             Summary: Rich-DataTable: RenderPhaseDataScrollerVisitor swallows exceptions when thrown in isRendered
                 Key: RF-12001
                 URL: https://issues.jboss.org/browse/RF-12001
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.3.1
         Environment: Liferay 5.2.4, Facelets, JSF 1.2
            Reporter: Markus Staab


We implemented our own SerializableDataModel.
This datamodel throws an Exception in case the backend is not available or has some technical issues.

Our exception is swallowed by 
org.richfaces.component.RenderPhaseDataScrollerVisitor.isRendered(List<UIComponent>).

Is there a reason why all exception are catched in this situation?


	private static boolean isRendered(List<UIComponent> components) {
		boolean rendered;
		
		for (UIComponent component : components) {
			rendered = false;

			try {
				rendered = component.isRendered();
			} catch (Exception e) {
				//ignore that
				if (log.isDebugEnabled()) {
					log.debug(e.getLocalizedMessage(), e);
				}
			}
			
			if (!rendered) {
				return false;
			}
		}
		
		return true;
	}
