Error Activate of window '10025' refused because there are active modal dialogs

Hi, I'm making a mod of the confluence skin, with the custom search using skin shortcuts. When I select the item, kodi makes a selection noise but doesn't respond in any way. Reviewing the logs, I have seen that it gives me the following error:

"Activate of window '10025' refused because there are active modal dialogs"

How could I solve it, and if you could tell me if I have to put some part of my code, I would appreciate it.

Thank you
