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
regards Jeremy

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.
