OK, so you're using the FlowJXPathSelectionList. The bad news is that this
particular SelectionList implementation does not seem to provide any public
methods for iterating over its items. But the good news is that since your
list of selection-list items is being built in your flowscript, you should be
able to fairly easily access it from flowscript that follows. You just have
to figure out how to get the "Lis" variable passed along to wherever you need
it. If it's within the same flow function then Lis should be available
directly. If it's in another function you can possibly pass it along as an
argument to that second function. Another possible way is to attach "Lis" as
an attribute to the field widget and access it later, like:
form.lookupWidget(campo).setAttribute("selectionListItems", Lis);
...
form.lookupWidget(campo).getAttribute("selectionListItems");
Then you can iterate over the items in Lis (I'm not sure what type of object
that is so I'll leave the details to you) to find the one with your target
value and get its label.
I hope this helps.
