Ajax filter on EntityQuery

[francof]

My entityquery object is a seam-gen default, so it is in Event scope.

I am trying to filter the list with an onkeyup event using 1 field set in the restriction parameters, the event works fine. However, the EntityQuery is fired twice.

When the Ajax event executes, it execute the Query twice - the first time it fires the default EJBQL and then the second time with the parameter value from the Ajax event.

I guess this is expected since the EntityQuery is in event scope.

I have seen some examples on this forum where the EntityQuery is in conversation scope, not sure why I would need that here. I tried putting my query in conversation scope but it did not change anything. Can someone give me a use case for EntityQuery in conversation scope?

my code

<h:outputText value="Filter by tax description " />&#160;&#160;
<h:inputText id="taxDescription" value="#{taxList.tax.taxDescription}"  
size="20" required="false" 
autocomplete="off" >
<a4j:support event="onkeyup" reRender="filterList" ajaxSingle="true" 
eventsQueue="taxListEvents"     ignoreDupResponses="true" 
requestDelay="1000" /> 
</h:inputText>

Thanks in advance
