Hello!

I'm attempting to use savestate to keep track of the number of cells and current value of a Vradio object in an abstraction to use a GUI element. A minimal example can be seen here:

Unfortunately, when using and then saving the abstraction, I get errors like

(Tcl) INVALID COMMAND NAME: invalid command name ".xb68310.c"
while executing
".xb68310.c delete bae6d0BASE0"
("uplevel" body line 13)
invoked from within
"uplevel #0 $docmds"

This seems beyond what i can decipher. Am i doing something very wrong in my abstraction or is this a bug?

Thanks

@sbh I think that could be considered a bug, but it is also a conflict between the concepts of [savestate] and Pd GUI management.

[savestate] is carried out before the GUI is initiated, so the number is being set before the radio even exists.

You can circumvent this by delaying the float to the [number $1( message. Adding [pipe] after the first outlet of [unpack] solves it.

Still it could be useful to report this bug.

Edit: This could still conflict with the value of the radio. So it would be better to store the list from savestate in a [list] and execute it after loading with [delay].

Therefor i would also change the order: First set the size and after that set the value. Otherwise the value could be lost if it is higher than the original size.

Demo: savestate_delay.zip

@ingox Thanks a lot for the insight and for confirming my suspicion, that something wasn't quite right. Nice workaround.

And you are totally right about the ordering of the size and value needing to be reversed, so it'll work when the size and value are both above 8 (the Vradio default size)
