Logic Tags
Tag variable

This tag stores an editable shared variable using the key and value supplied in the tag attributes. This tag can also be used inside the collection tag, in which case the key attribute is not necessary and the name value pairs will be stored directly in the parent collection. The key attribute is required otherwise. It is stored in Portlet Request scope by default. This variable can be used in attribute value replacement or with the value tag.

Example:
<pt:logic.variable pt:key="test" pt:value="my value"/>
would store the value 'my value' as an editable shared variable using the key 'test'.

<pt:logic.collection pt:key="teststringcollection">
<pt:logic.variable pt:value="my string data"/>
<pt:logic.variable pt:value="my other string data"/>
</pt:logic.collection>
