Hi.
We have a large app being developed by several people. We are using OD 6.0.0.1301. One of the developers has recently had a NPE appearing when he tries to put a subflow node. Whenever he puts the node, the properties box is empty (it should have the name of the subflow and a combo to select the actual subflow). Te standard solution of restarting Eclipse is not working/ The error log has the following:
java.lang.NullPointerException
