Re: latest xform
Hi,
I´ve been trying to use your example but I get an XFormException:
org.apache.cocoon.acting.XFormAction$XFormActionException: XFormAction:
missing XFormInstance [orderForm]
How do you setup your example?
/Regards Mats
ps.
We´ve developed a similar formhandling application for C2 but based on
transformers instead...but I´m very curious about the XSP approach...
ds.
/Regards Mats

you have to look at the page request before the
one you sent.
The instance will be created if you go to the xform
page the first time!!

They shouldn't...

Well, you need to specify the taglib in the cocoon.xconf otherwise
the tag should be passed. You also might want to have a look into
the java code of the page in the repository.

No, that's fine. There is no longer a central PostRegistryComponent
but a PostRegistry as a a helper class. Totally different but I kept
the name.

Do I have an old version of the XForm-example, I saw in your mail that
you´ve removed the postregistry but in my code it is still there...

The instance data is not available in the session.
Start with a fresh browser and have a look
at "tail -f cocoon.log|grep XForm"
You should see the XForm logicsheet fill the
XForm instance named [orderForm]. Then it should be available.

Well, maybe we can share some thougths...
Right now I am improving the updating of the instance.
So changes on the instance (e.g. via esql) are better handled.
This will also make the xform:selectMany work.
After that we need the validation and error reporting...
Feel free to help ;)
