Question

I am using RichFaces with seam and EJB3. Specifically I am using the rich:tree component. The problem I am worried about is the tight coupling between the UI and my EJB3 session bean. In order to make the tree view work, I was forced to include the Richfaces jar files in my EJB3 project. Is this a bad thing?

The method below is called when a node is selected in the RichFaces tree component. Adding this method to my session bean was what caused me to need to include the RichFaces jars.

public void processSelection(NodeSelectedEvent event) {
    HtmlTree tree = (HtmlTree) event.getComponent();
    selectedNode = (String) tree.getRowData();
}

Am I doing this all wrong, or is this not really a problem to worry about?

Answer 1

I’d suggest:

• getting the HtmlTree in a managed bean and parse its data, transforming it to a usable data-structure with no UI-elements.
• pass that data to the EJB.
