strict attribute
----------------
Key: MYFACES-307
URL: http://issues.apache.org/jira/browse/MYFACES-307
Project: MyFaces
Type: New Feature
Reporter: Martin Zdila
Priority: Minor
Hello
It would be fine to implement strict attribute to JSF components. If this
attribute was true and binding in value attribute was invalid, then component
wouldn't be rendered. It is useful if someone use one JSF page whith
components bounded to backing bean where the bean is not allways of the same
class.
For example I have some page.jsp using backing bean BeanCaseA that extends
BeanCaseGeneric or BeanCaseB that extends BeanCaseGeneric. The bean is
accessible through beanHolder.beanCase. Then:
#{beanHolder.beanCase.propertyX} - exists in BeanCaseGeneric (so in BeanCaseA
and BeanCaseB too)
#{beanHolder.beanCase.propertyA} - only exists in BeanCaseA
#{beanHolder.beanCase.propertyB} - only exists in BeanCaseB
The syntax would be eg:
<h:outputText value="#{beanHolder.beanCase.propertyX}" strict="false" />
If strict parameter is't specified then the default value would be true.
