Grails未在视图中使用查询缓存

Question

I've found an odd issue regarding the query cache in grails and where it's called. I've tested this several times and got the same result.

Problem: The bellow view\\gsp code hits the database every time even though i have cache:true on.

 <g:select name="foo.thing.id" in="${Thing.findAll([cache:true])}" value="${foo.thing?.id}" />

Workaround: Pushing the query call into the controller respects the cache:true argument and it now stops hitting the database on every page load.

Controller:

def doStuff = {
  def things = Thing.findAll([cache:true]);
  return ['things':things]
}

View:

<g:select name="foo.thing.id" in="${things}" value="${foo.thing?.id}" />

I'm using Grails 1.3.7 with the following config....

hibernate {
    cache.use_second_level_cache=true
    cache.use_query_cache=true
    cache.provider_class='org.hibernate.cache.EhCacheProvider'
}

Has anyone else seen this or can describe to me why it would work differently?

我不确定为什么它不起作用，但这是Grails，而不是PHP-不要在视图中进行数据库访问。
