Hi Sylvain,

that's why I'am a little bit confused about the documentation because 
model.lookupWidget("age") as well as other methods from type Widget 
doesn't work in my flowscript. I got this exception:

Original Exception: TypeError: lookupWidget is not a function. (file:/E:/container/instances/testsys/webapps/evalsys/app/flows/fillOut.js; line 13)
	at org.mozilla.javascript.NativeGlobal.constructError(NativeGlobal.java:581)
	at org.mozilla.javascript.NativeGlobal.constructError(NativeGlobal.java:541)



In the listing below you can see the part in my flowscript:

  var form = new Form("cocoon:/formDefinition/" + inquiryName);
  form.showForm("formTemplate/" + inquiryName);

  var model = form.getModel();
  print("Widget: :" + model.lookupWidget("age"));

What's wrong here?
Thank you for your help!

Stephan

                       ^^^^^^^^^^^^^^^^^^
lookupWidget is a method of the Form object, not of the model.

Hi,
after I had tried several times to iterate over a widget using 
flowscript (model.lookupWidget()) I had realized that - in my opinion - 
this is not easily possible. The problem: I don't know the id's of the 
widgets! So there are two big questions I'm having:

1)
In Java I can use .getChilds() of a ContainerWidget which returns me an 
iterator to iterate over all childs of an widget. I couldn't find such a 
method in the flowscript API. How to solve this problem? Either I need a 
length of all childs and then I can get one by one by pointing to its 
index or I need an iterator.

2.)
I didn't find a way to resolve a Widget value of type MultiValueField. 
Therefore its not possible to retrieve such values. None of "typeof" or 
"instanceof" worked correctly to determine the object type. How can I 
resolve whether it is a MultiValueField or not?

Thanks!

Stephan

Well, don't thank me, I was of little help in finding the solution ;-)

Hi Sylvain,

I have resolved my problem: I have to include the v2 Form.js and to 
change form.getModel() to form.getWidget().

Thanks.
