Rider - NPE when switching between design / source view in Rider

 Description  « Hide
This may be a bit hard to reproduce. But when I switch between source / design view (without changing anything) then I can get a NPE from Eclipse.

It is as if I put the "cursor" and select an EIP pattern in a route or its because I put the cursor on a attribute in the "properties" panel.
But try selecting and / or change cursor position in the properties panel.

The NPE happens only when I click the "Design" tab.

I am using the updated plugin from today. I just updated the plugin about 30-60 min ago.

Seems this has come back again; have seen it when switching between camel editors between design / XML view

see this related issue btw http://fusesource.com/issues/browse/ECLIPSE-107 seems to be the same stack trace/issue - maybe just another way to cause the same issue

Unable to reproduce that. Keep it open for a while but if it doesn't occur another time then please close it.
