[jira] [Commented] (WICKET-4545) MarkupNotFoundException for Fragment and TransparentWebMarkupContainer

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-4545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271481#comment-13271481 ] 

Martin Grigorov commented on WICKET-4545:
-----------------------------------------

The problem is in org.apache.wicket.markup.Markup#find(String) method which skips the body of the ComponentTag assigned to TransparentWebMarkupContainer.
#find() method looks for the child's markup only at one level depth but it should look one more lever deeper for TWMC. But since Component#onComponentTag() works with a copy of the real ComponentTag I see no way how to mark the ComponentTag as auto or to set it some other flag/userData which to be used when deciding whether to skip the children or not.

Anyone have ideas ?
