inputParam component
--------------------
Key: MYFACES-192
URL: http://issues.apache.org/jira/browse/MYFACES-192
Project: MyFaces
Type: New Feature
Versions: 1.0.9 beta
Environment: All
Reporter: Rob Decker
Attachments: inputParam.tar.gz
inputParam extends inputHidden by adding an attribute, paramValue, which allows
value binding predefined form values to a managed bean. For example, if you
have a managed bean named searchBean with a setLastModified(Date d) method you
can create a hidden form element with a preset date:
<h:form>
<h:commandLink action="searchBean.search">
<x:inputParam value="#{searchBean.lastModified}" paramValue="04/05/2005">
<f:convertDateTime type="date" dateStyle="short"/>
</x:inputParam>
</h:commandLink>
</h:form>
renders:
<input type="hidden" value="04/05/2005"/>
When the form is submitted searchBean.setLastModified is called with the Date
object. When the link is clicked there is no need to look in the request for
the parameters of the search. There is no need to modify the bean if a
different search is required. Just create a new form/commandLink and specify
the new parameters. I used it to create quick searches: New in last
Day/Week/Month using the same bean for a full fledged form that let's the user
specify the dates without having to modify the bean or tie it to faces/request
to populate it.
The attached archive contains the component package and the required xml
fragments for the tld and faces-config.
