Dear List,
I am trying to insert a domain object into the pipiline with control flow following a suggestion given earlier on this list:
http://www.mail-archive.com/[email protected]/msg23293.html
Suppose, I return some object from a domain class instance, like
var domainObject = com.foo.myClass.doSomething();
The domainObject has all the getters available, e.g. getName(), etc, so it acts like a regular bean.
Now, I would like insert this object in the pipeline with
cocoon.sendPage ("page", domainObject);
try:
cocoon.sendPage( "page", { "domainObject" : domainObject } );
If you pass it as you previously did your domain object is the main context. flow-attr:domainObject looks for an object "domainObject" in main context so in fact in your case it queries for /domainObject/domainObject which is incorrect
I see. I tried and indeed this gives a different result. At least, I can now see some values. The error message is now
org.apache.cocoon.ProcessingException: Exception during source resolving.: org.apache.excalibur.source.SourceException: The object type: class com.foo.DomainObject could not be serialized as a InputStream DomainObject - name: jfifiikss, id: -1977936240, author: FOO
This is caused by the class com.foo.DomainObject itself.
In the sitemap, I have
<map:match pattern="page"> <map:generate src="module:flow-attr:domainObject" /> <map:serialize type="xml" /> </map:match>
(This is just to see how it looks like.)
The result of all this is an error of the form:
org.apache.cocoon.ProcessingException: Exception during source resolving.: org.apache.excalibur.source.SourceException: The attribute: domainObject is empty
This looks obvious to me, since it is probably not clear that the domainObject in facts represents some class, defined in com.foo.myClass. So, I tried to define the DomainObject class in JavaScripy, like
function DomainObject() { } DomainObject.prototype.name;
and populate the object manually before calling cocoon.sendPage. The result is however the same.
I am using cocoon 2.1.7.
Could anyone point out in some detail how exactly I should do this.
Thanks,
