[jira] Commented: (WICKET-3197) getMarkupId() can be used only if the component's markup is attached

["Juergen Donnerstag (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-3197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12964332#action_12964332 ] 

Juergen Donnerstag commented on WICKET-3197:
--------------------------------------------

The problem actually is that the component already is detached when addOrReplace() copies the markup ID to the new component. Copying / retrieving means we first try to read the markup to find the id. Since it's already detached the error occurs. IMO the right solution is a hidden copy method Component.setMarkupId(Component)
