Hi,
When I call $(...).dialog in the page where pqgrid is loaded, it is not showing the dialog buttons. The same code works on every other page of our program.
Our project is using jQuery UI - v1.11.4 and I see that your project is using v1.12.1 However, updating in out project didn't help (and actually broke other things since they need to be migrated. - however the modal did work on other pages even after updating the library to be 1.12.1, so it seems that it isn't based on a dependancy issue.)
1. Working (rest of project)
2. Not working
