Hi,
In one of the tasks I have been required to output the data, which comes both from Product BOL-entity (model node) and from regular function (value node). In order to do that I defined a context node (CN) in component controller and in desired view and binded them. This CN is a mixed node, since it's based on model and value nodes at the same time.
I succeeded to fill-in this CN with the data, but I faced out with the problem at the step of data retrieving from the context node. After some debug I found out, that I get an casting exception in GET_attr_name( ) method (default wizard's implementation), when I'm trying to cast variable of CL_BSP_WD_MIXED_NODE to CL_CRM_BOL_ENTITY, in order to execute get_related_entity( ).
My question is how can I solve/avoid this problem and achieve the access to related entity of mixed node?
Thanks.
