Upgrading from 4.4 to 4.10 breaks the script line:
??? self.panel = jmri.InstanceManager.configureManagerInstance().findInstance(java.lang.Class.forName("jmri.jmrit.display.layoutEditor.LayoutEditor"),0)

with
AttributeError: type object 'jmri.InstanceManager' has no attribute 'configureManagerInstance'

Is there a workaround please?

Nom: On totally unrelated software I had a recent problem when updating from a very old version directly to the latest version. The vendor recommended updating in several smaller steps i.e. 4.4 to 4.6 to 4.8 to 4.10 for example. That worked for me so might be worth a try in your case. Don't? forget too that java needs to be kept up to date. Others know which java version is needed by which jmri version.

Norm,

Several issues come to mind:

The most recent production version is 4.12, not 4.10 which had a lot of problems. Perhaps you simply had a typo?

Searching the release notes from through does not turn up any reference to 'jmri.InstanceManager' or to 'configureManagerInstance' but perhaps there was an earlier notification of 'configureManagerInstance' being depreciated and then simply disappearing between those versions.

Without some context as to what problem the quoted line from your script is trying to do, I am not able to figure out how to offer any useful options.

Maybe one of the developers will recognize something that he or she fixed in that time-frame and be able to provide better information. Otherwise, uploading your script to the Problems Being Worked On portion of the Files section would be in order. Be aware that most of us would only work with versions 4.12 or later.

For the sake of sanity, there are no more than one production version and one test version active on this computer at a time. Other group members may have reasons to keep older versions around.

Additional information that I neglected in the previous note:

The documentation found at supplies no clues as to what might or might not have been a 'configureManagerInstance' attribute for that class.

Nom,

This will return a list of layout editor panels:

lePanels = jmri.InstanceManager.getDefault(jmri.jmrit.display.PanelMenu).getLayoutEditorPanelList()
print "First panel: {}".format(lePanels[0])

Replace that line with?

making sure to keep the same indentation. ?The change is from "configureManagerInstance()" to "getDefault(jmri.ConfigureManager)"

Thanks Bob, that did the trick.? Thanks to all who answered.
Dave Sand, I love the humour.
