I have to set a selection list on a field, based on success or failure

When I use the following fragment:
TntCformsJavaSelectionList mySelectionList = new
TntCformsJavaSelectionList(true);
mySelectionList.setDatatype(new StringType());
myField.setSelectionList(mySelectionList);
I get an error: Tried to assign a SelectionList that is not associated
with this widget's datatype.
then why not do:
mySelectionList.setDatatype(myField.getDatatype());
?
I think I had similar situation, with this answer to the question above: you may
want to share potentially large selection list(s) between multiple widgets, here
widgets might be on the same form, or even on multiple forms for multiple users.
It could be quite substantial memory savings... In this scenario, you need
either multiple widgets have same instance of datatype on multiple widgets (is
it even possible?), or use equals() instead of '==' as was suggested.
