Hi
I've been building up a layout editor panel, adding NX routing and signal masts and have come up against "Connectivity error when searching turnouts in Block CrossoverABSlipBlock" errors when the panel is loaded. I've uploaded the panel - /g/jmriusers/files/ProblemsBeingWorkedOn/Andy%20Brown%20-%20161045/MavinsHills-layoutPanel-19.xml

I'm running JMRI 4.18 on Ubuntu 19.10 using java 11.0.5

The error is connected with a double slip which has the offending block. I've tried deleting the slip and re-adding, but get the same error as soon as I connect up the 'A' (blue connector) leg of the slip. I've tried deleting the paths (menu option under Tables-Blocks) and saving the panel, but no change.

I looked at the xml to try and understand what is going on, but am not sure how to interpret the error message to get very far. The one thing I did see that looked odd to me (but may be perfectly ok) was the following block definition which seemed to have 2 entries with the same 'todir' and 'fromdir' (highlighted)

??? <block systemName="IB:AUTO:0007" length="0.0" curve="0">
????? <systemName>IB:AUTO:0007</systemName>
????? <userName>CrossoverABSlipBlock</userName>
????? <permissive>no</permissive>
????? <occupancysensor>TOTI-Crossover-AB-Inner</occupancysensor>
????? <path todir="128" fromdir="64" block="IB:AUTO:0005" />
????? <path todir="16" fromdir="32" block="IB:AUTO:0008" />
????? <path todir="64" fromdir="128" block="IB:AUTO:0014" />
????? <path todir="128" fromdir="64" block="IB:AUTO:0029" />
??? </block>

I must admit to being at a complete loss as to what is wrong!

The full startup log is shown below. Any help gratefully received.

Thanks
Andy

Thanks Dave.
Like you say, that method gets rid of the errors, and it shouldn't be a problem on the layout, as that section is relatively short anyway.

I was keen to get rid of the errors as I've been trying to understand another problem with JMRI 'hanging' (I had to kill the process, and even reboot once) when I tried to add signal masts. There's obviously a memory leak somewhere with the java version I'm using as I could see the memory used cranking up (3, 4, 5, 6...GB), with one of the CPUs maxed out. Unfortunately I've not been able to re-create the scenario consistently. I did manage to add the signal masts with the aid of a java 8 version, although that failed when I tried to open the Tables.... There were no errors or messages logged to the console when this was going on, so I've not much to go on at the moment.

I'll post more details if I manage to get some consistency on that problem.

PS I wasn't quite sure what you meant by "custom components".

Connectivity error when searching turnouts in Block?

This is caused by an?LayoutTrack object?that says that it's connected to a track segment… but the track segment doesn't?says?that it's connected to the LayoutTrack object.
(The error should tell you what track segment and LayoutTrack object are not connected properly… but it doesn't. I can fix that. Another TODO in the Queue… ;-)

If you want to send me your layout file I can track it down. (it may just be a bug… in which case I'll add fixing it to my queue… ;-)

Found the bug! In LayoutSlip.getLayoutConnectivity() the DOUBLE_SLIP is limiting BD instead of BC:

This line (≈1847):

See?:?LayoutEditor:Fix Connectivity error when searching turnouts in Block

Thanks George, I'll keep an eye out for the fix and try it out.
Andy

Hi George
I've tried JMRI.4.19.2+R2d508f8 and the Connectivity errors I was getting have now gone away, so that fix looks good! Great job.

(These errors had come back again after making other panel changes, so I'm glad that they're no longer showing, as they could mask 'real' errors.)

Thanks for the change - a good start for 2020!
Andy
