-------------------------------------------

Hi [~daddywri],

I just came across this issue, when I compiled the UI using Java 8.

{code:java}
[qtp1613177633-367] WARN org.eclipse.jetty.servlet.ServletHandler - 
org.apache.jasper.JasperException: An exception occurred processing JSP page /execute.jsp
at line 148

145:             }
146:           }
147: 
148:           String error = RepositoryConnectorFactory.processConfigurationPost(threadContext,connection.getClassName(),variableContext,pageContext.getRequest().getLocale(),connection.getConfigParams());
149: 
150:           if (error != null)
151:           {

{code}

This happens only when the Repository connector is pre-selected as *Alfresco WebScript* and
tried to change the tab.

Thanks,

> Hi,
> I have been working on a new User Interface for ManifoldCF.
> This UI is based on Bootstrap, jQuery and some other opensource scripts.
> Only the index.jsp will be loaded once and other page are rendered using AJAX call, making
it more responsive and modern.
> Please find the attached screenshots.
> *Backward compatibility:*
> Since most of our tab comes from connectors, those tabs will be displayed as it is with
no immediate attention required. (see sample screenshot attached)
> *What next?*
> In future we can add Charts to our reports where ever applicable, so that it will be
more user friendly & informative for end users.
> Can make use of Web socket to notify exception or error to users as Notifications.
> *Browser compatibility*
> Has been tested with most latest browser and IE10, will try to add support for IE8 with
acceptable degradation.
> Any suggestion, concern much appreciated.
