I have noticed that during edit "spring-config.xml" file and after entering:
xmlns:p=" and ctrl + space
editor does not show me "p-namespace" (shown bellow) on the list:
You can see it on the attached screenshot:
Finally, I have to enter that namespace manually :-/
Is it correct behaviour?
Is it not supported namespace?
This is a side-effect because c:/p: "namespaces" do not have an associated XSD scheme. I've created http://youtrack.jetbrains.com/issue/IDEA-101723 to track this request.
You can also use "Convert to p-namespace" intention on any <property> tag to convert it to p-namespace usage, this will also create xmlns declaration automatically.
