Barbara,
I solved a problem like yours in a rather awkward way... but you may find it useful.
1) I wanted to choose a pipeline based on a parameter outputted by my database
operations (I use Stored Procedures, hence an output
parameter, called intStatus, was used as a status variable: 0 Ok, 1 Generic error, 2
Constraint violation, ...
2) I wanted to pop-up a Javascript dialog box or an HTML page in the same window or an
HTML page in a new window in response to SP's
status
Hence, I built a pipeline like this:
<map:match name="wildcard" pattern="clearlog-execute.html">
<map:aggregate element="page">
<map:part src="documents/general/control-parameters.xml"/>
<map:part src="cocoon:/sp-uman-clearlog.xml"/>
</map:aggregate>
<map:transform src="stylesheets/general/sp-control-html.xsl">
<map:parameter name="control-section" value="clear-log"/>
</map:transform>
<map:serialize type="html"/>
</map:match>
Where:
1) control-parameters.xml contained a list of actions to take in response to the SP's
status, like:
<spctl:control-section id="clear-log">
<spctl:control trigger="{0}">
<spctl:action href="changes.html"
target="frameChanges"/>
<spctl:window type="dialog"
</spctl:control>
<spctl:control trigger="{10}">
<spctl:window type="dialog"
message="Generic error, contact your database administrator"/>
</spctl:control>
</spctl:control-section>
2) sp-uman-clearlog.xml is a pipelin that executes an SP
3) sp-control-html.xsl is a stylesheet which executes the action triggered by the SP's
status parameter (this actions have been
detailed in control-parameters.xml). This XSLT builds a minimal HTML page to be
executed at load time
4) By the way, I need an hidden frame to use it as a callback for the action
Let's see what happens in the control flow between client and server:
Case A) the SP returns "10" in intStatus:
1) Client --> clearlog-execute.html with hidden target (say "frameCmd")
2) Server --> HTML page containing the window.alert() to the frameCmd hidden frame
executed by onLoad event
3) The user see a Javascript dialog box
Case B) the SP returns "0" in intStatus:
1) Client --> clearlog-execute.html with hidden target (say "frameCmd")
2) Server --> HTML page with a form (executed by onLoad event) with points to
"changes.html" with target "frameChanges"
Client --> changes.html with shown target frameChanges
3) The user see the changes.html page in the frameChanges frame
Ugly and a bit slow, I know... but really flexible.
