ExtendedDataTable with onselectionchange support blocking re
i think i'm having a problem with rerendering an extendedDataTable that has an <a4j:support event="onselectionchange"/> attached to it. i could be wrong about this, but i'm hoping someone can shed some light on this for me.
simply put, i have a page with two extendedDataTables on it, in a sort of "master-detail" arrangement. selecting a row (or rows) from the "master" table will display just the selected rows in the "detail" table. this is a simple enough arrangement, and it works quite well once i add the now-functional <a4j:support event="onselectionchange"/> support.
the problem i'm having occurs in my implementation of a "clear" button. basically, when i hit the "clear" button, i want to clear the contents of the "detail" table and return the "master" table to a state where nothing is selected - in effect, returning the page to the visual state when it was first loaded. i can get the "detail" table to rerender as expected, but the "master" table will not rerender.
my jsp:
<f:view>
<a4j:form id="test_form">
<h:outputText value="Master table"/>
<rich:extendedDataTable rowKeyVar="rkv"
height="140px"
width="280px"
id="master_table"
value="#{TestbedBean.masterValues}"
var="master"
sortMode="single"
selectionMode="multi"
binding="#{TestbedBean.masterTable}"
selection="#{TestbedBean.masterSelection}">
<rich:column width="60px" id="master_id_col" label="ID" sortable="true" sortBy="#{master}">
<f:facet name="header">
<h:outputText id="master_id_col_hdr_txt" styleClass="headerText" value="ID" />
</f:facet>
<h:outputText id="master_id_text" value="#{master}"/>
</rich:column>
<a4j:support id="a4j_support_master" reRender="detail_table" event="onselectionchange" />
</rich:extendedDataTable>
<br>
<h:outputText value="Detail table"/>
<rich:extendedDataTable rowKeyVar="rkv"

</f:facet>
<h:outputText id="detail_id_text" value="#{detail}" />
</rich:column>
</rich:extendedDataTable>
<a4j:commandButton id="clear_tables"
immediate="true"
value="Clear Tables"
action ="#{TestbedBean.clearTables}"
reRender="master_table,detail_table"/>
<rich:messages id="messages" ajaxRendered="true" globalOnly="true" styleClass="font_size_eight_point" errorClass="red" />
<br>
<br>
<a4j:log popup="false" level="ALL"/>
</a4j:form>
</f:view>
my backing bean:
public class TestbedBean
{
private static Logger logger = Logger.getLogger(TestbedBean.class.getName());
protected SimpleSelection masterSelection = new SimpleSelection();
protected UIDataTable masterTable;
protected SimpleSelection detailSelection = new SimpleSelection();
protected UIDataTable detailTable;
public List getMasterValues()
{
return new ArrayList<String>(Arrays.asList(new String[]{"1", "2", "3", "4", "5", "6", "7", "8", "9", "10"}));
}
public List getDetailValues()
{
ArrayList<Object> retval = new ArrayList<Object>();
Iterator<Object> iterator = masterSelection.getKeys();
while (iterator.hasNext())
{
Object key = iterator.next();
masterTable.setRowKey(key);
if (masterTable.isRowAvailable())
{
retval.add(masterTable.getRowData());
}
}
return retval;
}
public String clearTables()
{
masterSelection = new SimpleSelection();
masterTable = null;
detailSelection = new SimpleSelection();
detailTable = null;
return "";
}
public SimpleSelection getMasterSelection()
{
return masterSelection;
}
public void setMasterSelection(SimpleSelection masterSelection)
{
this.masterSelection = masterSelection;
}
public UIDataTable getMasterTable()
{
return masterTable;
}
public void setMasterTable(UIDataTable masterTable)
{
this.masterTable = masterTable;
}
public SimpleSelection getDetailSelection()
{
return detailSelection;
}
public void setDetailSelection(SimpleSelection detailSelection)
{
this.detailSelection = detailSelection;
}
public UIDataTable getDetailTable()
{
return detailTable;
}
public void setDetailTable(UIDataTable detailTable)
{
this.detailTable = detailTable;
}
}
the reason i think that this might be a bug is that the <a4j:log> reports a warning and a few errors when i click on "clear tables". here they are:
... warn[15:29:00,234]: Node for replace by response with id test_form:master_table:0 not found in document ... error[15:29:00,236]: New node for ID test_form:master_table:master_id_colmenu_menu_script is not present in response ... error[15:29:00,236]: New node for ID test_form:master_table:j_id32_menu_script is not present in response ...
i'm using a recent (october 2, i believe) nightly build of richfaces 3.3.0. any help would be much appreciated!
