Re: Key path question

Hello,

I tried many possible paths given the suggestions and the output from "string_components". All throw an exception! Attached is a jpg of the patch. I hope attaching a 24K JPG is allowed.

If not, the patch is
2 "Constant Color->Crop"s going into a multiplexer.
The multiplexor goes to a billboard.

The selector for the multiplexor is tied to the value of "Structure Index Member" .

What should be done?

P.S.
My apologies to Pierre-Olivier. I keep forgetting to reply to the list, not you directly.

The members have no known name, they are accessed in QC via "Structure Index Member". How would a UI control or even Obj-C code populate or bind to that value?

"port key".value."member"

What would the member name be?

Use the tooltips to figure out what the structure looks like inside QC and you will see what are the keys.

I think it should be "port key.value.x, "x" being the index
