MongoDB Connector - stuck

[sszretter]

 I am using the latest downloads of iReports (4.02) and JasperServer CP 4.0.0 - I followed the pdf instructions on installing the plugin for the MongoDB connector to iReports which worked fine and I dropped the files in to the WEBINF folder for JasperServer.  I created a new data source fine of type MongoDB and it tested fine with the test button.

However, when I follow the steps to create a report, I click new report, wizard, and when I get to the query step I am pasting in a sample from the pdf :

{ 'collectionName':'accounts' }

If I change the collectionName to a valid name 'clients' in my case and click next, nothing happens and the next button is now grayed out.   Nothing I do will make it clickable except starting over.   SO I am unable to get past this point.

What am I doing wrong, or what can I do instead to get a report created?
