Revision 1747349

A patch from Nameet Jain for "CMS throws error on clicking Find button" https://issues.apache.org/jira/browse/OFBIZ-7104

Steps to regenerate
1. Open the content app
2.  Click the CMS menu or use the link 
       https://localhost:8443/content/control/CMSContentFind
3. Click on Find submenu or use link
      https://localhost:8443/content/control/AdminSearch

The error is due to missing content index. We can improve the error message to guide user to index the content first. ContentErrorUiLabels.xml
