Re: Nested tags : trying to get recursion to work
What does yout struts config file look like? Sounds like that is where the problem is... Also, you can't just start with a nest tag (to my knowledge) you have to have it in a nested:form or nested:root, but I may be wrong. The docs are a bit thin and I can't even get the examples to work properly -- Sloan - Original Message - From: "Pratima Aiyagari" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, July 02, 2003 6:33 PM Subject: Nested tags : trying to get recursion to work > I am trying to get recursive inclusion to work with > the nested tags. > > Here is what I'm trying to do: I have a directory, > which might have a bunch of files or more directories > inside of it.

Nested tags : trying to get recursion to work
I am trying to get recursive inclusion to work with the nested tags. Here is what I'm trying to do: I have a directory, which might have a bunch of files or more directories inside of it. Just like any regular directory structure. And I need to display all the directories and the files inside each. In main.jsp: There is a bean in the request whose getter [getDirectory] method returns a directory. So, this should be fine. In recursiveDirectories.jsp readflag=[] The directory bean which is now passed to nested:root has a getReadFlag method. So this should work ? Or not .. :-/ I get a strange exception. It says "Cannot find bean in any scope" Please see end of this post for the exact exception. It says it can't find some bean, but no indication of what that might be .. Any help appreciated!
