hopefully somebody can help me out because I'm having some strange problem with Databinding in one of my MVC-BSPs.
When executing I am running into an "SAP Internal Server Error" telling me that there is a parameter missing for a dynamic function call.
After some debugging and testing the code triggering this is within my view:
<htmlb:dropdownListBox id = "x_y_ddb" table = "<%=w_table%>" selection = "//mymodel/my_table.w" nameOfKeyColumn = "name" nameOfValueColumn = "value" disabled = "<%=flag%>" > </htmlb:dropdownListBox>
This code was running ok last week. After some modifications in the model- and the controllerclass it is not running anymore. The strange thing is that I did not change anything regarding the used table or the attributes...
When debugging I found out that the method causing the error is "selection_model->get_attribute( attribute_path = selection_path )."
The attribute selection_path is correctly filled with "my_table.w". So all needed parameters are filled as this is the only one passed.
The method is called from "RESOLVE_MODEL_BINDING" of class "CL_HTMLB_DROPDOWNLISTBOX".
After trying a few things I have no more ideas. The error only occurs when binding to the table. Upon binding to a structure or to a field ev erything works fine.
Thing is, Im am 99% sure this worked last week and I can't remember having changed anything directly connected to this. I am still able to see the data that was created during testing last week.
Any ideas for me?
