I’m not sure, it works for me. Note, this is from Ignition 8.0.8. If you’re not getting any errors, then I’m not sure, you could try putting a Print statement in the drop function to insure you are getting the data transfered.
def drop(self,e):
e.acceptDrop(e.getDropAction())
paths = [[path] for path in e.getTransferable().getTransferData(ListOfQualifiedPath.FLAVOR)]
print paths
self._comp.data = system.dataset.addRows(self._comp.data,paths) if self._comp.data.columnCount > 0 else system.dataset.toDataSet(['Selected Tags'],paths)
