: typedef enum {a, b, c,} rid_data_status_t; static rid Please provide the following things: * The stack-trace for the exception if it can be found in the log-file * A sample source file with which you can reproduce the issue. * A parser log for the file (context menu of file in project explorer - Index - Create Parser Log File)

Pretty obvious bug in org.eclipse.mylyn.internal.cdt.ui.contentassist.DOMCompletionProposalComputer
Hi Nathan, I was unable to actually reproduce the problem, but found the the cause of this problem. I will backport this change to Mylyn 3.4.1 so that other users do not run into this problem. I will let you know when the build is available to confirm.
This has now been backported to the Mylyn 3.4.1 branch.
I don't see it showing up as an available update. Is there something I need to do to get this fix?
Hi Nathan, We haven't released a weekly update with this fix yet to my knowledege and I can let you know when it is available.
I have published an updated build that is now available from the maintenance update site: http://download.eclipse.org/tools/mylyn/update/maintenance . Please let us know if that resolves the described problem.
I do not observe the problem any more. Thanks! Nathan
