hi anna,
the <map:act> containers form kind of scopes. as illustrated by neil, you
have to reference variables from outer 'scopes' via a corresponding 'path'
expression. that whole issue is a bit... dunno. but that's one reason not to
use actions.
contrived example:
...
<map:act type="act1"> <!-- returns a parameter 'foo' -->
<map:act type="act2"> <!-- returns a parameter 'bar' -->
<map:parameter name="foo" value="{foo}"/>
<map:redirect-to uri="{../foo}{bar}"/>
</map:act>
</map:act>
...
an important one to note here is act2's parameter 'foo'; since it's a
parameter to act2 it's not in act2's 'scope', even though the placement of
the <map:parameter> might suggest so. thus the reference is {foo} and not
{../foo}; just think of it as a call from within act1's scope: act2(foo:
{foo})
this is in contrast to the <map:redirect-to>, which is inside act2's scope.
so you have to reference the parent scope for 'foo' and the current scope
for 'bar'.
regarding error flagging there are several possibilities; if you stay in the
same pipeline (no redirects, etc.) you can use request attributes. when
redirecting or similar you could pass an error code or message as request
parameter(s), e.g. <map:redirect-to uri="cocoon:/handle-my-err?fail=act1"/>.
the last resort would be setting a session attribute.
