Item9948: New Plugin API method Foswiki::Meta::registerMETA not working correctly

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Enhancement	Closed	Engine	FoswikiMeta

Foswiki::Func::registerMETA calling convention doesn't match Foswiki::Meta::registerMETA, so you get perl errors when you use it (Func wants a hashref, Meta wants a hash).

Additionally, it's impossible to register a new meta that is an array type like FILEATTACHMENT. SvenDowideit pointed out Foswiki::Query::Node and the %isArrayType hash. There is no good way to add an element to this hash, unless you use persistent perl and wait for the 2nd+ request (the first request compiles the .pm, overwriting any previous hash elements a plugin may have registered in initPlugin).

CDot and Olivier made some useful suggestions. Refactoring Foswiki::Query::Node::isArrayType and aliases into Foswiki::Meta; changing back to the old method signature, adding type => 'array' and alias => 'foo' along the way

Hi Crawford, your changes have enabled SemanticLinksPlugin to work quite well, thanks.

But the following no longer works:

ReleaseBlocker, I might get a few minutes to look at it tonight

Should be OK now.

Re-worded the bug title for release notes.

I don't see any of Crawford's checkins making it over to Release01x01. As a result SemanticLinksPlugin and perhaps others are broken on 1.1.2 but work fine on trunk.
