refresh widgets in different forms, possible?

[greyelf99]

Hi, ok so I used to have an interface all in one form and am trying to convert it to a more sophisiticated layout. I now have 4 layoutUnits in the page, each has its own form. The idea is to do something in each layoutunit (except the first one) then move on to the next one, like steps.

My main problem is after uploading files in the third layoutUnit I can't update the h:selectOneListbox values in the last layoutUnit. When the page loads the listbox is empty, but when files are uploaded the listbox method #{uploadMethod.listValue} would theoretically return some values to display in the listbox - I just can't get that method to run and refresh the listBox again. I've tried merging those two layoutunits into a single form then refreshing the page after uploading files to update the listbox, with no success.

Is there a way to have a button in layoutunit 3 that refreshes the listbox in layoutunit 4? My other issue is I want to extend this to having a commandButton in each layout that enabled the widgets in the next layout when clicked. Unless of course widgets in separate forms simply don't interact this way, which I'm suspecting.

Sorry for the long post, any obvious tips would be appreciated, I'm fairly new to JSF+PF

i am still not sure what you exactly need, but you can of course update elements within another form
dont' forget to use absolute names if they are inside another naming container like form

example:

Code: Select all

<form id="step1">
		<p:commandButton value="Continue" update="@form step2:filelist"/>
	</form>

	<form id="step2">
		<h:selectOneListbox id="filelist" value="#{uploadMethod.mainFile}"
			size="5">
			<f:selectItems value="#{uploadMethod.listValue}" var="lst"
				itemLabel="#{lst.listLabel}" itemValue="#{lst.listValue}" />
		</h:selectOneListbox>
	</form>

Or JSF2 way;

Code: Select all

<p:commandButton value="Continue" update="@form :step2:filelist"/

Thanks both of you, very helpful trick to know!
