Another very minor bug I've been experiencing:

When a caboose is assigned to a train, the car shows on the 'Cars' page with the load I have set - normally either 'E', or the custom load 'Crew'. However when the manifest is previewed or printed, the 'load' column is blank.

Greetings, I have noticed at the bottom of the Decoder Pro -> Roster -> Media tab sometimes there are two custom attributes, LastOperated and OperatingDuration that are displayed. I see the same in the xml files. I love this information. I can not find how to make it appear for all my locomotives. Some have it, some don't.? If I copy the tags into the XML files will JMRI update the information or is there something else I need to do to activate the updating of this information?? ? ? ? ?

Snippet from an Roster XML.

Yes, once you enable the "Enable frames" setting, you can access panels via either URL, the /panel or /frame?

Our club had a similar problem on two of the six tablets we use for glass panels about two or three months ago. Maybe this was concurrent with updating the JMRI version or maybe nobody noticed it earlier as those two panels each control remote portions of the eleven scale miles of dual track main line that have little switching activities.

When we compared the version numbers for the Chrome app, those two tablets had much older versions than the tablets not showing any problems. Most of our tablets were donated by members who had moved on to more trendy gadgets, so we had some "version deficit" issues that should have been noticed earlier.

Since we do not have access to the Internet at the club, it was necessary to bring them home, log onto our local WiFi router and request Google Play to do an update. Unfortunately that took most of a day, since a lot of stuff that I thought we had deleted got updated too. My fat finger skills with smartphones and tablets is mostly limited to phone calls and Engine Driver.

Both tablets work as they had been and that problem is now behind us for the time being. Our only glass panel problem now is that we have to turn them off during Open House sessions, since stray fingers seem to invade us from time-to-time.

This experience is anecdotal from what I can tell, but there may be some value in sharing it.

Steve,

Hi Bob,

The JMRI web server has two methods of showing panels, the "frame" server and the "panel" server.

The panel server at /panel is the newer, more efficient method, as it draws the panel client-side and only sends state changes back and forth. Updates are immediate. This is highly recommended if it works for you. It requires WebSocket support on your devices.
The frame server at /frame actually sends a "screen capture" of the panel image, and tries to process mouse clicks based on position. Updates and refreshes are subject to a timer. This also works with some JMRI windows in addition to panel windows.

On old devices, there may be no WebSocket support (check?). If that is the case, you must change the Web Server Preferences to "Enable frames" and use the /frame server. That sounds like your situation.

I have been using the control panel editor panels for years now to display on tablets browsing my web server. I have not had an op session for a year but that changes tomorrow night. I was checking out the electronics and noticed the web pages on the tablets are not refreshing when signals and turnouts change.

It got me back to checking preferences and I see a 5 second refresh under frame server, but it is grayed out. What is the difference between frame server and web server in JMRI? Which should I be using to update my local panels? I was using the Android browser. Is another browser better?

Greg, glad it worked well for you. And thanks for the kind words.

Mano:

From the JMRI start screen select Edit, Preferences, Defaults. Make sure nothing is set to Internal.

Hi to all.
Start again. My PC burned and I lost all my work. I had everything Ok. Bachmann, Kato, Athearn, BLI, even MTH DCS decoder and Engine Driver included.

Micheal,
The web server has no restrictions on where a client is, so if the client can reach the network, it can see the panel pages.
So to me, your question is a security one. How can I give a remote computer access to my railroad network?
Do you have a dedicated computer on your railroad network your dispatcher could use? If so, I'd recommend you set up a remote control mechanism. I have had great results using Chrome Remote Desktop. I've also used VNC and other methods.

Nelson,

Thanks for letting both groups know.

java.lang.noSuchMethodError:

David, that error is most likely due to an old .jar file. You need to remove or rename the JMRI program folder, then extract again. On my image, that folder is /home/pi/JMRI

David, it does not appear that you used my image. My instructions assumed that you did. For example, my image does include setting up the samba shares.
Perhaps you can try my image on a new sd card.
