Looking some jsf 2.0 code, I notice the current algorithm of  UIData.invokeOnComponent cannot handle the case when the target is a UIColumn instance and no rowIndex is on clientId. Is that ok?

Checking the new visit tree api, UIData.visitTree cleary says:

"....If this component has children, for each UIColumn child:

Call VisitContext.invokeVisitCallback(javax.faces.component.UIComponent, javax.faces.component.visit.VisitCallback) on that UIColumn instance. If such a call returns true, terminate visiting and return true from this method.

If the child UIColumn has facets, call UIComponent.visitTree(javax.faces.component.visit.VisitContext, javax.faces.component.visit.VisitCallback) on each one....."

I think we should do something like this:

                for (Iterator<UIComponent> itChildren = this.getChildren().iterator();
                        !returnValue && itChildren.hasNext();)
                    UIComponent child = itChildren.next();
                    if (child instanceof UIColumn && clientId.equals(child.getClientId()))
                        try {
                            callback.invokeContextCallback(context, child);
                        } catch (Exception e) {
                            throw new FacesException(e);
                        returnValue = true;
                    // process the child's facets
                    for (Iterator<UIComponent> itChildFacets = child.getFacets().values().iterator();
                            !returnValue && itChildFacets.hasNext();)
                        //recursive call to find the component
                        returnValue = itChildFacets.next().invokeOnComponent(context, clientId, callback);

Does that sounds reasonable? Should be fixed on 1.2.x branch too?
