Error DbTreeView on-close webClient

We have successfully completed with satisfaction our first web solution. However, we have a persistent problem and closure of the solution given by DbTreeView as can be seen in the image.

Somebody can help us understand where it can be the mistake?

Thank you in advance

hi,

this error can be because in the method that is called on tree node click,
the tree will not be anymore on the response page.
can you detail what is in the method that is called on tree node click ?

regards,
Gabi

can you detail what is in the method that is called on tree node click ?

First of all Thanks to the rapid response. The method that runs to click is:

application.closeSolution();

In closing, however, the solution performs other activities (OnClose Method) such as redirection to a static page that informs the user to the success of log-out operation.

The static page, finally, closes itself (pop-up window in which we execute the solution).

Gabi, no further idea?

hi Giovanni,

I have tried to reproduce the issue you have, but I got no errors.
Is it possible that you create an issue in our support system for this,
and upload the solution you have so we can see what is the problem ?

regards,
Gabi
