Of course. I should have done that to begin with, sorry.

The following code causes a solver exception that reads "cant initialize Alternative Edge finding TL Tree" in version 2.1.0 of choco.
model.addConstraint(Choco.eq(Choco.plus(JobA_Res1, JobA_Res2), 1));
model.addConstraint(Choco.eq(Choco.plus(JobB_Res1, JobB_Res2), 1));
model.addConstraint(Choco.eq(Choco.plus(JobC_Res1, JobC_Res2), 1));
model.addConstraint(Choco.disjunctive( new...

I have noticed that the above approach works great for most situations, but I'm still getting errors in some instances. For example, the following code causes a solver exception that reads "cant initialize Alternative Edge finding TL Tree."
model.addConstraint(Choco.eq(Choco.plus(JobA_Res1, JobA_Res2), 1));
model.addConstraint(Choco.eq(Choco.plus(JobB_Res1, JobB_Res2), 1));...

That does help, thanks. I have the alternate resource approach working for my application now.

Out of curiosity, why does something like this not work:
Constraint ResourceA = Choco.disjunctive(new TaskVariable[ ]{Task1, Task2});
Constraint ResourceB = Choco.disjunctive(new TaskVariable[ ]{Task4, Task5});
Constraint temp = Choco.or(Choco.disjunctive(new TaskVariable[ ]{Task1, Task2, Task3}), Choco.disjunctive(new TaskVariable[]{Task4, Task5, Task3}));.

I cannot find a disjunctive method with that signature. I am using choco 2.0.0.3 -- do I need to switch to a later version?
Here is what my test code looks like. Task1 needs ResourceA and ResourceB in order to complete. Task2 needs only ResourceB. Task3 needs either ResourceB or ResourceC. The code fails on ResourceB.addOptionalTask(Task3).

Is there a way in the scheduling package to specify that TaskA needs to use either MachineA or MachineB, but not both?.

I knew I should have poked around more before posting that question. CumulativeResource for the win.
