Re: NPE for category option combos

  Thread Previous • Date Previous • • Thread Next 
Hi Lorill,

I have made a fix for this now in 2.21 and trunk.

The crash happened because the option combo must have a category combo. In
any case, it could be that you plan to set this later and it should not
crash at that point.

regards,

Lars
