After importing the new Spring Integration project (two existing Eclipse projects) I tried to use code assist in an XML config file using the new /integration namespace. SpringIDE then gives me a NPE stating the following:

I tried re-installing SpringIDE 2.0.2 and using a version of the SpringSource Tool Suite, but I keep getting this exception. This makes editing these config files nearly impossible. To reproduce, just open the helloWorldDemo.xml and try Ctrl-space in the endpoint-element, for example. It doesn't make a difference of the integration-namespace is the default namespace or not. Also, adding the namespace URI to the XML Catalog so it can be resolved to the local .xsd file makes no difference.
For completeness, here's my Session Data from the error's Event Details:
