Hello all,
my goal is to create something like BeanEditForm, but the underlying data is
not a Java Bean but a an XML tree (org.jdom.Element). I found out that the
core component being responsible for the field editing is PropertyEditor. My
idea is to use PropertyEditor standalone.
<t:form>
<t:propertyEditor id="propertyEditor" property="propertyName"
object="xmlData" model="myModel" overrides="this" />
</t:form>
Within the page class I customize myModel in the following way
// create empty model
myModel = beanModelSource.createEditModel(Object.class, messages);
// add xml attributes with XML specific Conduit implementation
myModel.add("myattr", new PropertyConduitXPathImpl(...));
The following problem occurs during rendering:
java.lang.IllegalArgumentException: Parameter overrideMessages was null.

My question is: can PropertyEditor be used standalone? How can I initialize
a PropertyOverrides object in the same way as BeanEditor/BeanEditForm does?
What else can I do to avoid the above exception?
I appreciate your help,
Lothar
