Changes to the BPEL process are not deployed automatically after save.

1) Precondition: Say_Hello example project is imported in workspace and deployed to the SOA runtime. Test output with web service explorer.
2) Make changes to the process: Change the assign activity, for example change the concat function body to assign another message to the ReplySayHelloVar variable.
3) Save the process.
4) Server act as it is republishing, but it is not! Changes are not deployed. You can test with web service explorer again. The only scenario that works is to remove and re-add the project to the server runtime via "Add and Remove..." dialog.
