I have worked around the problem by adding my bizData to the Form as an
Attribute.
We need to decide which to do ....
fix it if it is broken
update the docs with the proper technique if it does actually work
remove it from the docs if we don't want this functionality

Sorry to bug you guys about this again, but I still have no solution.
According to the docs, I am supposed to have access to BizData sent
with the sendForm function, from within CForms EventHandlers, but
still cannot work out how to do it.
I am using the CForms model in :
resource://org/apache/cocoon/forms/flow/javascript/Form.js
Form.js seems to add the bizData to the ContextObject, but I do not
see how to retrieve it.
Should I be able to do this?
Or is it a bug in the code or the docs?
Thanks for any help

Hi All
A little problem I cannot solve ...... and I cannot find any samples
tat do this ......
Part of a form I am working on has a couple of menus.
The menu called 'group' is a list of folders grabbed dynamically from
the filesystem by the flowscript that calls the form.
The menu called 'cid' is set to a list of the files in the folder
chosen in "group".
<fd:field id="group" required="true">
. . .
<fd:selection-list type="flow-jxpath" list-path="groups"
value-path="value" label-path="label" />
<fd:on-value-changed>
<javascript>
var value = event.source.value;
var cid = event.source.lookupWidget("../cid");
if (value != null) {
cid.setSelectionList(getComponentFiles(viewData.components,
value), "value", "label");
} else {
event.source.setValue(null);
cid.setSelectionList(new
Packages.org.apache.cocoon.forms.datatype.EmptySelectionList("..."));
}
cid.setValue(null);
</javascript>
</fd:on-value-changed>
</fd:field>
The function getComponentFiles needs the 'components' parameter,
which is the location of the base components folder. It needs to be
passed from a SiteMap parameter, so I have added it to the bizData:
form.showForm(screen, {groups:getComponentGroups(components),
components:components});
I am getting errors similar to this when the form attempts to load:
ReferenceError: "viewData" is not defined
I have used the "viewData" value in projects before, in earlier
versions of CForms.
I have tried several variations, but cannot work out the correct way
of getting the bizdata.
viewData.components
viewData["components"]
components
etc.
If I make 'components' a global JS variable instead of passing it as
bizData, I can access it fine, but I would prefer not to work that
way ;)
What am I doing wrong?
Thanks for any suggestions.
