s:selectItems inside a h:selectManyCheckbox

[giunad]

hi

I'm seeing a strange behaviour of s:selectItems inside a h:selectManyCheckbox

in detail there is a form

<a:form id="idForm" ajaxRendered="true">

A<h:outputText id="rawList" value="#{myForm.selectedTags}"/>

B<h:selectManyCheckbox id="boxList" value="#{myForm.todelTags}" layout="pageDirection">
   <s:selectItems value="#{myForm.selectedTags}" var="_tag" label="#{_tag}"/>
</h:selectManyCheckbox>

<a:commandButton id="delete" value="delete" action="#{myForm.doDeleteTag}" reRender="boxList, rawList" />

</a:form>

doDeleteTag code is

public void doDeleteTag() {
        selectedTags.removeAll(todelTags);
        todelTags = null;
        todelTags = new ArrayList<String>();
}

everything is very simple:
there is a list of tags. every tag has a checkbox (point A)
user can select several checkboxes and delete them.

after delete, the list is re-rendered to show the new list

the problem is that after user clicks on commandButton, boxList is the same as before. no change.

as test, I added an h:outputText with same value (point B).
rawList works correctly.

in few words

before I click I see:

A[tag1, tag2, tag3]

B

checkbox tag1

checkbox tag2

checkbox tag3

suppose I select tag2 and click,
now I see:

A[tag1, tag3] <--correct!

B

checkbox tag1

checkbox tag2 <--why??

checkbox tag3

what's wrong?????
why checkbox tag2 is still there??

thanks for any help.

Hi,

From my memories the lifecycle is something like that :

• restore view phase : component initialized with the model values


• invoke application : model values modified.


• render response : it checked the equality with the value initialized during the restore view.

At this point, the object are the same (same reference) between restore view and render response so to avoid useless treatment the component doesn't generate a new set of selectedItems from the model values and used the previous entries.

I ididn't check out but that's what I'm thinking about the UIOutput :
The output component display the right value because its internal behavior is more basic than the one of the selectitems tag.
Check if the component compute the value for each call ?

You can check my post about this problem too. No reply so far (except yours).

My problem was resvoled using a quick and dirty fix : the value atrtibute of the Selectitems component points to a method which returns a new List with the model values each time.

If someone can validate or invalidate my explanation (what is right and what is wrong) ?

thanks in advance.
