HtmlDropSupport + Component Binding = IllegalStateException?

tnyh Dec 8, 2011 7:20 PM

Hi, is the first time I've had to ask a question, so lets hope I don't muck this up

I've run into a problem. I've set up a page with an a4j:outputPanel bound to HtmlAjaxOutputPanel in my backing bean. Like so:

{code:xml}
<a4j:outputPanel id="workSpace" layout="block" style="text-align:center;">
                    <a4j:outputPanel  binding="#{ReportDesignerBean.workSpace}"></a4j:outputPanel>
</a4j:outputPanel>
{code:xml}

The HtmlAjaxOutputPanel is created thus:

{code}
HtmlAjaxOutputPanel dropTarget = new HtmlAjaxOutputPanel();
dropTarget.setStyleClass("dropTarget");
dropTarget.getAttributes().put("layout", "block");
dropTarget.setStyle("height:"+(int)(report.getPageHeight()/4)+"px;width:"+(int)(report.getPageHeight()/4)+"px;margin:3px;position:absolute;top:"+y+"");
dropTarget.setId("lowerDropTarget");
                
HtmlDropSupport dropSupport = new HtmlDropSupport();
dropSupport.setAcceptedTypes("component");
dropSupport.setReRender("workSpace");
dropSupport.setId("dropArea");
        
dropSupport.addDropListener(new MethodExpressionDropListener(BeanUtil.createMethodExpression("#{ReportDesignerBean.addComponent}", null, new Class[]{DropEvent.class})));
dropTarget.getChildren().add(dropSupport);
                
workSpace = dropTarget;
{code}

The page displays correctly, but when a drop event occurs, via dropping a valid object onto the panel:
