Can I prevent an RCP editor from loading












0















I'm loading a data-file into an RCP 3.x application. The flow typically results in the data being shown in an RCP editor.



But, if the input file is corrupt, the data cannot be loaded. In this circumstance I do not with the editor to open, by trying to cancel the PlotEditor.init() flow by throwing a PartInitException.



But, this still leaves an empty editor.



Any tips?

    The editor could close itself or display the error message with a button to do so (instead of the text area): stackoverflow.com/q/37374791/6505250

Once Eclipse is told to open the editor it will always display an editor - either the requested editor or the 'error occurred' editor. I don't know of any way to change this.



So if the data may be corrupt you need to validate it before attempting to open an editor.

I was working through the call stack, and I saw the following code. It looks like the actual UI elements start being processed at line 353. So, I thought that if I could get the method to return at line 336 or 341, then the editor UI may not get created.

  • Returning at 336 / 341 is what actually happens - handlePartInitException causes the Error Editor to display instead.
