Fab Mars created RF-12647:
-----------------------------
Summary: rich:dataTable rowclick changed scope
Key: RF-12647
URL: https://issues.jboss.org/browse/RF-12647
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-tables
Affects Versions: 4.3.0.M2
Environment: Win7, JDK7, Glassfish3, Mojarra 2.1.14, SeamFaces, RF
4.x.x
Reporter: Fab Mars
During my migration from RF 3.3 I found this:
Before (with RF 3.3.3):
{code:xml}
<rich:dataTable id="shippingList" value="#{billingLister.allShippings}"
var="shipping">
<a4j:support event="onRowClick" reRender="shippingEditForm">
<a4j:actionparam name="shippingId" value="#{shipping.id}"
assignTo="#{shippingEdit.id}"/>
</a4j:support>
<rich:column>
<f:facet name="header">
<h:outputText value="Destination"/>
</f:facet>
<h:outputText value="#{shipping.destinationCountry.name}" />
</rich:column>
<!-- other columns here -->
</rich:dataTable>
{code}
There was nothing really impacting on the migration guide
https://community.jboss.org/wiki/RichFacesMigrationGuide33x-4xMigration-ComponentsMigration-RichIterationComponents
So I logically did that with RF4.x.x:
{code:xml}
<rich:dataTable id="shippingList" value="#{billingLister.allShippings}"
var="shipping">
<a4j:support event="rowclick" render="shippingEditForm">
<a4j:actionparam name="shippingId" value="#{shipping.id}"
assignTo="#{shippingEdit.id}"/>
</a4j:support>
<rich:column>
<f:facet name="header">
<h:outputText value="Destination"/>
</f:facet>
<h:outputText value="#{shipping.destinationCountry.name}" />
</rich:column>
<!-- other columns here -->
</rich:dataTable>
{code}
But the a4j:aja isn't triggered. To start having something that works, one
needs to remove the a4j:param and do it straight.
{code:xml}
<a4j:ajax event="rowclick" render="shippingEditForm"
listener="#{shippingEdit.setId(shipping.id)}"/>
{code}
Not sure this is a regression or not, but wait, here's more: when one clicks on
a row with that code, he gets an ArrayIndexOutOfBoundsException because the
clientID that's actually passed into UIDataAdapter#invokeOnRow is the id of the
dataTable itself. Hence String rowId = clientId.substring(baseId.length() + 1);
So...to make it work, you have to actually declare the <a4j:ajax
event="rowclick" /> in the <rich:column/>
Overall that makes quite a difference between RF 3.3 and RF 4.x. I'd say a
regression. Or at least that needs an extra clarification in the documentation
and migration guide.
