I'm writing an action. It's definition is as follows:
public Map act(Redirector redirector, SourceResolver resolver, Map
objectModel, String source, Parameters parameters) throws Exception {
...
}
I call the action in the sitemap in a context similar to the following:
<map:match pattern="**">
<map:match pattern="*.html">
<map:act type="abc">
<map:parameter name="abc-param" value="abc-value" />
<!-- MY ACTION IS HERE -->
<map:act type="def">
<map:parameter name="def-param" value="def-value" />
</map:act>
</map:act>
</map:match>
</map:match>
I want to be able to get at sitemap variables from all context levels from
within my action. That means that in the invocation of 'def' above, I want
to be able to access {def-param}, {../abc-param}, {../../1} and
{../../../1}. As far as have been able to determine, the parameter
"Parameters parameters" of the 'act' method only contains "def-param".
Can someone point me at how to read the other parameters from within
'act'?
Define/expect another named parameter in your action, and in the sitemap
specify {../../1} or whatever as its value. e.g.
<map:act type="def">
<map:parameter name="def-param" value="def-value" />
<map:parameter name="other-param" value="{../../1}" />
</map:act>
As you have seen, only the parameters directly inside the map:act are passed
to the action. The values with {../whatever} are a sitemap notation.
Trying to lookup a value from a parent map makes no sense in the action
itself - how would it know in what context it was used, or if it was even
used inside the scope of another map? Or suppose you inserted another
action (e.g. LocaleAction) into the sitemap between the matcher and your
action - if your action relied on a specific path to the value, it would
break as it would now be looking at the wrong level...
