Placement in context
The action will not be published to the context until the whole tag is evaluated, meaning that inside the body of the tag, the action cannot be accessed, For example:
<s:action var="myAction" name="MyAction" namespace="/"> Is "myAction" null inside the tag? <s:property value="#myAction == null" /> </s:action> Is "myAction" null outside the tag? <s:property value="#myAction == null" />
Will print:
Is "myAction" null inside the tag? true
Is "myAction" null outside the tag? false

Another example:
<div>This will call the execute Method of /test/test.action</div>
<s:action id="myAction" name="test" namespace="/test" flush="false" executeResult="false" />
<div>If the test action has a getPropValue() method the result can be used</div>
<s:property value="#myAction.propValue" />
