Has anything changed in newer versions of CPLEX? Is there any other way I can send an object to a child node if I cannot use makebranch to do that?

Thank you,

In current version of OPL (12.x up to 6), there is no way to send node data in branch thanks to the Java API provided in the oplall.jar

We will look to remove this limitation for a next release.

Thank you. It would be realy useful if oplall.jar could have those features in the future. As for now, I could do it in a different way. makebranch returns node id of the new node; hence, it is possible to store node's data in an external hash table indexed by the node id. This is not an ideal solution becasue the hash table has to be accessed for every node. Sending node data directly using parameters of makebranch would be much more efficient.
