TabLibSpec Out Is Null (Not returned)

[Brian Saville]

This may be resolved with Grails 2 since we might not use TagLibSpec...

Currently the code in tag lib spec is this:

  def invokeTag(String name, Map params = [:], Closure body = null) {
    def tag = tagLib."$name"
    def out = (tag.maximumNumberOfParameters == 1 ? tag(params) : tag(params, body)).toString()
    reset()
    out
  }

It should be this (as some tags do not return the 'out' property at all:

  def invokeTag(String name, Map params = [:], Closure body = null) {
    def tag = tagLib."$name"
    if (tag.maximumNumberOfParameters == 1)
      tag(params)
    else
      tag(params, body)
    def out = tagLib.out.toString()
    reset()
    out
  }

If this would still be an issue in Grails 2 or it deserves a fix for the grails 1.x branch, let me know and I'll submit a pull request. Just let me know if there's another branch or something to submit it to.

There's no branch. The same code is used for both.

Pull request would be much appreciated :)
