Hi, I have included a small cut down version of something I am trying to do.?

I set up a propertyChangeLlistener for a sensor. When the sensor is activated it runs. I have simulated it running a long time just by putting a time.sleep in.
My problem is that when the se.setSate(ACTIVE) in the main function runs. It does not complete until the propertChangeListener completes.

Is there a way to have the propertyChageListener run without the main function waiting for it to complete.

I have looked at some of the documentation on threads but do not understand how to get this to work with jython.
I have used threading.Thread from the standard library start a thread running to do the long running task but this has some really strange behaviour and does not appear to run as? thread but runs sequentially.?

Some examples of why I want to do this is that when a sensor is activated I want to set a function key on the throttle a number of seconds later and not at the time the senor is activated or to start running some animation program on the layout that
could take some time.?

Thanks jim.

Thanks for the help!

I created the Decoder File for the Digital Bahn WaLD Decoder and it works. So from now on, i can set up the interior lightning stripe with decoder right aut of jmri.
I think, i will upload the files to the projekt, so everyone can use them in future.

I have a small track that has been successfully running DCC++ connected to a Raspberry Pi currently running PanelPro 4.6.? I am attempting to add block detection using a BDL168 and PR3.? I use TightVNC on a laptop for programming the RPi.

First, the track was cut into 16 blocks with feeders thru the BDL and the train ran normally.? Next, BDL OpSw 12 was set to "t" to terminate the LocoNet, and track power from Rail A was connected to pin 6 on the LocoNet to provide a RailSync signal per the BDL manual.

Opened Preferences to add a second connection: Mfr - Digitrax; Connection - LocoNetPR3; Serial port - /dev/ttyACM1; Cmd station - Stand-alone LocoNet.? Saved and restarted.

The console window shows -?
Active profile: DCC++
DCC++: using DCC++ Serial port on /dev/ttyACM0
LocoNet: using LocoNet PR3 on /dev/ACM1

The track power button is stuck on "Unknown".? Removed and added the PR3 to Preferences a couple of times with the same results.? Tried Steve Todd's latest image v4.18 with the same results.

What am I missing?? Where do I look next.? It's probably something simple that I have overlooked.

Thanks for any help or suggestion you may be able to offer.

Dave,
Where is the new CATS group?
Thanks,
Ray Eiser

Rodney,
Thanks.? We read about CLEAR is section 6.2 but it didn't sound like what we wanted to do yet it is exactly what we were looking for.? CATS is working well so far.
Dave...

Are drivers installed for the LocoBuffer?

Cliff,

The way we usually do this is via the release notes, which everyone reads religiously ;-)

More seriously, for something like this we try to minimise the times that we make such changes and, when we do, update our script samples to show how the new libraries work.

In general, we also try to introduce these sorts of changes earlier on in the development release schedule such that the impact of changes can be better assessed and understood prior to a future Production release and, if needed, work out better documentation and/or tooling to aid migration.

Best regards,

Matt H

Yesterday everything was working correctly: turnouts, sensors, signals, blocks. Today I tried to work offline. Everything in the tables was converted to internal devices. I tried opening some backups of the XML files and most, not all, of the devices were now missing from the tables and what was there was still internal. Offline work seems to be a mistake. Is there a way to recover from this mistake?

I am using windows 8 on an ASUS notebook.

Thanks,

John

Matt,

There is every reason for me to suspect that the answer will be NO, but is there a manageable way to declare a Jython import library as depreciated? Introducing a replacement library for improvement reasons might go smoother if that act did not invalidate a lot of home-brew scripts.

The more thought I give to the CSV change, which is not backward compatible, it seems that Sam may have acted as the flag-bearer for a large number of members with legacy scripts.

Our club has chosen to not use anything other than production versions. That means my laptop has both the production and test versions. Occasionally I use NetBeans "Pull from Upstream" from GitHub updates to be able to debug a script by reading small snippets of Java source code. I am not a Java programmer, but sometimes I can read portions of the code and insert breakpoints. Usually a newly developed or edited script can be more robust if tested with up to date code.

My point is, that backward compatibility is important to me, since most JMRI issues, either script or Logix, are dealt with at home instead of at the club. There is a lot of reason to expect that I am not alone in this regard.

Why does JMRI pick it up as a v5?

Because it must be a V5. As Michaelhas said, Atlas obviously hasn't updated the manual.

"G",

Which "reporter" hardware are you using? It makes a difference.

If you are using Digitrax transponding, I know that it has some configuration settings which affect how reports are generated by the hardware, and perhaps one of these may help you achieve your goals. I vaguely recall that there are some limitations on what the hardware will/will not report.

I am not currently a user of any sort of "reporter", so cannot provide much help other than what I've mentioned about Digitrax, above.

Regards,
Billybob

Mick.That is fine unplug it gone plug it in back and two green lights on.
Under preferences where you enter Digitrax then Locobuffer usb the next box to enter
Com 3 not there, or opening for me to enter…
also the Digitrax and Locubuffer usb selection will not save! Steve….

IIRC this uses an FTDI chip in which case there is a two stage
installation process as there are two software modules needed. Have
you installed the second module? It sounds like only the first has
been installed, which talks to the USB, and not the second that
creates the COM port.

Have you installed the Locobuffer drivers? Can you see it in Windows Device Manager, and watch it come and go as you plug it in and out. If you can’t see it in Device Manager, the neither can JMRI..
