[JBossCache] - Re: NPE when using optimistic locking with JbossCache 1.4.0.

It was not a problem that was fixed, just that there was unnecessary matching in some read-only cases where no validation was necessary. This was fixed in 1.4.1.CR1, but if your threads are writing to the node, then this is correct behaviour. In general, as a concept, if you have a lot of threads concurrently writing to the same data, optimistic locking will throw such exceptions.

[JBoss Portal] - Re: portlet drag and drop for different pages and users?

by thomas.heute＠jboss.com

This is not possible at the moment. We could probably have it, if it becomes a popular feature request and if time permits it or someone contributes to it :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999841#3999841 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3999841

[EJB 3.0] - Failed to lazily initialize a collection of role

by dmitryak

Hi... I don't speak English very well, so I apologise for that. I have a problem. I have made Entity Bean with collection field: | @Entity | public class DocumentEntity implements Serializable { | | private static final long serialVersionUID = 4842258583854141368L; | | private int id; | | private List<DocCategoryEntity> docCategories; | | @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER) | public List<DocCategoryEntity> getDocCategories() { | return docCategories; | } | | public void setDocCategories(List<DocCategoryEntity> categories) { | this.docCategories = categories; | } | ... | } | I deployed it on JBoss 4.0.4GA + EJB 3.0 RC8 FD. After that I made a junit which read a list of DocumentEntity-s (of course, I coded and deployd session bean which provide requered operations). And my problem is: when I try to read docCategories field of any item of result list I get an exception "org.hibernate.LazyInitializationException" But as you can see in my entity class source I am not using lazy loading (FetchType.EAGER). What did I make wrong??? Help, PLEASE!!!

[JBoss Seam] - Re: Injection and disinjection control

by igorla

Is it possible to config injection in such way that injection will be done only on instance create? Consider the following code: class A{ @In B b; C c; public getC(){..} } class C{ A a; public getName(){ a.getB().getName(); } } in .xhtml file present the following reference: #{a.c.name} What happens: C.getName is called - A instance doesn't have anymore reference to B due to disinjection after call A.getC() -> NPE is thrown. The code above is simplified and making C as component is not desirable. Probably this code is too much coupled, but it doesn't break any Java rules.

by asmo

Try : processInstance.getRootToken().setNode(node); As parameter you have to use the target node (Node object, not name..)

[JBoss Portal] - Re: Can't use myfaces tomahawk inputSuggestedAjax control in

by thomas.heute＠jboss.com

anonymous wrote : Is there anything which could prevent stuff working properly in a simple webapp to work identically in a portlet ? Yes, too many Tomahawk components cast the Request to an HttpServletRequest instead of working with the abstract ExternalRequest. It leads to a class cast exception when used in a portlet environment View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999830#3999830 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3999830
