[CForms] booleanfield, on-value-change => display form fields
I know how to display form fields depending on an option selected in a
dropdown list. But if I try to do the same using a booleanfield I get a
ClassCastException.
Anyone there who can explain me or give some code examples about
displaying form fields after checking a checkbox?
Many thanks!

This was why I asked for the stacktrace. Maybe it is not even related to
CForms. I will show a sample tomorrow though.

I promised something, but did not make it to send it here. So somewhat
late here is my example:
in form definition:
<fd:booleanfield id="newAddressKnown">
<fd:label><i18n:text key="newAddressKnown"/></fd:label>
<fd:on-value-changed>
<javascript>
var widget = event.source;
var stringWidget =
event.source.parent.getChild("newAddressKnownString");
stringWidget.value = new java.lang.String(widget.value);
</javascript>
</fd:on-value-changed>
</fd:booleanfield>
<fd:output id="newAddressKnownString">
<fd:datatype base="string"/>
</fd:output>
<fd:union id="newAddress" case="newAddressKnownString">
<fd:widgets>
<fd:struct id="true">
<fd:widgets>
... the optional widgets ...
</fd:widgets>
</fd:struct>
</fd:widgets>
</fd:union>
in form template:
<ft:widget id="newAddressKnown">
<fi:styling submit-on-change="true"/>
</ft:widget>
<ft:union id="newAddress">
<ft:case id="true">
<ft:struct id="true">
... the optional widgets ...
</ft:struct>
</ft:case>
</ft:union>
Hope it helps. If someone can integrate it into the Cocoon samples, I
would be happy to commit it.

I've done it like this.

Trying it in different ways I get ClassCastExceptions all the time. I'm
looking forward for a running code snipped.
Thanks for your help, Joerg!

A boolean field should also be submit-on-change-able. This means adding
the following code snippet to your template should be part I:
<ft:widget id="aBooleanField">
<fi:styling submit-on-change="true"/>
</ft:widget>

Don't know about this sample, but it should be similar. Referencing the
boolean field as case widget should work IIRC. I have done it myself, I
could have a look at latest at monday. The rest should be the same like
the selection list sample.

Hi Joerg,
I'm convinced I did it in a wrong way. But I'm still trying to solve my
problem by trial and error principle. Could you help me, please?
I need a form that displays a couple of form fields. One field is a
check box (booleanfield). If that box is checked I have to display some
additional form fields beneath that check box.
How can I solve it using unions, structs and classes? I'm using the
jx-macro sample style for my forms of Cocoon 2.1.6. This example shows
what I want to do. But a selections-list is used instead of a booleanfield.
Thanks for any help.

Can you send the beginning of the stack trace?
