uiNode_t* UI_GetNodeFromExpression	(	uiAction_t *	expression,

	)

Get a node and a property from an expression.

Parameters:

	expression	Expression tree to analyse
	context	Call context
[out]	property	A node property

Returns:

A node (else NULL, if no node found) and a property (else NULL if no/wrong property defined)

Returns:

A string, else an empty string

Todo:

this should not work very well, because too much va are used then we should locally cache values, or manage a temporary string structure

Todo:

should we add a delta?

Read a value from the stream and init an action with it.

Returns:

An initialized action else NULL

Todo:

when it is possible, we must check range of param id

Todo:

We MUST remove the OLD code as fast as possible

Todo:

use a better check - e.g. Com_ParseValue with V_INT or V_FLOAT
