Error: Cannot read property '0' of null

Hi,
That’s the error that we get :
Uncaught TypeError: Cannot read property ‘0’ of null

at HTMLSelectElement.<anonymous> ((index):132)

And that’s how to reproduce it :
1)Open the following JSFiddle :
https://jsfiddle.net/vitaliest/oehj7na5/13/
2)Open the second tab in jqxTabs
3)Try to change values in the dropdown (check console)

In a few words – we have 2 jqxGrids in jqxTabs (2 tabs), and a dropdown. Every time a user changes the dropdown value we have to update data in the grid based on selected value. It throws an error. As soon as we disable filtering ( filterable: false, showfilterrow: false) it works. Any ideas how to fix it? I guess it’s a bug…

Hello VitaliyST,

This is an issue with the filterrow, so as a workaround you can disable the filter row before calling updatebounddata and the enable it again.
Also, note that it is not a good practice to use the same instance of data adapter for more the one grid.
And finally, it is better to initialize the grids in the initTab function.

I have updated your Example.

Best Regards,
Martin
