Cocoon binding for multivaluefield (multi select combo box)
Hi ,
I am trying to read values from a multivaluefield (multi select combo
box) from a cocoon form and use cocoon form binding to extract the
values.
My intent is to create an xml file from the data that has been selected
in the form.
I have tried all variation of cocoon form binding to get the data , but
not able to do so.
I am able to successfully read the value of a single select drop down
box, by using " <value id="searchFields" path="@searchFields" />" , but
not able to get values for multi select combo box.
I have tried the following:
1. ) I have tried using repeaters but that give a class cast exception.
at form.save method
<?xml version="1.0" encoding="utf-8"?>
<context path="/content"
xmlns="http://apache.org/cocoon/forms/1.0#binding">
<repeater id="searchFields" parent-path="." row-path="searchFields">
<identity>
<value id="name" path="@id" />
</identity>
<on-bind>
<value id="name" path="@id" />
</on-bind>
<on-insert-row>
<insert-node>
<entry name="" />
</insert-node>
</on-insert-row>
</repeater>
</context>
========================================================================
2. ) later I tried using only <value id="searchFields"
path="@searchFields" />, with this I am not getting any exceptions as
such but I am not able to get the values of the selected combo box.
========================================================================
3)
I also tried using aggregator, with this I am not getting any exceptions
as such but I am not able to get the values of the selected combo box.
<aggregate id="searchFields" parent-path="." row-path="searchFields">
<value id="value" path="@value" />
</aggregate>
========================================================================
My definition file is as below:
<multivaluefield id="searchFields">
<datatype base="string" />
<selection-list src="cocoon:/select-search-fields" dynamic="true"
/>
</multivaluefield>>
Can any one please throw some pointers what I can do to get the value
from a multivaluefield or let me know where I am going wrong
Thanks in advance.
Regards,
Moin

I thought there was a multivaluefield binding... yes, there is: check
the javadoc of the class MultiValueJXPathBindingBuilder for more info.
BTW, if the default bindings don't suffice, it is always possible to
write some custom code (eg. using the fb:javascript binding) to do the
binding for you.
