Hi Volker, I am steadily making progress with the component tree but I am still battling with a lot of basics. Maybe you can give me a hint:
1. Where do I find some documentation on which TobagoConstants.ATTR_* work on which component ? Is it along the lines of HTML ? 2. I create a combo box: UISelectOne combo = new UISelectOne(); combo.setId( id); combo.setRendererType( TobagoConstants.RENDERER_TYPE_SELECT_ONE_CHOICE); SelectItem[] items = new SelectItem [ 3]; for( int i=0; i < 3; i++) items[i] = new SelectItem( ""+i, ""+i); combo.setValue( items); The combo box is displayed, but disabled and does not contain any values. In general, what steps do I take to discover what the problem is ? Thanks, Peter -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!
