Re: [imp-dev] Problems with custom parser

[Jurgen Vinju <jurgen@xxxxxxxxx>]

Hi Anatoly,

The first thing to do is to start the ErrorLog viewer (Using
Window->Show View). The reason for the failure is (probably) logged
there. Make sure to browse through the entire stack trace to find the
original cause.

Things that might have gone wrong are:
  - you have no zero argument constructor for the class that implement
IParseController
  - the extension points to a class that does not exist
  - the language name in the parser extension is different from the
language you registered with the extension
  - ...?

Cheers,

Jurgen
