Tcl-NAP is deleting my referenced object

[EKB]

Hello,

I am creating a Tcl-NAP object with the following statement:

set in [nap_get hdf $info(hdffile) "$SDS"]

where "in" is a namespace variable (call it namespace "foo"). Then I
use it later to view specific data points in the 3-d array:

set ::result [[nap "foo::in($::xval, $::yval, 0)"]]

But I can only do this once. After one use, I get the error
"Nap_Index: Left argument is unknown NAO ID ::NAP::15-14". So it looks
like it's deleting my object. But I've got it referenced!

Does anyone know what might be going on here?

Thanks,
Eric

I'm not sure how many Tcl-NAP users/developer read the list -- you may get
better response by posting your question on one of the mailing list
mentioned on the Tcl-NAP site (http://tcl-nap.sourceforge.net/).

Thanks! I posted on the Help discussion forum there, but mine was the
only post, so I wasn't sure it was active. I'll try that mailing list.

Well, I got a bounce when posting my message on the list, but I
figured it out anyway! Apparently, for an object to be retained by NAP
(which does garbage collection), it has to be assigned within a NAP
command, not using set. So this works:

nap "in = [nap_get hdf $info(hdffile) "$SDS"]"
