Need Help :: <a4j:queue /> Not working as expected

[sunay]

Hello All,

Please Help me out, I have one extended data table and it is sending concurrent request, so i have put it inside the <a4j:queue> tag but when i am tracing i can find that the request is not queued up but it is concurrently calling my code and due to that creates some problem. I stuck here with the problem of concurrency . below is my code.

Thanks in Advance.

queue defined in a wrong way. check documentation.

[sunay]

After defining the queue in right manner as in documentation still it sends multiple request and my table is not updated some time.

[cremersstijn]

try this: <a4j:queue size="1" ignoreDupResponses="true" />

[sunay]

i have already tried this , my problem is my grid is not able to update its view because before second response is comming first respose renders the view and not update, again i click browser's refresh button it gives correct data.

[ilya_shaikovsky]

you defined name of the queue - please remove it - so it will became default for this form and will handle all the requests.

[sunay]

<a4j:queue size="1"/>

i have tried with this statement as well still not working, my datatable is not able to update its view some time

[sunay]

I can see my header changing but data is not able to change
