I have a main table (ExtendedDataTable) where I can select a single row. Based on the selection made there I retrieve and display a List of related records from DB within a dataTable.

Everything is working fine so far, but ...

The problem starts when I want to add rows to the retrieved list. To do this I have created a

<a4j:commandButton id="showAdd" value="Add row">
 <rich:componentControl for="modalPanel" attachTo="output" operation="show" event="onclick"/>
</a4j:commandButton>

to show a modalPanel. Within that modalPanel I present a extendedDataTable containing all possible values to add (count=11500).

If I use the parameter filterValue I obtain just the filtered things to add, thats OK. But a direct input of the value I want to use for further filtering , at the corresponding input field, results no change of the displayed data. I can not add a row because I do not get the selection either.

Is there a general (filter/selection) problem when cascading an extendedDataTable in a ModalPanel?

This is the source of my modalPanel:

<rich:modalPanel id="modalPanel" minHeight="200" minWidth="450" moveable="true"
 keepVisualState="true" autosized="true">

 <f:facet name="controls">
 <h:panelGroup>
 <h:graphicImage value="/images/close.png" styleClass="hidelink" id="hidelink" />
 <rich:componentControl for="dstPanel" attachTo="hidelink" operation="hide"
 event="onclick" />
 </h:panelGroup>
 </f:facet>


 <rich:extendedDataTable value="#{myBean.editList}" var="editItem" id="editTable"
 binding="#{myBean.editTable}" selection="#{myBean.editSelection}" width="40em"
 height="50em" sortMode="multi" selectionMode="multi" rows="30" >

 <rich:column sortable="true" sortBy="#{editItem.dstnr}" filterBy="#{editItem.dstnr}"
 filterEvent="onchange" width="80px" label="Dienststellennummer" filterValue="06">
 <f:facet name="header">
 <h:outputText value="DSTNR" />
 </f:facet>
 <h:outputText value="#{editItem.dstnr}" />
 </rich:column>

 <rich:column sortable="true" sortBy="#{editItem.dstname}"
 filterBy="#{editItem.dstname}" filterEvent="onchange" width="300px"
 label="Name der Dienststelle">
 <f:facet name="header">
 <h:outputText value="Name" />
 </f:facet>
 <h:outputText value="#{editItem.dstname}" />
 </rich:column>

 <a4j:support event="onclick" ignoreDupResponses="true" requestDelay="500"
 action="#{myBean.takeEditSelection}" />
 <a4j:support event="onclick" ignoreDupResponses="true" requestDelay="500"
 action="#{myBean.takeEditSelection}" />

 </rich:extendedDataTable>
 </rich:modalPanel>
