2 forms on one page?

Hi all,

 

I have another question:

 

Is it possible to define 2 forms on one page and that only the submitted
form is validated? 

e.g. buttonA submits formA and buttonB submits formB?

 

I have a datatable on my page with a detail pane.

The detail pane contains some fields in order to update the detail data
of the selected object (formA).

If the user selects multiple objects in the datatable, then I have to
show another form (formB) in order to update different fields at once
for the selected objects.

These fields have to be bound to different attributes of my backing bean
of course.

So if the user submits formB then the model of formA should not be
updated.

 

I want to switch the visibility of the 2 forms via javascript without a
generating new server request.

Does JSF support the above scenario (e.g. with subviews)?

Or is this a requirement that should be better processed with ajax
(which would be more complex for me)?

 

Any help is highly appreciated again

Michael

I'm not sure about pure JSF, as I haven't really used it, but this is
very easy with facelets, just put in two forms.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html
  xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core">
  <h:form id="formA">
    <h:dataTable .. />
  </h:form>
  <h:form id="formB" rendered="#{bean.somethingSelected}">
    <h:inputText .../>
    ...
  </h:form>
</html>

The whole view/subview may make this more complex in raw JSF. All your
state will be in the form (for client side state). The forms are just
normal HTML forms, so only the values in the submitted form will be
sent back, validated and updated.

Hope that helps,
-Andrew

Hi,

Looks to me like you could use the subForm component from sandbox:

HTH,
