Hi
I'm trying to use filtering and sorting in the data table column header. To suppress the sorting when clicking inside the filter field I use the prototype Event.stop() method. But that yields to the problem that the calendar is sometimes blocked and cannot be opened until I refresh the complete page.
Are there solutions which work?

<rich:column filterMethod="#{invoice.filterByDocumentDate}" sortBy="#{item.bo.belegdatum}">
<f:facet name="header">
<a4j:outputPanel layout="none">
<h:outputText value="#{I18nBean['1.202']}" />

<rich:calendar id="docDate"
onclick="Event.stop(event);"
value="#{invoice.filterDocumentDate}"
locale="#{invoice.locale}"
datePattern="#{invoice.datePattern}"
timeZone="#{invoice.timezone}"
reRender="invoice_table_panel,invoice_table_pager"
ajaxSingle="true"
onchanged="this.form.submit()"
inputStyle="width:70px;" />
</a4j:outputPanel>
</f:facet>
<h:outputText value="#{item.bo.belegdatum}">
<f:convertDateTime locale="#{invoice.locale}" timeZone="#{invoice.timezone}" type="both" />
</h:outputText>
</rich:column>
