Reporting extension broken as of Rapidminer studio 7.501?

Hi all,

The reporting extension is a great way to build reports, so we are using this in some of our workflows.

However, a colleague of mine can run a workflow perfectly in Rapidminer studio 7.5.000 but when I tried in 7.5.001 and 7.6.000 I get the exception below.

Does anyone know how to fix this (even quick and dirty since the reporting extension hasn't seen an update in a while).

Exception: java.lang.NoClassDefFoundError
Message: Could not initialize class com.rapidminer.gui.plotter.ColorProvider

I tried restarting etc. and now it works. Strange that a class is or isn't found between runs/instances of RapidMiner...

Hope this helps someone else!

That extension hasn't been updated in many years. If you need something current, check out a similar one from Old World Computing.

Hi Thomas,

I saw their 'advanced reporting' extension, which works by entering data into an Excel sheet, which then updates the already existing charts.

What I like about the reporting extension is that it creates an HTML static report that you can easily distribute. Acchieving this in Excel is a bit more difficult.

Thanks for the tip though!
