IntelliJ + unbound namespace in html files

[Mathew de Detrich]

I believe I am getting the same error message here (http://
groups.google.com/group/liftweb/browse_thread/thread/a8b91799604f79ad/
3ac947cbf1e70f5b?#3ac947cbf1e70f5b) where basically the index.html
files in IntelliJ (when used with Lift) complain about an unbound
namespace error when using IntelliJ's Web Facet

Just using the basic lift-basic package (Lift 2.3 with Scala 2.8.1),
in the file /src/main/webapp/templates-hidden/wizard-all.html,
IntelliJ says that 'Namespace 'wizard' is not bound. I believe this is
an issue due to the fact that the IntelliJ Web Facet plugin simply
does not detect these namespaces, obviously it needs to be reported
somewhere however I am not sure where (it might have to be fixed by
creating a 'lift' plugin for IntelliJ, it might technically not be a
'bug')

I think you're right that this is the lack of a feature instead of a
bug. I've seen at least one report that the next version of the Scala
plugin will be more Lift-aware. But I cannot confirm it.

I fixed these by binding the namespace myself. In the topmost element
of your .html file, you can add the xmlns:lift attribute. For your
wizard template, you can also add xmlns:wizard.

For example, my wizard-all template starts with:
<lift:Children xmlns:lift="http://liftweb.net" xmlns:wizard="http://
liftweb.net/wizard">

Now the resources themselves will get a red highlight, but there's an
intention auto-correct thingie which you can use to basically tell
IntelliJ to ignore the external resource (or something like that; it's
been forever since I've done it).

Alternatively, there's probably a way to disable the check entirely.

I know this works when using XHTML with no ill effect; I haven't tried
it with HTML 5.

The only annoying side effect is that the xmlns: bindings remain in
the final generated HTML. These have caused me no harm... so far.

Hope this helps,

Since this namespace stuff is specific to lift (in the sense it has nothing to do specifically with scala, but the fact that a scope containing the namespace from scala projects needs to be applied to the xhtml files) this should be probably done as a seperate lift face instead of in the scala facet. The scala facet should strictly deal with only scala related stuff, and these things are specific to the lift framework
