• JPA CascadeType.ALL does not delete orphans.

  - by Paul Whelan

  I am having trouble deleting orphan nodes using JPA with the following mapping @OneToMany (cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "owner") private List<Bikes> bikes; I am having the issue of the orphaned roles hanging around the database. I can use the @org.hibernate.annotations.Cascade Hibernate specific tag but obviously I don't want to tie my solution into a hibernate implementation. Any pointers greatly appreciated.

• Unfamiliar Javascript Syntax

  - by user1051643

  Long and short of the story is, whilst reading John Resig's blog (specifically http://ejohn.org/blog/javascript-trie-performance-analysis/) I came across a line which makes absolutely no sense to me whatsoever. Essentially it boils down to object = object[key] = something; (this can be found in the first code block of the article I've linked.) This has proven rather difficult to google, so if anyone can offer some insight / a good online resource for me to learn for myself, I'd much appreciate it.

• Facebook like button showing in Firefox but not showing in IE

  - by CubanX

  Hello all, I have a Facebook like button on my page using the XBFML tag. I think the code is working, because it works in Firefox without a problem. But in IE 8 (running in IE 7 compliant mode), the button does not show at all. If I switch it all to the iFrame version of the like button it all works. But when I go with the XBFML tag it does not work. Anyone run into anything like this?

• Sharing DefaultHttpClient in Android. To synchronize or not to synchronize?

  - by johnrock

  In an Android app, I am using one static instance of org.apache.http.impl.client.DefaultHttpClient and sharing that instance in all activities and services of the app, so that this client may be used to log in once to a remote server and all subsequent user requests to that remote server will remain authenticated. Every activity or Service that makes a GET or POST to this remote server calls the same method : MyUtilityClass.gettHttpClient() Do I need to worry about synchronization of this httpclient? If so, what is the best way to handle this?

  I have got a simple question, but the answer is hard to find.

So, if (SPContext.Current.FormContext.FormMode == SPControlMode.Display) : show some extra links near the items in the xslt. How can I achieve this? I have already overridden the default ContentByQueryWebPart, is that the way? Thanks in advance.
