Hibernate, Woody and repeaters
I am having trouble using the result of a hibernate query in a woody
form. I'm trying to do the following:
1. Generate the bean from a hibernate mapping file using hbm2java.
2. Load the entire contents of a table using hibernate -- obj =
hs.find(queryString).
3. Use the resulting object as the form model for woody -- form.load(obj).
4. Save the (possibly) edited results -- hs.save(obj);
I think I have datatype problems but not sure how to fix them. I've
attached the flowscript code, exception text, form definition and bean
class. Any help will be GREATLY appreciated. Thanks in advance.
Joel
Here's the offending code:
var factory =
cocoon.getComponent(Packages.com.displayware.hiblib.PersistenceFactory.ROLE);
var hs = factory.createSession();
var contacts = hs.find("from User");
cocoon.log.debug("contacts.size() = " + contacts.size()); // RETURNS 1
form.load(contacts); // EXCEPTION THROWN HERE
form.showForm("useradmin-display-pipeline");
This throws the following exception:
"resource://org/apache/cocoon/woody/flow/javascript/woody2.js", line
191: Invalid JavaScript value of type org.mozilla.javascript.UniqueTag
The model I'm using for the form looks like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<wd:form xmlns:wd="http://apache.org/cocoon/woody/definition/1.0"
xmlns:i18n="http://apache.org/cocoon/i18n/2.1">
<wd:widgets>
<wd:field id="tab-state">
<wd:datatype base="string" />
</wd:field>
<wd:repeater id="contacts">
<wd:widgets>
<wd:field id="username" required="true">
<wd:label>Username</wd:label>
<wd:datatype base="string" />
</wd:field>
etc...
</wd:repeater>
<wd:repeater-action id="addcontact" action-command="add-row"
repeater="contacts">
<wd:label>Add contact</wd:label>
</wd:repeater-action>
<wd:repeater-action id="removecontacts"
action-command="delete-rows" repeater="contacts" select="select">
<wd:label>Remove selected contacts</wd:label>
</wd:repeater-action>
</wd:widgets>
</wd:form>
The bean looks like this:
package com.displayware.hiblib;
import java.io.Serializable;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;

}
public void setPhone(String phone) {

}
public String getEmail() {
return this.email;
}
public void setEmail(String email) {
this.email = email;
}
public String toString() {
return new ToStringBuilder(this)
.append("id", getId())
.toString();
}
public boolean equals(Object other) {
if ( !(other instanceof User) ) return false;
User castOther = (User) other;
return new EqualsBuilder()

}

I haven't created a binding under the (probably mistaken) assumption
that there is a default jxpath binding that maps the structure of the
form definition file to a corresponding bean -- this binding runs for
example when form.getModel() is called. So, I have been trying to use
this default binding as is, substituting the bean created by hbm2java.
In the form2bean sample, I can't even find a binding file. Do I need
one?
Yep... can't do load()/save() without a binding. From the samples
sitemap, here's the pipeline that invokes the form2bean controller:
<map:match pattern="form2bean.flow">
<map:call function="handleForm">
<map:parameter name="function" value="form2bean"/>
<map:parameter name="form-definition" value="forms/form2_model.xml"/>
<map:parameter name="bindingURI" value="forms/form2_bind_bean.xml"/>
</map:call>
</map:match>
The parameter "bindingURI" specifies the binding descriptor - so have a
look-see in forms/form2_bind_bean.xml, and you'll be well on your way!

Mark,
Glad to hear from you! Here's the form template. Basically, a cut n
paste from Hugo's sample with a few things changed. If I comment out
the form.load() in the flow, this form displays fine (albeit empty).
