-------------------------------
Summary: Improve CDK c:forEach typing
Key: RF-12296
URL: https://issues.jboss.org/browse/RF-12296
Project: RichFaces
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: cdk
Affects Versions: 4.2.2.Final
Environment: All
Reporter: Paul Dijou
As we can see on [this
comment|https://issues.jboss.org/browse/RF-10037?focusedCommentId=12696717&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12696717],
you currently need to assign a list/array to a var before using it inside a
{{<c:forEach>}} or the CDK doesn't know its correct type.
As suggested by Lukas, I agree to add a {{cdk:itemType}} (or {{cdk:type}} like
in the {{<cdk:object>}} tag) to specify manually the type of the object inside
the iteration. If this attribute is present in the {{<c:forEach>}}, then the
CDK use it to cast the object, otherwise it does the same as currently, no
regression.
In addition, for Enum, I would also try to use the initial import :
{code:xml}
<cdk:import package="org.richfaces.component" names="MyEnum" />
{code}
In order to know the type of each Enum and then be able to correctly cast the
following code :
{code:xml}
<cc:implementation>
<c:forEach items="#{MyEnum.values()}" var="item">
#{item}
</c:forEach>
</cc:implementation>
{code}
