Thanks for your input Roar.

It turns out that it seems to be a problem with using a view that has a 
timestamp field that is created from a date. If I just use the date field it 
works fine.

Subject: Re: [Geoserver-users] GetCapabilities throws error when Time Dimension 
is enabled

Hi,

The problem might be that you have a Null value within that time field.

To avoid the exception, you could try to use a different Presentation mode. To 
change it you must go into Geoserver for the given layer, and choose the tab 
Dimensions. For Presentation you could choose List to see if that helps.

If the problem is that you have a Null value, I think you could open a ticket 
in the Issue tracker.

Best regards,

Roar Brænden

I have set up a layer in Geoserver to use the Time Dimension. This layer works 
well when using in an OpenLayers map project. However when I run the 
getCapabilities command Geoserver throws an error:

This is causing a problem when trying to add these layers, as WMS, into ArcGIS.
Any ideas on what to do to fix this?
