Throw an error if component binding is used illegally
-----------------------------------------------------
Key: TRINIDAD-1733
URL: https://issues.apache.org/jira/browse/TRINIDAD-1733
Project: MyFaces Trinidad
Issue Type: New Feature
Components: Components
Affects Versions: 1.2.13-core
Reporter: Andrew Robinson
Assignee: Andrew Robinson
Because users illegally use component binding with non-request scopes, we
It would be very good to have a way to stop users from illegally using
component binding of Trinidad components.
<tr:outputText binding="#{requestScope.myBean.outputComponent}" />
vs.
<tr:outputText binding="#{sessionScope.myBean.outputComponent}" />
I suggest we put code into UIXComponentBase of Trinidad that when the parent
component is set on a component, we check the old view root and the new view
root and if they are not the same, throw an exception. This way we would
catch these design errors before they are filed as bugs in the components.
I have seen many people trying to flag these situations as bugs in the
framework instead of realizing it is a problem with their application.
