Yep this is because UserDetail has it's own primary key and the primary 
key of the refering User. Your asking for the UserDetail object with the 
primary key of the User which doesn't exist.

You get this because the database layer is trying to case a User object 
found by its primary key into a UserDetail object.

Yep. UserDetail.findUserDetail("user_id = ?"); Or make a 
findUserDetailByUser which does the SQL behind the scenes. You may also 
want to make user_id an indexkey if performance becomes a problem.

[Bodington-developers] quick question on finding things

[Alistair Y. <ali...@sm...>]

Before I dive off into bodguts, has anyone seen this before, or any  
suggestions as to why it happens?

UserDetail bodUserDetail = UserDetail.findUserDetail 
(user.getPrimaryKey())

where user = org.bodington.server.realm.User

always gives a ClassCastException. Is a User.PrimaryKey different  
from a UserDetail.PrimaryKey?

Always have to use sql to get UserDetail from a User.

Yeah.  Ideas for alternatives are welcome, but I think it'd be helpful
to centralise the work of noteEdit().  The BuildingSession interface
already publishes that method, and I think most tools should be able to

[Bodington-developers] ResourceSummary

[Matthew B. <mat...@ou...>]

We have a class org.bodington.server.resources.ResourceSummary that 
seems to be returned by a couple of routines in NavigationSession:

	public ResourceSummary getRootSummary()
		throws BuildingServerException;
		
	public Vector childSummaries( PrimaryKey resource_id )
		throws BuildingServerException;

but it seems like these methods never get called. What was the idea with 
ResourceSummary and is it going to be developed further?

I see you're only recording updates for "properly" written bodington 
tools that do their work though sessions (assessment tools ;-). What are 
you recording the dates for? Managers or users?

Currently working along this route and now I have a NavigationSession 
that doesn't know the current resource. I have split NavigationSession 
from the BuildingSession Hierarchy although I may join them up again later.

I am also looking at removing the RMI stuff from the code as it isn't 
used anywhere.

I have also split UploadedFiles into UploadedFileSession that can be 
obtained from a BuildingSession.

All this is on WebLearn (spring branch) at the moment but may well start 
filtering across to Bodington unless people have objections.

[Bodington-developers] New IMS CP and Leeds developments on HEAD

[Peter C. <Pet...@me...>]

New for your delectation and delight:

- Improved content package export and modification.  Correct namespace
used for the 'lang' attribute; namespaces accepted for the 'lang'
attribute; modification of the basic properties now correctly updates
the metadata and tidies up any previous screw-ups.  UHI, you'll want to
grab this I think - XMLRepository and a big chunk of the
BuildingSessionImpl changes are related to this.

- Creation and edit dates and usernames are stored on resources.
They're not displayed yet.  Expect an email from Leeds shortly opening
up a discussion on where they could be displayed.  Logic for updating
the last edit date and user is centralised in
BuildingSessionImpl::noteEdit().

- Deadlines are now expressed as a date and time rather than just as a
date.  Parsing and rendering of deadlines is centralised in Facility
(sorry!) - parseDateInput and outputDateInput are the methods to look
at.  Creation templates have been modified to render using these new
methods, so an alternative mechanism such as the Weblearn JS calendar
(or going back to one input box) could be implemented simply by changing
these two methods.

- When displaying MCQ results, the display can now be ordered by the

I don't think so. A user only has one NavigationSession and it is 
designed to track where the user currently is in the site. The 
NavigationSession is store in the HttpSession so that a new 
NavigationSession isn't created for every request. The 
SessionInitializer gets it from the HttpSession and hands it back to the 
Request.

This works for 99% of the time but not all the time because a user may 
be in 2 parts of the site at the same time. If someone has uploaded a 
file called test.html into a resource called myfiles (URL: 
/myfiles/test.html) and the test.html contains links so other content:

<html>
<head>
<title>Hello</title>
<link href="../bs_virtual_auto.css" type="text/css" rel="stylesheet">
</head>
<body>
Hello <img src="/otherplace/myimage.png"/>
</body>
</html>

Now after loading the /myfiles/test.html file the browser will request 
the contained resources:

/bs_virtual_auto.css
/otherplace/myimage.png

but these are contained in different resources and so when the requests 
come in the NavigationSession will the switched to the resource 
containing the file (root resource and /otherplace) now depending on how 
  these requests get processed it maybe that the following happens:

- /bs_vistual_auto.css sets NavigationSession resource to /
- /otherplace/myimage.png sets NavigationSession resource to /otherplace
- /bs_virtual_auto.css starts to output the stylesheet using 
NavigationSession to discover the resource properties but these are now 
comming from /otherplace.
- /otherplace/myimage.png request completes
- /bs_virtual_auto.css request completes.

Storing the current resource in the HttpSession is silly due to 
concurrent requests. So what should we do?

NavigationSession doesn't contain the idea of the current resource any 
longer?
I don't think it is sensible todo locking around this due to the fact 
that the NavigationSession could be accessed at any point during the 
request and it would create problems if we ever wanted to cluster Bodington.

Anyone have any comments?

This is how most other websites work. If I order something from Amazon

It seems that lots of bits of code call this method asking for a

Well, here we have two models.  Both assume your comments about users.

First model:
- User makes changes to some fields.
- User saves changes; no changes are saved due to an error with a date.
- User ignores error message and walks away thinking 'job done'.

Second model:
- User makes changes to some fields.
- User saves changes; as many changes as possible are saved due to an
error with a date.
- User ignores warning message and walks away thinking 'job done'.

Which do we prefer?

I prefer the MCQ model.

If the date field contains anything and it can't be parsed into a date 
shouldn't it warn the user and fail to save the form? Users are rather 
good at not reading error messages correctly or at all.

If the field is empty (or set to "none"?) then we just ignore the date.

[Bodington-developers] RFC: minor change to MCQ deadline parsing

[Peter C. <Pet...@me...>]

Most resources with deadlines accept invalid dates when a user modifies
the resource.  They blank the date and alert the user.  This seems to be
acceptable behaviour.

MCQ deadlines behave differently - if the deadline contains an invalid
date, no changes are saved and the user is prompted to press Back and
review the form.

I'd like to change the behaviour of the MCQ deadline to match the other
dates.  Any objections?

[Bodington-developers] for the agenda

[Alistair Y. <ali...@sm...>]

Sorry I can't make it, especially the Tetra day. However, is this  
working looking at?

JISC
Sept 2006 call
Next generation environments for learning, teaching and research.  
Build and develop tools and integration platforms
Develop web-service enabled tools

is this the exploration route from bod to Tetra? The portal stuff I  
did was experimental but if a bod tool was a web service... would let  
us port a couple of bod tools to ws and a prototype "bus" to co-ord  
them.
