Hi,

i am trying to create and open an editor for files of type ".tcl",but
when i create a file of .tcl in the resource navigator, the editor throws
an exception which points always to the first line of the Editor class's
constructor. This Editor class is the one that extends TextEditor.
The exceptions thrown are as follows, please help

java.lang.NullPointerException

That seems to be a bug with Eclipse. Check this bug report to check if the null-pointer exception is occuring at the same place as has been mentioned in Bug-Report. Do not compare line numbers. Bug-report has a much more bigger stack.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=57367
https://bugs.eclipse.org/bugs/show_bug.cgi?id=57130

If it is same, then update your current eclipse with the latest where the things are fixed.

And I dont think it is as urgent going by the name of the editor class com.vijai.matrix.plugin.ui.Editors.TCLEditor :-)

Thanks
Venkat

Sounds like the org.eclipse.ui.editors plug-in has not been loaded
correctly - you should be seeing some other exceptions in the log
explaining why.
