Regarding the question I asked initially, what I did to open the case page when I open a case from the working area in the Agent Desktop section was to override the onActiveRowLogic method in the QueuePage. Then I show the code I wrote.
As when configuring a queue it is mandatory to associate a process, I created one where what I do is just read the case.
But with that, when I try to open a case for the first time in the queue, it opens the case page correctly. Now if I close and try to open the same case, it gives the following error, but the case page still opens, as it is parameterized by code.
In my case, in this queue that I'm configuring, it doesn't make sense for the process to be triggered, because what I need is just to open the case page.
That said, I would like to know if there is any way to disable the method that triggers this process. Or else another way to fix this error?
