Concurrent a4j requests?

[jegancareer]

Hello,
I am using functionality like search, sort and pagination in a single page.

Here
search is a4j:commandButton calls an action method.
pagination is h:selectOneMenu using valuechangelistener on change of selection box. and
sort is also a4j:commandButton calls an action method.

The problem what i am facing is whenever I switch actions between the search and then select the value from selectionbox and then do sorting.

At some point after completing the value change Listener call when i do sort then It calls the sort function and IMMEDIATELY without completing the response of sort it calls the value change listener(pagination) also - which is my previous action.

(Some times when i see the logger the output looks like they are doing parallel requests)

But this is not happening all the times. It is happening sometimes.
Please let me know what might be the problem?

My Search Button Code is below...

<a4j:commandButton value="Search" styleClass="bouton" id="btnSearch" action="#{controller.retrieve}" reRender="dataTable,pageList" oncomplete="showHideTable() />

.....
.....
.....
<h:selectOneMenu value="#{controller.page}" id="pageList" valueChangeListener="#controller.pageNumberListener}">
 <f:selectItems value="#{controller.pages}" />
 <a4j:support event="onchange" ajaxSingle="true"
 reRender="dataTable" />
</h:selectOneMenu>
......
......
......

<a4j:commandButton value="Sort" styleClass="bouton" id="btnSort" action="#{controller.sort}" reRender="dataTable,pageList" oncomplete="showHideTable() />

Thanks

check please a4j:queue component to deal with concurent requests.

[jegancareer]

Hello,
I tried using the a4j:queue in this way but same problem.

Inside the form tag i kept
<a4j:queue sizeExceededBehavior="fireNew" size="1" requestDelay="1000" ignoreDupResponses="true"/>



I need to know what might be the problem with my page having concurrent a4j calls...
and how to avoid it? because it may happen for my other screen's also


thanks,
jegan

with the queue defined you should not have concurent requests. Is the behavior fully the same after queue added?

which version you using?

[jegancareer]

Yes, There is no change. But now that problem not coming frequently.

I am using
JSF 1.2
Richfaces 3.3.0 GA

please try 3.3.1GA.. ignoreDupResponces has wrong behavior in first version and that was fixed.
