Having 357 input fields in 6 tabs. How inputs get submitted

[martinjozef]

Hello everyone.
I have this real life example where
I have 357 form inputs spread out throughout 6 tabs. there is some
ajax support used inside the tabs, and the user is free to move between the tabs freely.

My Question is.. what is happening to those inputs, does all 357 fields get submitted every time we switch between tabs, or perform ajax call to a backing bean while being inside one of the tabs?

I would hope that only the rendered tab is being submitted since the tab switching is set as "SERVER" side.
Can anyone shed some light on this.
Is is practical to have single <h:form> tag encapsulating when
we have many tabs with huge amounts of input fields.

I already know that having individual <h:form> for every tab will not save inputs to my backing bean between tab switching.

Is this efficient for large amounts of Tabs with large amount of input fields

<h:form>

<tabPanel>
 <tab>
 <ui:import src="etc" />
 </tab>

 <tab>
 <ui:import src="etc" />
 </tab>

 <tab>
 <ui:import src="etc" />
 </tab>

</tabPanel>

</h:form>

whole form per request. Does not matter, this is an Ajax or non-Ajax request.

I mean, the whole form that is rendered to the client.
if the switchType is client, it will be the whole amount of fields from h:form to /h:form

In case of "server" or "ajax", only the active tab is rendered. So, only the fields that belong to the active tab will be submitted and then processed.
