TypeError when attempting validation on dhxGrid

I’ve created a number of validations for columns within the grid I’m working on. When trying to test the validations, I periodically get the following error in the console:

Uncaught TypeError: Property ‘isnull’ of object # is not a function dhtmlxgrid_validation.js:12

This happens when I clear out a cell and move from one cell to another, even though part of my validation for each cell is that the cell in not empty. So in this case, I expect a validation error, but I’m not sure why I’m getting the TypeError mentioned above.

Any ideas?


Please, provide any kind of sample of your init code to reconstructed the issue

Here’s a copy of the code I’m working with.

Just ignore the non-javascript stuff at the top. The whole file gets processed through ruby first and those values get populated. End result is plain old javascript.



Unfortunately the issue still cannot be reconstructed locally.
Please, provide a complete demo where the issue can be reproduced.
Here is the tutorial about creating a demo:
