[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-2148) Support for SelectItemGroup

[Stephen Friedrich (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-2148?page=all ]

Stephen Friedrich updated JBSEAM-2148:
--------------------------------------

    Attachment: selectItems_group.patch

Here's a patch that adds these attributes to s:selectItems:
group - object to group by
groupVar - var name to store the object into
groupLabel
groupEscape
groupDisable

For now I only tested with a single example (checking the result with different values for groupDisabled and groupEscaped):

<s:selectItems value="#{aircraftTypes}" var="aircraftType" label="#{aircraftType.name}" group="#{aircraftType.manufacturer}" groupVar="manufacturer" groupLabel="#{manufacturer.name}"/>

Unfortunately neither mojarra nor Trinidad honor "escape" and "disabled" properties for SelectItemGroup:
https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=749
https://issues.apache.org/jira/browse/TRINIDAD-1140

I will have a look at Seam's unit tests and see how stuff that needs a FacesContext can be tested.
Also if this code is generally fine (implementation fixes non.-withstnding) I am going to update the docs.

> We can do something like
> <s:selectItemGroup label="#{foo.bar}">
>    <s:selectItems .../>
>    <s:selectItems .../>
> </s:selectItemGroup>
> and, as a shorthand to put each list in a distinct group
>    <s:selectItems group="Foo"/>
> I don't understand why this isn't in JSF core.
