Fix of CORBA ORB not working

[mortenhaahr]

The NuRV Monitor Service example stopped working. @Valdemartt found some bug fixes that are introduced in this PR.

@mortenhaahr The lifecycle/create script for this DT is not installing as many packages as that of plain incubator script. Is there a tacit assumption of using plain Incubator DT before using the DT with NuRV monitor service? Thanks for the clarification.

@Valdemartt and @mortenhaahr There seems to be a subtle error when executing this DT. There was an error when it was run the first time but works when it was run again.

No. This is a bug. I fixed it in the latest commit.

We are aware that there are some instability issues in this example. But once it gets started then it is stable.

Do you still have the error logs of it??

Had the same error happen to me but it also disappeared when retrying. If it continues I might look into it in a separate fix.

@mortenhaahr I get the following error on a clean workspace.

I cannot replicate this. I tried to delete my examples folder and rerun the example but it worked as intended. I also verified that omniorb-py is installed in the create script and everything appears good. Did the create script successfully execute?

@prasadtalasila can you provide details on this and whether it still happens?

[prasadtalasila]

@mortenhaahr The example works for me now. I might have been using the commit before updating the installation script. Thanks for rechecking everything.
