converting FlowApp to new FOM
Hi All,
I am in the process of converting a flow app written for Cocoon2.1RC1
to the new FOM.
The first problem I face is with the Request Object.
My helper Java Classes have been written to take an
org.apache.cocoon.environment.Request Object, but now my flowscripts
are not able to pass this anymore.
public interface Form {
/**
* Update the Form from the incoming Request Parameters
* @param request Cocoon Request
*/
public void populate (org.apache.cocoon.environment.Request request);
// snip
}
The only methods of Request that my Classes call are to do with getting
request parameters.
Is it safe to just convert these classes to use the
org.apache.cocoon.components.flow.javascript.fom.FOM_Cocoon.FOM_Request
and call methods like public String jsFunction_getParameter(String
name) instead?
Or do I need a different approach?
thanks for any help
regards Jeremy

Thanks Sylvain
I see you are absolutely right .... on my first glance at the code it
appeared to me that FOM_Cocoon.getRequest returned a FOM_Request ....
thanks for clearing that up.

Yep. Furthermore, you don't have to "unwrap" the request, since
FOM_Cocoon provides a getRequest() method that gives access to the
_real_ o.a.c.environment.Request object.

I just converted all my classes to use the
org.apache.cocoon.components.flow.javascript.fom.FOM_Cocoon.FOM_Request.
jsFunction_getParameter (String name) method, and they appear to be
working.
Would it be 'safer' to pass the FOM_Cocoon object itself, and unwrap
the org.apache.cocoon.environment.Request from it as Ugo appears to
have done?
Thanks

In the archives I found this:

and this should do it:

I tried that, and got this error:
"file:/Library/Tomcat/webapps/cocoon/editor/flow/Editor.js", line 189:
Cannot convert
org.apache.cocoon.components.flow.javascript.fom.FOM_Cocoon$FOM_Request@
a14cd1 to org.apache.cocoon.environment.Request

Jeremy,
I've never tried it but if I understood Chris correctly you can call the
method
form.populate( cocoon.request);
in your flow, and object of the type
org.apache.cocoon.environment.Request is available in your java class
HTH
Cheers,
Reinhard
