Hi,
Maybe I'm doing something wrong but expectedRusltData doesn't work for batched items.
I'm trying to get value from resultData to downstream parameters.
Can you please take look at example files:
Thanks

The issue is that the files are being added during the onPrepareTask hook. That code runs immediately before the work items are scheduled, which happens after the graph has been generated. It's typically used to add information that's only know right before a work item cooks, such accessing outputs from cooked dependencies upstream in the graph. The attribute create is doing its evaluation and adding its attributes when the work items are generated.
If you know the file paths ahead of time, you may want to do something the following instead (I modified the onGenerate in your .py file):
That's also an example of how you can have a per-frame expected output file on each item in the batch. That's effectively what the ROP Fetch node is doing, except it gets the file path by evaluating the output file parm on the target ROP.

def onGenerate(self, item_holder, upstream_items, generation_type): item = item_holder.addWorkItem(batch=True, batchSize=1) item.setFrame(1, 1) item.setCommand("hython -c {}".format(python_exec)) for sub_item in item.batchItems: sub_item.addExpectedResultData("someoutput.{}.bgeo".format(sub_item.frame),"custom/tag")
