Hi list, hi Tiago,
First thank you for graph tool, that's a great package.
I run in a very strange problem when reloading a xml graph file with an
'internalized' PropertyMap.
the minimum script does the following:
* test1: create, internalize the PropertyMap pos1, save the graph in xml
* test2: load the graph from xml, read the internalized PropertyMap pos2
Depending whether the two tests are ran in separate processes are in the
same process, the two Propertymaps will not have the same values:
test1 and 2 in the same process:
pos1 == pos2
test1 and test2 in different processes
pos1 != pos2
