[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2707) Avoid proxies in directory display
[ http://jira.jboss.com/jira/browse/JBSEAM-2707?page=all ]
Christian Bauer closed JBSEAM-2707.
-----------------------------------
Fix Version/s: 2.1.0.GA
Resolution: Done
Found the proxy:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "DEFAULT_FILE_ID", nullable = true, unique = true)
@org.hibernate.annotations.LazyToOne(org.hibernate.annotations.LazyToOneOption.NO_PROXY)
private WikiFile defaultFile;
This is in the WikiDirectory subclass of WikiNode. Hibernate seems to ignore the NO_PROXY
and bytecode enhancement when you query "from WikiNode" and attaches a proxy
instance for this association. Switched to eager fetching.
Avoid proxies in directory display
----------------------------------
Key: JBSEAM-2707
URL: http://jira.jboss.com/jira/browse/JBSEAM-2707
Project: JBoss Seam
Issue Type: Bug
Components: Wiki
Reporter: Christian Bauer
Assigned To: Christian Bauer
Fix For: 2.1.0.GA
Sometimes a Hibernate proxied instance sneaks into the list of items in the Wiki
directory display. That leads to CCE because we don't handle WikiFile, only its
subclasses in some generic handlers:
javax.servlet.ServletException: /includes/directoryBrowserIconMenu.xhtml @10,113
onmouseout="jQuery(this).children('.dirItemIcon').attr('src','#{icon}').toggleClass('mouseOver')":
/dirDisplay_d.xhtml @207,122
value="#{themePath}/img/#{wikiDocumentIconHandler.getIconName(node)}":
java.lang.ClassCastException: org.jboss.seam.wiki.core.model.WikiFile_$$_javassist_64
Need to find out why there is a proxy there, this is supposed to be a direct database
query in a fresh persistence context.
