[CFORM] how to repopulate repeater with Bean[] in on-value-change event?
hi everyone, I'm trying to get some forms help/best practices.
I have a form that shows a table; each row in the table is generated
from a bean via the form definition/binding at the bottom of this
post. I want to re-populate the table with new beans when an
on-value-changed event is fired. Is there a way to regenerate the
repeater rows from new beans in java?
I am able to get the new beans in an array(same as the initial form
load), but don't know how I can re-populate them in the repeater.
I have tried things like the following, and I'm getting some output,
but I don't see where I can do thiings like set the id of the Field
object so the form reads it in correctly and puts it into the correct
columns in the table. And the output looks like an array of Nodes:
[Lorg/w3c/dom.Node;@1e64a3b.
Is there a way I can generate the repeater object from the same xml I
use to define the binding? Am I even going about this the right way?
thanks!

Code I've tried without success:
Repeater accounts =
(Repeater)event.getSourceWidget().getForm().lookupWidget("accountList");
accounts.clear();
Repeater.RepeaterRow rr = accounts.addRow();
FieldDefinition fd = new FieldDefinition();
Field accountNameField = new Field();
accountNameField.setValue("accountval");
rr.addChild(accountNameField);
Working Form Binding:
<fb:class id="accountList-class">
<fb:simple-repeater id="accountList" parent-path="."
row-path="accountList" delete-parent-if-empty="true">
<fb:new id="account-class"/>
</fb:simple-repeater>
</fb:class>
<fb:class id="account-class">
<fb:group id="account" path=".">
<fb:value id="displayPath" path="displayPath"/>
<fb:value id="objectClass" path="objectClass"/>
<fb:value id="key" path="key"/>
</fb:group>
</fb:class>
<fb:new id="accountList-class"/>
Working Form Definition:
<!-- account list -->
<fd:class id="accountList-class">
<fd:widgets>
<fd:repeater id="accountList">
<fd:widgets>
<!-- inline widget definitions from accountlist-class -->
<fd:new id="account-class"/>
</fd:widgets>
</fd:repeater>
</fd:widgets>
</fd:class>
<!-- an account -->
<fd:class id="account-class">
<fd:widgets>
<!-- FIXME: doesn't work if there's not an enclosing group -->
<fd:group id="account">
<fd:widgets>
<fd:output id="displayPath">
<fd:datatype base="string"/>
</fd:output>
<fd:output id="objectClass">
<fd:datatype base="string"/>
</fd:output>
<fd:output id="key">
<fd:datatype base="string"/>
</fd:output>
</fd:widgets>
</fd:group>
</fd:widgets>
</fd:class>
<!-- a list of acount lists -->
<fd:class id="accountLists-class">
<fd:widgets>
<!-- FIXME: doesn't work if there's not an enclosing group -->
<fd:group id="accountLists">
<fd:widgets>
<fd:repeater id="accountLists">
<fd:widgets>
<fd:new id="accountList-class"/>
</fd:widgets>
</fd:repeater>
</fd:widgets>
</fd:group>
</fd:widgets>
</fd:class>
<!-- the top-level tasks -->
<fd:new id="accountList-class"/>

Re: [CFORM] how to repopulate repeater with Bean[] in on-value-change event?
Posted by Dan Ochs <da...@gmail.com>.
I have it working now. My misunderstanding was that I had to rebuild
the entire repeater row myself. But it looks like all I needed to do
was clear the repeater, then add a row. The addition of the row gave
me back an empty RepeaterRow with all of objects according to the XML
definition. The working code looks something like the following:
(Repeater)event.getSourceWidget().getForm().lookupWidget("accountList");
accounts.clear();
Repeater.RepeaterRow rr = accounts.addRow();
Group accountGroup = (Group)rr.getChild("account");
Widget accountNameField = accountGroup.getChild("displayPath");
accountNameField.setValue("accountval");
