selected value and immediate submits

Hi,

 

I asked this question a few months ago but I didn't get an answer. So I
try it again because I have to solve this now.

 

I have a selectOneMenu and a link beside it. When the user clicks the
link I need the selected value in my BackingBean without form
validation. The target of the link is an iframe and I don't want that
the same page with error messages is rendered in this iframe. Therefore
the immediate attribute of the link is set true.

I can't use a ValueChangeListener because this is not called with
immediate submits, right?

 

Can I use an updateActionListener and set the selected value via
javascript (see snippet and the '???')

 

Or is the usage of a component binding for the selectOneMenu the only
working alternative?

 

 

Snippet:                       

<t:selectOneMenu id="documentTypeId" forceId="true" 

     value="#{MyBean.document.attributes['documentTypeId']}">

   <f:selectItems value="#{MyBean.scoredCategories['documentType']}"/>

</t:selectOneMenu>

                        

<h:commandLink action="#{MyBean.switchHighlighting}" immediate="true"
target="zone1">

   <t:updateActionListener property="#{MyBean.selectedDocumentTypeId }"
value="????"/>

   ...

</h:commandLink>

 

Thanks in advance,

Michael

Michael,

I have the same functionality in my application. (Or rather I used to, 
before I started using subForms ;) I used the following:

<h:commandLink action="#{search.doSearch}" immediate="true">
	<h:graphicImage.../>
</h:commandLink>

<h:selectOneMenu value="#{search.searchOption}"
		 onchange="submit()" immediate="true"
		 valueChangeListener="#{search.updateSearchOption}">
	<f:selectItems.../>
</h:selectOneMenu>


And in updateSearchOption() I have this:

public void updateSearchOption(ValueChangeEvent event) {
	String newOption = (String)event.getNewValue();
	this.setSearchOption(newOption);
	...
	FacesContext context = FacesContext.getCurrentInstance();
	context.renderResponse();
}

I would go with a binding, don't know if there are other ways to do
what you need.
