-----------end_max5_patcher-----------

on the console you will find the following output:

print: node created sparck:/empty
print: node created sparck:/empty/toggle
print: parameter created sparck:/empty/toggle

1. open subpatcher "workspace"
2. copy paste subpatcher "empty"

the folloing output appears:

print: parameter removed sparck:/empty/toggle
print: node removed sparck:/empty/toggle
print: node removed sparck:/empty
print: node created sparck:/empty
print: node created sparck:/empty/toggle
print: parameter created sparck:/empty/toggle
print: node created sparck:/empty.1
print: node created sparck:/empty.1/toggle
print: parameter created sparck:/empty.1/toggle

The printout of step 2 indicates that the node tree has been rebuilt. In my opinion this is undesired behaviour. It shouldn't rebuild the whole node tree, but only add the new nodes sparck:/empty.1 and sparck:/empty.1/toggle.

case in point:

3. repeat it again:

print: node created sparck:/empty.2
print: node created sparck:/empty.2/toggle
print: parameter created sparck:/empty.2/toggle

doing it a second time doesn't rebuild the node tree.

This behaviour is undesired because once you load a patcher and load parameters into the node tree and then add another node, you loose all the parameters loaded and you have to reload them again.

I updated the above bug report to make the issue clearer to reproduce and understand.
