I have solved my websocket warnings “access denied” with forms on the tablesspanel.
The servoy-api (hide-form / show-form) takes some time to load or onload. In the meanwhile the client is calling method getActiveTabUrl constantly (why this much of calls I don’t know.? Because of all client/server communication with replicating browser/server state / form watchers ?). When the form is in a busy process of showing or hiding it will give “denied access” errors in the application server.
I changed the code like servoy-default-tabpanel. When a form is getting onshow or hide it put a waiting-status. When show/hide is ready the status is released. Other methods which are calling the forms on the server are checking first the waiting status and only run when the form/server is not busy with showing/hiding.
In my case I needed a reload form. When the main-template with tabless panel is the same as the previous but formstate on tabpanel changes I had problems that on the new forms the OnShow methods were not running on the server. With a ReloadForm of the main-template it is working normal. For changing the containedForm I have also made an API. I experienced that model-changes are not pushed to the client on the moment of call in the method but on the end when the server is ready with the complete method.
Andrei/Servoy: Can you check my code? I’m a little afraid that a form can get in a wait-status and gets in an endless waitingloop. Application could freeze on the client.
