System Import Set Load data page is blank if data source name contains ${ without the closing } bracket

Page create_import_set.do will be blank if any data source names contain ${ without a closing bracket }.

The localhost will show an error similar to the following example:
> Caused by: org.xml.sax.SAXException: Runtime Exception: org.apache.commons.jelly.JellyException: null:-1:-1: Missing '}' character at the end of expression: ${ test
org.apache.commons.jelly.JellyException: null:-1:-1: Missing '}' character at the end of expression: ${ test

 

1. Go to create_import_set.do.

2. Create a new data source with the name "${    test" and click Submit.

3. Navigate to System Import > Load Data.

   A blank page displays.

 

Search for and remove instances of ${ from any data source names.
