OK, I see the problem. The _modelNumber is associated with the frame change,
not the model loading, and that happens after all this callback stuff. I've
added two additional parameters to the callback:
* myLoadStructCallback(appID, fullPathName, fileName, modelName,
errorMsg, ptLoad, priorCurrentModelNumberDotted,
lastLoadedModelNumberDotted)
ptLoad = 3 for successful file loading
priorCurrentModelNumberDotted = "3.1" for example, or "1.1 - 3.31" if a
whole range of models is framed
lastLoadedModelNumberDotted = the file.model number for the very last model
loaded.
Will upload tomorrow.
* {}
*
* ptLoad == FILE_STATUS_NOT_LOADED == -1 ptLoad == FILE_STATUS_ZAPPED ==
0
* ptLoad == FILE_STATUS_CREATING_MODELSET == 2 ptLoad ==
* FILE_STATUS_MODELSET_CREATED == 3 ptLoad == FILE_STATUS_MODELS_DELETED
== 5
*
* Only -1 (error loading), 0 (zapped), and 3 (model set created) messages
are
* passed on to the callback function.

If nature does not answer first what we want,
it is better to take what answer we get.
