Concurrent call to conversation problem in Seam on a sortable column

[vuntermann]

Hi everyone,

I get a concurrent call to conversation problem in Seam, when I tried to sort a column. I had many tables, so I created a generic table component.
Before to migrate my tables to the new component I had something like this:

<h:form id="formId">
    <rich:dataTable id="sdiSearchResultTable" var="record"
                value="#{sdiSearch.dataModel}" rows="#{sdiSearch.dataModel.pageSize}" width="100%" rowClasses="row1,row2" styleClass="table" reRender="sdiSearchResultTableFooter" sortMode="multi">
               
                <rich:column sortBy="#{currencySortExpression}">
                    <f:facet name="header">
                        <h:outputText value="#{messages['sdiSearch.currency']}" />
                    </f:facet>
                    <h:outputText value="#{record.currencies}" />
                </rich:column>
    </rich:dataTable>
</h:form>

And the multiple clicks on a sortable column worked well.

After the migration of the tables to the new table component, I have something like this:

a rich table
     column
           dataColumn
                   sortableDataColumn
                         rich column
                       
And the sortableDataColumn is the following:

<rich:column sortBy="#{sortByExpression}" rendered="#{column.visible}"
            styleClass="#{column.styleClass}">
        <f:facet name="header">
            <h:outputText value="#{messages[columnLabel]}" />
        </f:facet>
        <h:outputText value="#{rowData[column.property]}" converter="#{column.converter}" />
    </rich:column>

The sortByExpression indicates the property name to sort.
   
And when I tried multiple clicks on the a sortable column, then I get a call to conversation problem. I was reading http://achorniy.wordpress.com/2009/07/14/avoid-concurrent-call-to-conversation/ but these solutions seems to works on a4j:commandLink.

I also tried to change the h:form on the generic table component to a a4j:form:
<a4j:form eventsQueue="myFormQueue" requestDelay="100" ignoreDupResponses="true" />
but it did not work.

And when I tried adding a ajax support on the sortableDataColumn:
<h:outputText value="#{messages[columnLabel]}" >
    <a4j:support event="onclick" eventsQueue="instancesQueue" ignoreDupResponses="true" requestDelay="50" />
</h:outputText>
it also did not work.

Anyone know how could I solve this problem?

Thanks in advance!!

I am having this exact problem.  I see this report is a year old and noone has replied.

Does anyone have an answer to this? Vanesa did you ever figure it out?

Hi Tanya,

Try adding a4j:queue or switching global queue on.
