paginator="true" reflow="true" paginatorPosition="top" rowExpandMode="single"
rendered="#{generalJournalEntryMB.generalJournalEntries.size() > 0}" rowIndexVar="rowIndex"
paginatorTemplate="{CurrentPageReport} {PreviousPageLink} {NextPageLink} " rowKey="#{item.id}"
selectionMode="single" selection="#{generalJournalEntryMB.generalJournalEntry}" widgetVar="datatable-list">
<p:column style="width:16px">
<p:rowToggler />
</p:column>
<p:column headerText="Id">
<h:outputText value="#{item.id}" />
</p:column>
<p:column headerText="Description">
<h:outputText value="#{item.description}" />
</p:column>
<p:column headerText="Amount">
<h:outputText value="#{item.amount}" />
</p:column>
<p:column headerText="Reference">
<h:outputText value="#{item.reference}" />
</p:column>
<p:column headerText="State">
<h:outputText value="#{item.postingState.value}" />
</p:column>
<p:rowExpansion id="expand" rendered="true">
<p:panelGrid columns="2" columnClasses="label,value" style="width:300px">
<h:outputText value="Id:" />
<h:outputText value="1" />
<h:outputText value="Year" />
<h:outputText value="1983" />
<h:outputText value="Color:" />
<h:outputText value="White" />
<h:outputText value="Price" />
<h:outputText value="#{generalJournalEntryMB.price}" />
</p:panelGrid>
</p:rowExpansion>
<p:ajax event="rowSelect" listener="#{generalJournalEntryMB.rowSelectListener}" update="main:top-menu-bar" />
<p:ajax event="rowToggle" listener="#{generalJournalEntryMB.rowToggleListener}" update="main:top-menu-bar" />
</p:dataTable>
When I expand the row without selecting the row, it show nothing. Currently what am I doing is to first select row and expand it to get desire result.
How we can trigger rowSelect even / ajax call automatically when rowToggle event fire?

You can override primefaces toggleExpansion function so it executes selectRow before
PrimeFaces.widget.DataTable.prototype.toggleExpansion = (function() {
var cached_function = PrimeFaces.widget.DataTable.prototype.toggleExpansion;
return function() {
var row = arguments[0].closest('tr');
if(this.cfg.selectionMode === 'single') {
this.unselectAllRows();
}
if(this.cfg.selectionMode){
this.selectRow(row, false);
}
var result = cached_function.apply(this, arguments);
return result;
};
})();
