6810 (Changes to EL Node Evaluation Functions)

We've introduced three Expression Language node evaluation functions, which return a copy of the node with the evaluation state set in the following ways:

  • pre(node): the node has not yet been evaluated (replaces the now deprecated node.pre()).
  • mid(node): the node is currently being evaluated
  • post(node): the node has already been evaluated

Examples

Old:

  • I don't currently have a way to #{action (this.pre())}.
  • I currently don't have the ability to #{action (this.pre())}.

New:

  • I don't currently have a way to #{action(pre(this))}.
  • I currently don't have the ability to #{action(pre(this))}.
