JIRA Bar Chart Plugin cannot be saved in Confluence

[Hans-Hermann Hunfeld]

Today an internal customer reported that he couldn t add a bar chart diagram to a Confluence page. It tooks me a while to understand that the plugin is initially hosted by JIRA but can be used in Confluence as well.

The initial configuration of the plugin and its settings works fine, also the preview shows the expected behavior/result but trying to save is simply not possible as the save button is greyed out:

Tried also shortcuts for saving but the page seems to be inrespondive...

Any ideas? We re running JIRA 6.2.5 and Confluence 5.5, Bar Chart is v. 2.5.2

I've created a bug report here: https://tngtech-oss.atlassian.net/browse/JBCP-39

We try to fix the Barcharts plugin as soon as we have time for that. As the plugin is open source, we of course invite everyone to contribute :-)
