decreaseIndentPattern has no effect

Question

I am trying to create a TextMate bundle for a new language but am having issues with the decreaseIndentPattern. It seems to have no effect whatsoever, even with a trivial example:

increaseIndentPattern = 'start';
decreaseIndentPattern = 'end';

I have set the scope correctly and the other settings in the same file do work (including the increaseIndentPattern). Am I missing something?

Answer 1

Found out that to enable indentation correction on text based files (my scope starts with text), the following is also required:

disableIndentCorrections = :false;
