Regarding your reply: " described in the "Building and running JMRI using Ant” section on that same page...":
That works (BUILD SUCCESSFUL).? HOWEVER I have no way or instruction on how to run either DecoderPro or PanelPro after it works.
When I go in Eclipse up to the "run", it ONLY shows the Maven options to run, which of course fail and crash (see above).
I don't have any documentation on how to set it up to run under the Eclipse debugger from that build on.
So total dead end at this point, unless someone can show me step by step how to do it.? Sorry about that.? I only know now to develop
"standard" Eclipse projects that the IDE sets up for me (and that was poorly documented!).

Regarding your reply: "Also, where did you get that URL?"
I did a google search on it, and that's what it returned.? Though now when I try another search, it is the right location.? Sigh..... Sorry, can't help.

The signalelements section is how Simple Signal Logic stores its configuration.

The message was saying that there were two separate definitions for logic for IH8. One was at or near line 5359; the other was probably earlier.

Could perhaps the signalelements section have been duplicated in the file?

Hi,

Getting this error when I load an older panel with the latest 4.12, or 4.10? Panel created in 4.8.

Parse error
while parsing file /C:/Users/martin/Desktop/PMRRC%20%recovery.xml
Exception: org.jdom2.input.JDOMParseException: Error on line 5359: cvc-identity-constraint.4.2.2:Duplicate key value [IH8] declared for identity constraint "signalElementName" of element "signalelements".

Deleting the lines concerning IH8 just moves the error to the next element down.

Checked the file for 'scripts' versus 'program' and every item is using program [per an earlier posting].

Please advise, and thanks,

Greg,

I use Eclipse, however I'm having some issues with the "Proton" release, but I'm able to build and run JMRI.? Contact me off list.

As to why the Maven build is not working, perhaps this is related:

which is related to:

which seems to indicate that Windows gets confused when there are spaces in the directory path for Eclipse.

George,

David Z,

I'd agree with what you say, possible, but not easy to do nor support. I
think I'd go as far as saying the many different systems and combinations of
ages would make supporting this even harder. What may works for one version
of a system may break on an older/newer version. By the time we come
covered, I suspect there would always be more combinations needing to be
fixed or added. But your bottom line of it not being likely worth the effort
for our community of developers seems reasonable.

Hi Dave,
A little late getting back to you on this subject.
OK, so it is not "automatic sensors", but "automatic blocks" that produce sensors automatically in automatic blocks.?
However the sensors are produced, I have a lot of them, but I do not know where each one is located on the layout or how to identify them on the Layout Editor panel of my layout.? I also do not know how to used them. I have sent the layout to the (Problems being worked on) folder and you made some changes/fixes for me. I have not modified the layout very much (but since removed a switch due to track derailments).?
1- If I can use those sensors some how I would like to know. Can they be used, and how do I give them a real name? Or are they useless without a real physical sensor? Or do I have to start over again with the sensors or blocks?
I believe my layout is George Layout
2- Not real sure where to add new blocks so that I can do more with the layout. Can you help with that? Maybe just give me some suggestions?
Thanks,
George

?ROBERT ROBINS Sep 17? ?#151897??

Not sure about pi-sprog but i tried both power on to sprog before activating jmri and power off until jmri active. Saw no effect either way. Sprog 3 worked fine either way? once the “track power at startup” was on. I did notice this choice is not present on digitrax and some others. I wonder if it is what the release note “fixed power issue” was about in the Sprog section??

Rob

Rob,
Please advise what version your SPROG 3 reports. I have v4.3 but nowhere do I see the option about track power at startup. I only have the (no)option for 9.6 baud.
Thanks, Bob

All of david’s points below are very true.

There are a couple places where people have added JMRI code to handle “where did it go?” errors. But it tends to be very case-by-case, because it’s not just the connection that was lost: The external hardware can be in a messy state too.

If anybody who’s having cable trouble wants to work in this area, I’d be happy to help them get started. The basic “reconnect in place” code isn’t that complicated.

But even if somebody writes that code, there’s no way that JMRI can avoid a disruption when a cable is disconnected. When that happens, the pieces can’t talk to each other until it’s fixed.

Once a connection is lost, the file handle connecting to the port is no longer valid and a new one has to be created by reopening the port. But that means that existing JMRI threads using the port need to be shut down and restarted, effectively a full restart of JMRI.

I have applications which (when running) notice the addition & removal of devices and then do the right thing accordingly.

It would be entirely possible to note (via code in JMRI application) when the connection is lost, and then have the application attempt to restart the connection automatically. You'd need to loop around the restart, because it may be a while (if ever) before the connection comes back.

Trying to notice when the underlying devices are lost and then recreated (such as Linux/macOS will do, don't know what it looks like on Windows) is also possible, but involves a bunch of code that is system specific, and Java has worked fairly hard to isolate the application programming from that system specific work, to the point of not providing all of the APIs that would make this reasonable.

So it's possible. It's also a lot of fiddly work, which would mostly serve as a workaround for faulty physical connections. It would have some value for situations where the computer is on one power circuit, and the layout on another, so JMRI could be responsive to the sudden appearance of the layout control system.

Solving this problem would probably also resolve many of the concerns that lead us to having to restart JMRI when making certain preference changes. The application could close the current connection, and then restart it again with the new configuration.


I suspect by this time the changes needed to make this all work properly will be very complex, and not a good match to the sorts of things that tend to be done by volunteers (who get to pick and choose what they're interested in working on).

Don,

The connection definition for a pair of edge connectors is “block X on panel A connects to block Y on panel B”. It is a logical connection at the block level with the blocks on different panels.

Since it is a block boundary, it is possible to assign signal masts and NX sensors to an edge connector. I have submitted a change which makes it possible to assign signal heads to an edge connector.
