1. Hello,

   Skuid Version: 13.0.11

   Model that is used for style condition, if the data for that model is changed/edited then an error will be produced. (The XML for a page bellow is set up to reproduce the problem).

If there are 2 conditions, where one of the conditions is in context and other one is not, if the condition without context is before the condition with context then the 2nd condition will lose context. (Not reproduced in the example below).

Best,

Lukas
