Best way to use Stage Position List for multi_d_acquisition_events

[jones-lab-tamu]

I am trying to run a multi_d_acquisition_events() acquisition to image a slide, and I have managed to figure out how to generate a coordinate list that is saved in the Stage Position List in micro-manager, but I cannot find any good way to use this with multi_d,
calling get_positions() on positionList returns
<pyjavaz.bridge.[Lorg_micromanager_MultiStagePosition; object at 0x000001CA4B636420>
rather than a list of positions. trying to call get_x() or get_y() at any index on this object or on positionList throws an error.
And finally, trying to save the list as a json file to be parsed using save() creates a file with an empty coordinates list.
Is getting the coordinates into a list for the acquisition necessary, or is there some way to tell the acquisition to use the coordinates already saved in micromanager?
If the list is necessary, how do I actually get a list of coordinates from micromanager to use?

Thanks

You're calling the Java side position list code. To access the positions in there you'll need to convert them to python objects using the Java API somehow
