Subject [jira] [Updated] (TAP5-1860) Access to protected component fields does not always reflect in subclasses
Date Thu, 12 Apr 2012 20:45:21 GMT

     [ https://issues.apache.org/jira/browse/TAP5-1860?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Howard M. Lewis Ship updated TAP5-1860:
---------------------------------------

    Summary: Access to protected component fields does not always reflect in subclasses  (was:
problems with protected component fields)

I've taken the code and renamed the classes slightly (to Grandparent and Parent), and enabled
component transformation logging.

> There seems to be a problem with the new feature introduced in 5.3.2 - https://issues.apache.org/jira/browse/TAP5-1801
> When I create a protected field in by base page class, setting the field in a subclass'
