[rake@…]

Nach Aktivierung des "Measurement mode" (click auf das entsprechende Icon im Toolbar) führt ein Click in den Datalayer (Anfangspunkt einer Messung) sofort zu unten aufgeführter Exception.

Something has been changed at some point, which requires that you always select the Measurement layer before any clicks for the measurement plugin to work. That is, until the plugin is fixed.

[Hasienda]

can't see this behavior here in any of the following JOSM revision

• 716
• 1073
• 1075 (latest to date)

running on two different Debian GNU/Linux systems

@reporter: please re-open with more details, if still valid for you

[anonymous]

have tried it as well.Unfortunately the following happens Open Josm (tried 1067 and 1078) open a gpx file open "measurement" plug-in click a point where the measurement should start following error message (probably from JOSM): An unexpected execption occurred that may have come from the 'measurement' plug-in. Try to update before reporting a bug. Should the plug-in be disabled?

I run measurement plug-in 10440 and JOSM 1078 Windows XP with SP 3 Java Platform SE6 U7 then upgraded SE U10, same problems

find this a handy tool, so would appreciate if it works again,

[Hasienda]

more testing at my system, now I second problem with measurement plugin, since it doesn't crash JSOM here on Debian GNU/Linux but throws an NullPointerException at JOSM startup

for details on my latest plugin checking session see also #1734 (marked that ticked as duplicate myself)

[Hasienda]

still valid for JSOM revision 1096 (latest to date) and measurement plugin 10440 (still unchanged since my earlier tests)

Fixed in SVN.

[Hasienda]

Sorry, I don't trace the SVN content by now. At with point is/was this fix incorporated to the released revisions? At my workstation I still get this:

I'd rather say this is a variant of #1883. Try disabling usertools.

[Hasienda]

First, don't close this with worksforme as anonymous user, please - bad move.

Second, no, it's not a variant of #1883. What made you think it is? The issues are in fact completely unrelated since the problem and error description here existed unchanged (up to the java code line number) long before the code switch referenced over there.

Third, what do you expect to happen after disabling usertools? I no longer get an error on JOSM startup. I'm not impressed, since usertools doesn't work either way as does explicit re-loading on re-activation of the plugin improve anything. Again, here it's not about an issue introduced lately, not about usertools plugin.

[stoecker]

Because I wrote the code and I know that activated old plugins cause exactly that type of error.

The original report fails in MeasurementMode.java, your report fails in ToggleDialog.java. First one is in measurement plugin. Your code is in JOSM core.

When usertools is disabled it will no longer call functions wrong and thus it will not produce errors like that above.

If the problem still exists after your disabled usertools and all other plugins are updated and you restarted JOSm, then open a new bugreport with a helpful description.
