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,
There is no way for the generator to know how xml can be generated out
of your domain object. There is no possibility to do that without
"helping" the framework. I do not know what is expected from source to
be xmlizable. I would have to look into the sources. Or even better do
it yourself - you'll get a better knowledge of how cocoon works.
