    Very strange exception

    Gus Gu Expert

      Hi all,
      I don't know what I did wrong recently. After I deployed codes to a running jboss server, I always got the exception shown below when I begin to run it, exception that I shut down server and restart. This is very boring exception. Every time when I modify codes and deploy it to server, I always have to shut down server and restart it. Can anybody give me some advice? Thank you in advance.

          • 2. Re: Very strange exception
            Gus Gu Expert

            I guess that the exception listed in first thread was from Tomahawk tree2 component. When using tree2 with facelets, it needs a Tree2TagHandler. The code is listed as follows(from myfaces wiki), but I haven't got chance to test it.

            import java.util.Map;
            
            import javax.faces.component.UIComponent;
            
            import org.apache.myfaces.custom.tree2.HtmlTree;
            import org.apache.myfaces.renderkit.JSFAttr;
            
            import com.sun.facelets.FaceletContext;
            import com.sun.facelets.tag.MetaRuleset;
            import com.sun.facelets.tag.jsf.ComponentConfig;
            import com.sun.facelets.tag.jsf.ComponentHandler;
            
            public class Tree2TagHandler
             extends ComponentHandler
            {
             public Tree2TagHandler(ComponentConfig cfg)
             {
             super(cfg);
             }
            
             @Override
             @SuppressWarnings("unchecked")
             protected void onComponentCreated(FaceletContext ctx, UIComponent c, UIComponent parent)
             {
             super.onComponentCreated(ctx, c, parent);
            
             HtmlTree component = (HtmlTree)c;
            
             Map attrs = component.getAttributes();
             ensureBoolean(attrs, JSFAttr.SHOW_NAV);
             ensureBoolean(attrs, JSFAttr.SHOW_LINES);
             ensureBoolean(attrs, JSFAttr.CLIENT_SIDE_TOGGLE);
             ensureBoolean(attrs, JSFAttr.SHOW_ROOT_NODE);
             ensureBoolean(attrs, JSFAttr.PRESERVE_TOGGLE);
             }
            
             @SuppressWarnings("unchecked")
             private void ensureBoolean(Map attributes, String attrName)
             {
             Object value = attributes.get(attrName);
             if (value == null || !(value instanceof String)) return;
             attributes.put(attrName, Boolean.valueOf((String)value));
             }
            
             @Override
             protected MetaRuleset createMetaRuleset(Class type)
             {
             return super.createMetaRuleset(type)
             .alias("showNav", JSFAttr.SHOW_NAV)
             .alias("showLines", JSFAttr.SHOW_LINES)
             .alias("clientSideToggle", JSFAttr.CLIENT_SIDE_TOGGLE)
             .alias("showRootNode", JSFAttr.SHOW_ROOT_NODE)
             .alias("preserveToggle", JSFAttr.PRESERVE_TOGGLE);
             }
            }
