pc.upload does not support event handler list

[evandeng2009]

Describe the bug pc.uolpad, followed by pc.icon: pc.icon(tag="arrow_up", on_click=[lambda: State.assign_tid(item[1][1]), lambda: State.handle_upload(pc.upload_files())] And handle_upload will read a base var setted by assign_tid to rename the file.

Problem is: I see assign_tid has been executed, while handle_upload not. If this is not supported, anyway to rename the uploaded file with a dymanic and specified one?

Yes, the pc.upload_files() cannot work in the event chain.

I need to rename the file according to the place where upload button is clicked. Anyone knows how to do this as a workaround before event chain finally is supported please?
