I’m going to post here about some bugs I’ve been confronted when developing.
There are things that can draw one crazy but during the testing you often find out how to “trick around” the bug.
It is not always possible to open incidents beause it costs a lot of time, and it is easier to use the trick and proceed with the work.
One thing I’ve just found out has to do with dedicated fields.
It seems to be inpossible to use the transformations in UI designer, never mind from the SAP Reuse Library or from your own, if your UI Data Model is not bounded to any BO. There is a dump whatever code is executed in the reuse library.
I’ve tested it in EC and I don’t know whether it’s the same in other screens.
To get rid of the dump just bind the Data Model to any BO. It is not necessary to perform a Read or Create operation on this BO, so if you don’t want to load any BO into the UI just bind your UI to any BO simply to avoid the dump.
