Title: Remote paging updates grid every other click on next page
Post by: stevejacobsen on May 27, 2016, 03:58:37 am

When I click next page the grid updates every other click. The status bar updates and shows the correct set of records but the grid does not. In console I get:

Quote

Uncaught TypeError: Cannot read property 'call' of null (17:25:23:375 | error, javascript)  at js/paramquery-pro/pqgrid.min.js:10

On each click that does not work.

It's working fine in the demos.

you need to troubleshoot your remote server code or share a test case.
