PrimeFaces, can’t update tab disabled attribute - jsf

Question

I need to update a tab’s disabled attribute when a user edits a dataTable using rowEditor.
I have a ajax tag in a dataTable listening for event="rowEdit" which calls a backing bean method that sets the tab's disabled attribute to true.
If I reference only the tab group with the tabView id as in update=”:tabView” the tab will update but only the edited row of the dataTable renders with no grid lines. If I reference the tab as in update=”:tabView:tab” IDs, the dataTable renders fine but the tab’s disabled attribute doesn't.
The tab being updated is not in the same tab as the dataTable being edited.
The dataTable is in the rates tab and he tab I'm trying to update is tbVSelRates

Hope this posts right, first time posting a question on StackOverflow
Thanks
public void applyRowChangesMassUpdate(RowEditEvent event){
DataTable dtRates = (DataTable) event.getSource();
Product dtRow = (Product)dtRates.getRowData();
logger.log(Level.FINE, "Molecule: {0}", dtRow.getMolecule());
logger.log(Level.FINE, "Projected Sales: {0}", dtRow.getYtdProjectedSales());
logger.log(Level.FINE, "Planned Rate: {0}", dtRow.getPlannedRate());
if(dtRow.getPlannedRate()!= null && dtRow.getYtdProjectedSales() != null){
dtRow.setPlannedPAProjected(new BigDecimal(0.01 * dtRow.getYtdProjectedSales().doubleValue() * dtRow.getPlannedRate().doubleValue()));
}
logger.log(Level.FINE, "Planned PA Projected: {0}", dtRow.getPlannedPAProjected());
conRatesTabDisabled = true;
tabIndex = 1;
}

The plan is to call applyRowChangesMassUpdate via p:remoteCommand and disable the tab
using the PrimeFaces Javascript API. Here's how it can be done:
Give a widgetVar attribute to your p:dataTable for example dataTableWV.
<p:dataTable widgetVar="dataTableWV" value="..." var="...">
Give a widgetVar also to your p:tabView for example tabViewWV.
<p:tabView widgetVar="tabViewWV">
Add the call to applyRowChangesMassUpdate:
<p:remoteCommand name="applyRowChanges" actionListener="#{dealManagedBean .applyRowChangesMassUpdate}" />
Then use this script:
<script>
$(document).ready(function() {
//bind a function on table value changes
dataTableWV.tbody.context.onchange = function() {
//disable the tab you want by index, assuming the tab
//is the second one, its index will be '1'
tabViewWV.disable(1);
//selects view back to the first tab.
tabViewWV.select(0);
//call the 'remoteCommand' function
applyRowChanges();
}
});
</script>
This way, the rowEdit event is no longer needed, so just remove
<p:ajax event="rowEdit" listener="#{dealManagedBean.applyRowChangesMassUpdate}" update=":tbVUpdateDeals:tbVSelRates" />
Also you can remove
conRatesTabDisabled = true;
tabIndex = 1;
from applyRowChangesMassUpdate method, as the tab gets disabled, and the view is moved to another tab with a client-side code, which is better preferred to server-side code when a matter of view that is needed.
