I'm stuck while using the example snippet of the [Nesting with lazy loading], and it comes up with the error as below
Everything runs well but the detail section shows once just before the error happened and vanished at the 2nd click.
How to fix it? Thanks in advance.

The version of pqgrid applied is [ParamQuery Pro v7.5.0]
I'm preparing the jsfiddle and will tell you once I have it done.

Thanks for your replay
