This will work if the form is in session scope, but NOT if it is in request scope. the
reason being is that the form is recreated every time, and the parameterList will be
null.
what is needed is some kind of creation description in the config file - which I built
a quick version of yesterday. I don't know if the dynamic form beans are supposed to
fix this kind of issue... does anybody know? (aka when is that going to get
documented? lol)
if not I should be able tidy this stuff up a bit and submit it to somebody who can do
the proper integration.
my config xml stuff looks like this:
<form-creation-definition name="aForm">
<form-creation-property name="someProperties"
type="java.util.ArrayList"
sizeProperty="propertyCount"
childType="foo.bar.SomePropertyType">
<form-creation-property
name="subProperties"
type="java.util.Vector"
sizeProperty="someProperties[].subPropertiesSize"
childType="foo.bar.AnotherPropertyType"/>
</form-creation-property>
</form-creation-definition>
only aggravating thing is placing the size of collections into the form, so they can
(have) to be written out by <nested:hidden>s. Would be easier if either the collection
interfaces could be accessed as a bean properly (ie. getSize() instead of size() ) or
the commons output code could handle it.
