Docs on which is the preferred variable reference

[Greg Huber]

I seem to be doing a lot of references in my jsp's

eg

<s:set var="uuId" value="getUuId()" />

<s:hidden id="bean_%{#attr.uuId}" name="bean.somevalue%{#uuId}" />
ie %{#uuId} or %{#attr.uuId}

<s:property value="getUuId()" />
<s:property value="uuId" />
<s:property value="#uuId" />
<s:property value="#attr.uuId" />
${uuId}

Is there anywhere that explains which is best to use to reduce the overhead?

Looking at the source, there seems alot of checking with the get and #
adding and removing etc.

Cheers Greg
