[richfaces-issues] [JBoss JIRA] (RF-12647) rich:dataTable rowclick with nested f:param

rich:dataTable rowclick with nested f:param ------------------------------------------- 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|title="RF 3 Sample"} <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-C... So I logically did that with RF4.x.x: {code:xml|title="RF 4 Sample 1"} <rich:dataTable id="shippingList" value="#{billingLister.allShippings}" var="shipping"> <a4j:ajax event="rowclick" render="shippingEditForm"> <a4j:param name="shippingId" value="#{shipping.id}" assignTo="#{shippingEdit.id}"/> </a4j:ajax> <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:ajax isn't triggered (not at all, it's NOT a param assignment issue). To start having something that responds, one needs to remove the a4j:param and do it EL-newlook style. {code:xml|title="RF 4 Sample 2"} <a4j:ajax event="rowclick" render="shippingEditForm" listener="#{shippingEdit.setId(shipping.id)}"/> {code} Anyhow we're close to RF-11446 and whenever that one gets fixed, one should check whether this case here is also solved. But wait, even that doesn't work: when one clicks on a row with that code, the listener is called but an ArrayIndexOutOfBoundsException is thrown because the clientID that's actually passed into UIDataAdapter#invokeOnRow is the id of the dataTable itself, NOT this of the row/cell. Hence, String rowId = clientId.substring(baseId.length() + 1) ends up tragically. So...to make it really work, you have to do what's described here: https://community.jboss.org/thread/174063 and not fall into the trap of RF-11446. Working code (RF 4.2.3+) {code:xml:xml|title="RF 4 Sample 3"} <a4j:jsFunction name="shippingListRowClick" render="shippingEditForm"> <a4j:param name="shippingId" assignTo="#{shippingEdit.id}"/> </a4j:jsFunction> <rich:dataTable id="shippingList" value="#{billingLister.allShippings}" var="shipping" onrowclick="shippingListRowClick(#{shipping.id});"> <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} All that...for that. Overall that makes quite a difference between RF 3.3 and RF 4.x. I'd say we have a couple of regressions. Or at least that needs an extra clarification in the documentation and migration guide. Thank you.
