> Ajax component processing outside of region/form

> Key: RF-7192
> URL: https://jira.jboss.org/jira/browse/RF-7192
> Project: RichFaces
> Issue Type: Bug
> Components: component-a4j-core
> Affects Versions: 3.3.0
> Reporter: Thomas W
> Assignee: Nick Belaevski

> RF 3.3.0 GA
> Issue with server side processing of AJAX enabled components that are outside
> of any region that is requested to be rendered as well as any a:outputPanel
> with ajaxRendered="true". This happens with tree and table components, for
> example.
> I could track this down to behavior in UIDataAdapter. With the following
> change the unwanted processing is turned off:
> public void encodeAjaxChild(FacesContext context, String path,
> final Set<String> ids, final Set<String> renderedAreas) throws IOException {
> boolean isRenderedPath = false;
> for (String id : ids) {
> if (id.startsWith(path)) {
> isRenderedPath = true;
> }
> }
> if (!isRenderedPath) {
> return;
> }
> With this addition, any component that falls outside the list of requested
> ids (reRender) will be skipped. This has muted the excessive component
> processing (processing that would never result in DOM rendering).
> A real fix would need to allow for processing of outputPanels with
> ajaxRendered="true". What is the correct fix for this problem?
> <a:outputPanel id="searchResults" ajaxRendered="false"
> styleClass="noBorder">
> <a:region>
> <h:form id="searchForm" styleClass="noBorder">
> <rich:scrollableDataTable ....
> <a:support event="onselectionchange"
> action="#{someAction.process}" reRender="region1,region2"
> limitToList="true"
> status="globalStatus"/>
> Call originates from AjaxChildrenRenderer.encodeAjaxComponent:
> if (!found) {
> if (component instanceof AjaxChildrenEncoder) {
> ((AjaxChildrenEncoder)
> component).encodeAjaxChild(
> context, currentPath, ids,
> renderedAreas);
> } else {
> Stack trace:
