Eclipse RCP: Application doesn't recognise the defined editor. (Getting PartInitException).

Question

I extended from org.eclipse.ui.editors and defined the editor-id in plugin.xml as "MyEditorId". I wrote corresponding editor class. Then I tried to open the editor from a view with this code.

page.openEditor(input, "MyEditorId");

But I am getting "PartInitException". i.e apllication is not recognising the editor by it's id. I have checked that there is no spelling mistake in the referenced editor-id. Why is editor not getting recognised?

Answer 1

Quick checks:

• Do launch your RCP application with the '-clean' option.
• check your definition of your org.eclipse.ui.editors extension (does it miss an icon definition for instance ?)
• Did you create the appropriate "dummy input" to pass to your editor ?

Answer 2

Hey, thanks VonC. I was missing the icon definition. I am able to open editor with the icon definition now.

It's kind of strange that icon is a mandatory attribute for the editor extension. It may even be left blank. Without the icon definition the editor defined never gets into the editor registry when plugin extension are read. Ain't that a little weird ?!
