Lost with "Trees" how to???

[Former Member]

Hi guys!

My goal is to rebuild something like psv2 (business event menue) in web dynpro.

But I'm really getting lost with "trees" there. Actually i have no idea how to start and handle trees.

I can't have a look at the WDR_TEST_EVENTS because this services are somehow disabled in our environment,

Does someone have some good Tutorials (step by step) how to work with trees?

I couldn't find any step-by-step tutorials on the subject. Although you may have already found it, the online help link has a decent amount of details:

http://help.sap.com/saphelp_nw70/helpdata/EN/21/ad884118aa1709e10000000a155106/frameset.htm

Also even if you can't run the sample application (probably just because the service node is deactivated - you can go to SICF and activate it), you can still study the source code.

Do you think that you will be needing a very dynamic tree structure (in which case you would model a recursive node context) or do you know the tree structure at design time (in which case you simply model that structure in the context)?
