I know you can implement method IF_FPM_GUIBB~GET_PARAMETER_LIST in your OIF feeder class, to supply a list of parameters which you can then set with values against your GUIBBs.
How do you then use these parameetrs, i.e. what is the purpose, how do you exploit them, as you dont seem to have any further access to these parameters in other methods of your feeder class, for example IF_FPM_GUIBB_FORMGET_DEFINITION or IF_FPM_GUIBB_FORMGET_DATA to have some expression logic behind the setting of field lists/catalogs or data retrieval.
If anyone can indicate if/how these parameters can be exploited within the OIF feeder class I'd be most interested, as I would dearly love to use the parameters in order that I can create for example a generic feeder class for several GUIBBs on the same sub view and control the field catalog setting etc. (i.e. not create a seperate feeder class for each GUIBB).
