Hi all, i'm using ZK framework (ver.8.0.2) to build a web application and i encounter a strange behaviour inside zk.wpd file. I'm using a publish/subscribe event queue to build an asynchronous task running in background: it works all fine until i call EventQueues.remove(queuename, EventQueues.DESKTOP)) method. After the queue is destroyed, Zk start an infinite loop in zk.wpd file, resulting in a series of undefined ajax requests (see the file attached) Can anyone explain me how to fix this behaviour? Thank in advance

series of undefined ajax requests

usually these 'undefined' requests contain a payload which you can see after clicking it and checking the request parameters (in chrome dev tools at the bottom of the 'headers tab')

Did you try using a more recent ZK version, maybe the issue has been fixed already.

Otherwise please provide the exact code leading to the problem, so that someone can try it out, and suggest what to change.

Hi, thanks for your answer. Checking the requests by devtools i've seen that until EventQueue is working the payload is like this {"rs":[],"rid":788}. When i clean the EventQueue the payload change as here: {"rs":[]}. Due to project requirements for now, i cannot update ZK version

independent of your project requirements, you can still try running that part of your application using a higher ZK version, just to check if there is any version above your's that fixes the problem. If yes then you are one step closer to patching the problem.

If you can't perform these tests for technical reasons, then it will help if you can isolate a simplified version of your code reproducing the issue so that anyone in this forum can have a look and potentially help.
