Actually tried this now ...

i replaced

  var form = new Form(...);
  form.createBinding(...);
  form.load(mybean);
  form.showForm("uri");

with

  var form = new Form(...);
  form.createBinding(...);
  form.load(mybean);
  while(true){
    cocoon.sendPageAndWait("uri", {"CocoonFormsInstance" : form.form});
    print("submitted");
    form.save(mybean);
  }

but ofcourse it doesn't exit the while loop.

How do i differentiate between the repeater action submit and the form 
submit? It also doesn't same to be executing the save properly because 
the repeater is not updating anymore after adding/removal.

Or did i not correctly unroll the loop in the first place?

well i meant here "before i messed with it and forgot all about it".

Bean is now updating fine during repeater add/remove actions.
Thanks a lot for your help Joerg.

Thanks for pointing that out.

The unrolled loop now looks like (form2 is my formobject)

--------------
var bizData = new Object();
bizData[Packages.o.a.c.f.transformation.FormsPipelineConfig.CFORMSKEY] 
       	=form2.form;
if (form2.form.locale == null){
     form2.form.locale = java.util.Locale.getDefault();
}
bizData["locale"] = form2.form.locale;

while (true){
  var result = cocoon.sendPageAndWait("uri",{"CocoonFormsInstance": 
form2.form});
  var formContext = new Packages.o.a.c.forms.FormContext(
cocoon.request, form2.form.locale);

//could not access form2.form.avalonContext for some reason
//var objectModel = 
//org.apache.cocoon.components.ContextHelper.getObjectModel(form2.form.avalonContext);
//   org.apache.cocoon.components.flow.flowHelper.setContextObject(
//objectModel, bizData);

  var finished = form2.form.process(formContext);
  //this causes an exception
  form2.binding.saveFormToModel(form2.form, campaignFormBean);
  if (finished){
     print("finished form");
     break;
  }
  print("redisplaying form");
}
-------------------

But i'm getting Exception trying to remove xpath .; Cannot modify 
property: mybean.participants; java.lang.reflect.InvocationTargetException

This happens when nodes are removed from the repeater.

I have public get and set methods for the ArrayList "participants" in 
mybean with a binding that used to work before
<fb:repeater id="participants" parent-path="." row-path="participants">

Did i step on something i shouldn't ?

regards
Jorg

The function showForm() is a bit more complex. You need at least the 
this.form.process(formContext) stuff which also returns the value 
finished for the while loop.
