I am using dhtmlxSuite_v25_pro_91111 and I have a problem to display data in the treeGrid.
I can load the data without any problems, but when I want to click on some nodes in the treeGrid I get the errors on the screenshot.
It would be fine, if you can take a look at the attached screenshot/files.
thanks in advance
