Data Point Details No Graph - Unlicensed Module - How to Register License?

[Pedro]

Ever since I upgraded to core 2.7.10 none of the charts work on any of the pages I've tested:

• data_point_details.shtm
• point_details.shtm
• watch_list.shtm
• graphical views.shtm

I cleared the cache on both Firefox 45 and Chromium 48. The module versions in ma.log match the modules page, namely:

Loading module 'graphicalViews', v1.6.5
Loading module 'dataPointDetailsView', v1.0.5
Loading module 'watchlists', v1.7.4
Loading module 'dashboards', v1.1.3 
Loading module 'mangoApi', v1.1.5

Typical ma.log entry:

Hi Pedro,

Someone else had a similar issue. They resolved it by moving back to the 1.0.14 jar for jfree chart. Does this resolve your issue?

[Pedro]

How exactly do I move back to jfree chart?
And are you implying that some people don't have this issue?

[phildunlap]

I don't have this issue, for instance. I haven't cornered this bug to investigate it, only vicariously.

That client reported they had definitely not overridden classes and that swapping the old JAR in fixed their issue. I will email you a copy, Pedro.

You would remove the 1.0.19 JAR from Mango/lib and place the 1.0.14 JAR in its place.

[Pedro]

Thanks. I saved mango/lib/jfreechart-1.0.14.jar and moved jfreechart-1.0.19.jar to another directory, then restarted Mango. Now the charts are working again. Let me know if you need more information from my ma.log file.

In case it's relevant, I only tested this on Linux browsers, and the Mango server is Ubuntu.

[phildunlap]

Thanks for the update Pedro, glad that resolved it!

If you can check your ma.log and you feel there is something relevant, I would certainly appreciate seeing it. I think that stack trace is the same as the other I saw, and it is bizarre because that method really appears to exist in the class signature. I wonder what version of Java you're using. Perhaps it could also be useful if you wanted to respond to the email I sent you my .14 jar with your .19 (renamed so as to avoid getting bounced by email filters).

[Pedro]

Phillip, thanks for addressing this problem. I sent an email with a more detailed error log. I just remembered that I had not deleted the mango/work directory after updating. Is this done by the built-in upgrade process, or do I still have to delete it manually? It makes sense to add it to the update function. I wonder if that would cause this problem. If so, that may explain why not everyone received that error.

[phildunlap]

It is done by the built-in process, done in the upgrade shell script. Also, that doesn't feel to me like an error that would be caused by a stale JSP. Jfree charts renders everything on the server and returns only an image, and look how nestled the call stack is into the JFree code. I don't rule it out, though.
