Quoting Brian Milby <br...@milby7.com>:
Could you open a bug report/enhancement request for this? I’ll see
what I can do about a PR targeting 9.1 release.
I can think of several ways to address the situation. Easiest would
be to reset the array that handles what is expanded when the data
array is changed. Would not be hard to add a separate handler to
collapse all nodes.
Once done, you could pull the updated source and compile/use locally
until it makes it into a release.
Thanks,
Brian

Setting the arrayData to EMPTY acts the same as setting the arrayData
to some other array: the open nodes remain open. I even tried changing
the number of elements in the array to something as low as 1 but it
still remembered what nodes had been open when setting the arrayData
to something with more elements.
There are no properties in the dictionary that describe this type of
operation. The closest I could find was hilitedElement but that
doesn't actually open or close a node leaf. In fact, if you set the
hilitedElement to a node that isn't open it will hilite the next node
that is open instead. (bug?)
This isn't critical for this project as it is just an internal tool
that only I use, but the only workaround I could come up with is to
delete the widget and then create the widget again via script along
with all the attributes.
