External context mapping with recursive treenode

[Former Member]

Hi,

did anybody succeed with external context mapping of a recursive tree node?

I get the following runtime error. Everything works fine if I use a "regular" value node. I´ve also experimented with manual and automatic component creation.

Any help is appreciated

Helmut

Hi Helmut,

I face exactly the same problem with NW 2.0.7.

It is a bug in WebDynpro runtime.

Good news is that it is fixed with SP9, so this functionality will work in final release (I believe WD team uses regression tests
