I have a dynamically created form which I then access from flowscript
var qit = newForm.getWidget().getChildren();
if (qit != null) {
while ( qit.hasNext() ) {
fwidget = qit.next() ;
...
to get each widget. I now need to pre-select some values for
all of the multi-value widgets. (Note that the widget below has a
datatype of string).
Approach 1 is what I *think* is correct; Approach 2 I know is
wrong but it does confirm that the widget I am accessing is
a MultiValueField.
Any ideas as to how to make this work properly?
Thanks
Derek
(Side note: if I omit this step, the rest of the form displays
as expected, and values for other widget types are set OK.)
Approach 1:
var values = java.lang.reflect.Array.newInstance(java.lang.String, 10);
values[0] = "Option 1";
fwidget.setValue(values); //NB also tried fwidget.setValues(values);
Result 1:
java.lang.NullPointerException

org.apache.cocoon.forms.formmodel.MultiValueField.setValues(MultiValueField.java:190)
at
org.apache.cocoon.forms.formmodel.MultiValueField.setValue(MultiValueField.java:180)
...
Approach 2:
fwidget.setValue("Option 1");
Result 2:
java.lang.RuntimeException: Cannot set value of field "q-25--6" with an object
of type java.lang.String
