i'm new to ExtJs and have a problem with validating a model which i'm using for a Grid. I've already searched the web but couldn't find an answer ...
The theoretic way i'm doing it is that i define my model putting this to a data Store and that store i'm using for my grid.
In the grid i use the celleditings event edit on which i tried to retrieve the model to validate it but all i tried didn't work and Firebug always said validate() is not a function.
Anybody an idea what could be the reason for my problem?
