Processing dynamically-created forms
Working with Cocoon 2.1.8
I am looking for examples or guides on how to post-process a form
that will have been created dynamically i.e. it won't be possible
to know in advance which fields appear or what they are called.
I know how to create such a form, but not how to "get at" the data
it will contain.
Normally, in flowscript, I would access a field value in a form with the
model.Fieldname
notation... but without knowing what those fieldnames will be, I am unsure
of how to proceed.
Any help or pointers appreciated!
Thanks
Derek

Not that I'm aware of but it's really not rocket science here. Maybe you got confused about java
widget iterator. All I meant was that you will get object implementing Iterator[1] interface so you
can use it as any other iterator in the loop.
The code sample in JS should look like:
for (var it = formmodel.children; it.hasNext(); var widget = it.next()) {
//do whatever you want with widget here
}

No, I have not. I have not used this before; is there any sample
code of how to work with the java widget iterator?
Thanks

Hi Derek,
Have you tried:
var it = model.children
Where it will hold Java iterator over widgets that model contains.

I finally managed to find the answer - its mentioned here:
http://mail-archives.apache.org/mod_mbox/cocoon-users/200708.mbox/%3C46B12CD0.60000@lojjic.net%3E
Basically you need to use:
var myWidgets = myForm.getWidget().getChildren();
So, for the record, my complete code looks like:
if (myForm.getWidget().getSubmitWidget().getId().equals("ok")) {
var it = myForm.getWidget().getChildren();
if ( it != null ) {
var fwidget = null;
var ID = null;
var val = null;
while ( it.hasNext() ) {
fwidget = it.next() ;
ID = fwidget.getId();
if ( (ID!=null) && (ID!="ok") && (ID!="cancel") && (ID!="message") ) {
val = fwidget.getValue();
if ( val!=null ) {
//process a widget that has a value...
}
}
}
}
}
HTH someone!

Hi Derek,
Thanks for reminding me. I'm just developing some Forms so I'll try my suggestion and see why it's
not working. Stay tuned.

Unfortunately, when I try:
var it = model.children;
it has an "undefined" (null) result, not an iterator.
I also tried:
var it = myform.getChildren();
but without success.
Any ideas how to get this to work? I have tried this in
different flowscripts for different forms; all have the
same problem.
Thanks

Unfortunately, when I try:
var it = model.children;
it has an "undefined" (null) result, not an iterator.
I also tried:
var it = myform.getChildren();
but without success.

different flowscripts for different forms; all have the
same problem.
Thanks
