How do I set fields in an arraylist from the view

[Charbel Abdul-Massih <ca...@soundbite.com>]

I have the following problem...

 

In my Backing Bean called editPhone, I have a phones property which
contains a list of PhoneNumber objects...The PhoneNumber object has a
rawValue property that is the actual phone number, and the property I'm
trying to retrieve and set...

 

In my JSF, I have the following code

 

<t:dataList value="#{editPhone.phones}" var="phone" id="phonesTable"
rowIndexVar="row">

   <h:column>               

      <h:inputText value="#{editPhone.phones[row].rawValue}" size="10"/>

   </h:column>

</t:dataList>

 

I am getting the right values back into my text boxes, but when I edit
the values on the screen and hit submit, they are not being saved back
into my bean.  What am I doing wrong?  How can I get such a scenario to
work???

 

Thanks,

Charbel

First off, you can use

<t:dataList value="#{editPhone.phones}" var="phone" id="phonesTable">
[...]
<h:inputText value="#{phone.rawValue}" size="10"/>

and dump the row index.

There's many reasons why your values might not being saved.  Here's a
couple that I can think of.

1) You're hitting a validation error somewhere on your page.  It may
not even be related to your phone list.  Add these tags to your page:

	<t:messages globalOnly="true" showDetail="true" />
	<t:messages globalOnly="false" showDetail="true" />

2) The editPhone bean is request-scoped, and thus there's no list to
work from when your form is submitted.   You can test for this problem
by making your bean session-scoped temporarily.   My preferred fix for
this situation is to use

	<t:saveState id="editPhonePhones" value="#{editPhone.phones}"/>
