#31 Impossible to save a graph containing inhibitor arcs

[abraham]

When saving a file containing at least one inhibitor arc, I get the following error message in a MessageBok :
java.lang.IndexOutOfBoundException: Index:0, Size: 0

The trace in the console is the following :

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

This bug is still present in Pipev4, 30/09/2011

I have a fix for this bug.
In PIPEv4_src/src/pipe/utilities/writers/PNMLWriter.java, line 378:

Change the code to:
String weightOutput = "";
for(int i = 0; i < weightInput.size(); i++)
{
if (i != 0)
weightOutput += ",";
weightOutput += weightInput.get(i).getToken().getID() + "," + weightInput.get(i).getCurrentMarking();
}
to avoid the null pointer.

I would change the code myself, but I don't know how.

Fixed in v4.1.
