[plexil-support] Plexil Viewer not working correctly in 4.5.0RC2?

[Martin F. <mar...@un...>]

Hello,
I installed plexil-4.5.0RC2 and was trying to execute an example plan in
the Test Executive. I followed the description on
http://plexil.sourceforge.net/wiki/index.php/Viewing_Plan_Execution

In the directory examples/basic I entered

plexiltest -v -b -p DriveToTarget.plx -s scripts/DriveToTarget.psx

Then the Plexil Viewer Console opens, saying:
STATUS: Listening on port 49100

Also the Plan View opens and shows the tree structure of the plan.
When I select Run - Execute Plan an error message shows:

Can't execute DriveToTarget.
No  executive has been selected for this plan.

When I select File - Plan Settings PlexilTest is already selected.
I select the same Sim Script as in the command line argument.

Again I select Run - Execute Plan.
In the Plan View's status bar it shows:
Execution complete

There is no pause at the beginning of execution.

In the Plexil Viewer Console it shows:

Using Test Executive...

Socket.cpp(62) MARK
WARNING: ExecTestRunner.cc:309: WARNING: Unable to connect to Plexil
Viewer:
  address: localhost:49100
Execution will continue without the viewer.

This does not match the description in the wiki. Is the documentation
outdated or am I doing something wrong?

Also closing the Plexil Viewer Console is not possible. It's not closing
but stops responding. I need to xkill it.

OS is Debian GNU/Linux 9.9 (stretch)
java is openjdk version "1.8.0_212"

Best,
Martin
