Hi Dejan,
Do you get any error messages in the cocoon logs (/cocoon/web-inf/logs)
? A few ideas where it might go wrong:
- the list is not loaded correctly
(extensions/project-specific/createNodeList)
- myDropDownWidget is null
I assume everything works ok once you comment the rule below ?

Greetings,
We're having some difficulties with javascript events in BE template and any
help would be appreciated.
We have input field and dropdown list in our BE template. What we're trying to do is to dynamically fill
dropdown list once the input field is filled. We've tried the following rule:
<rule for="/document/page/myInputField">
<events>
<on-value-changed>
<javascript>
var list = "cocoon://extensions/project-specific/createNodeList";
var rootKey=event.source.getValue();
var myDropDownWidget=lookupWidget(event.source,"/document/page/myDropDown");
if (rootKey != null) {
myDropDownWidget.setSelectionList(list + "/" + rootKey);
} else {
myDropDownWidget.setSelectionList(new Packages.org.apache.cocoon.forms.datatype.EmptySelectionList("Enter URL
first..."));
}
myDropDownWidget.value = null;
</javascript>
</on-value-changed>
</events>
</rule>
The idea is to use the URL from myInputField, fetch that document, transform it
to node list and fill the myDropDown.
Our code is based on [1].
When we try to edit the page in CMS all we get is blank page.
Can you tell us what are we doing wrong?
