Well, if one writes JavaScript applications etc. like with Objective-J  
it is useful to have the chance to have a look at the errors more or  
less automatically, meaning the error message pops up or whatever.
With Obj-J I found a way to redirect all these errors to a file and  
start 'mate theFile'.
Also to wrap all the JS stuff into try catch(e){TextMate.system} works

This is in some sense tricky. Sometimes I see:
25.09.08 09:29:03 TextMate[116] JavaScript Exception: 22:  
ReferenceError: Can't find variable: objj_imp1ort

but also:
25.09.08 09:26:10 TextMate[116] JavaScript Exception: 1208: undefined

whereas the Web Inspector shows:
Can't find variable: CPAWindow

Anyway, thanks for the hints. For Obj-J I found a way.
