Detecting Partial Refresh

Hi all,

I have a page in which I use a partial refresh to
update selectable values in some drop-down boxes.  In
this scenario, the values in one drop-down determines
the set of possible values in another drop-down.  So,
a partial page refresh seemed an intuitive way to
handle the update of the dependent drop-down.

In addition to these drop-down boxes, there are other
components on the page, some of which need validation.
 However, I would only like to validate the components
when the form is "actually" submitted--not during the
autoSubmit of my related drop-down boxes.  Is there
any way to detect the partial page refresh during the
validation phase and prevent the validation from
occurring?  Or is there a better way to handle this?

Thanks,

--David

David,

I don't actually use Trinidad yet, so I can only point you at the
theory rather than the practice.

However, using the Tomahawk components (which I believe were based on
the Trinidad ones), this works fine:

	<sandbox:subForm id="chooseForm">
		<h:selectOneListbox
			size="10"
			value="#{bean.item}">
			<f:selectItem
				itemValue="#{bean.nullSelectItemOptionValue}"
				itemLabel="&lt;No selection&gt;" />
			<t:selectItems
				value="#{bean.itemChoiceList}"
				var="item"
				itemLabel="#{item.code} - #{item.description}"
				itemValue="#{item}" />
			<sandbox:submitOnEvent for="execute" />
		</h:selectOneListbox>
		<h:commandButton id="execute"
			value="Go!">
		</h:commandButton>
	</sandbox:subForm>

Re: Detecting Partial Refresh

Thanks for the link.

So, I wrapped my drop-down boxes in a <tr:subform> and
the other components in one as well.  Now, validation
doesn't occur on the other components, but changing
the drop-down box values no longer works.  After I
change a drop-down value, the resulting phases are:

Restore View --> Apply Request Values --> Render
Response

Why should wrapping the drop-downs in a subform cause
the Process Validations, Update Model Values and
Render Response phases to be skipped?

Thanks for your help,
