Expand dynamic tree in WebDynpro

[Former Member]

Hi all,

I've made a WebDynpro application with a dynamic tree and I want the tree to be expanded when I start the application.

I've made the application following the wdt_tree demo.

Until now I managed to display only the first level nodes when I open the application.

Do you have any ideas  how to make the whole tree expanded?

Best regards,

Dana

Hi Dana

I had a similar reaction with the tree-UI.

My error was, that on WDDOBEFORE-Action I had a method, where my expande-node were been deleted directly in the context.

if you have a method in WDDOBEFORE-Action where you read or change the expande-node, than take a look in the debugger (with the webdynpro-special-tool in the debugger), if the attribute "Expanded" is really set an X.

if you haven't luck, than post the code, maybe I can help you.

Best regards

Lorenzo
