I just downloaded and installed the brand new Entity Framework 5.0 beta 2 which was released yesterday. Now, in my EDMX model file, it doesn't matter wether or not I set "Lazy loading enabled" to true or false.
I still need to "Include" the association properties that I want to use for the retrieved objects.
Can anyone explain why?
I ended up fixing this issue by (sadly) making a class which inherits my ModelContainer. In this class' constructor, I set the settings to enable lazy loading - even though it was already set in my EDMX file itself.
This worked just fine. Strange issue indeed.

I dropped in an external jar file using the new jar design element of Notes 9.
I tried referencing it from a managed bean, and was able to compile. In runtime, I get a NoClassDefFoundError when I try to use the methods in the jar.
I have refreshed, cleaned, and rebuilded. Version 9 server and designer.
I remember in the past with 8.5.3 there was lots of issues getting the build path correct, but I thought that the new jar design element was supposed to take care of the issues. Most of the research I have found is from the days of 8.5.3 and earlier.
Any advice would be appreciated. (I am purposely not tagging java on this question since I think only XPagers would understand what to advise here)
2 steps to fix a potential issue:
Remove the database from designer. Delete the workspace project (only the project not the entire workspace!)
Add the database back. Check in the Java build path (right click in the navigator view on the database) that the Jar directory is included
Sometimes step 2 alone does the job, so start with that first.
As I remember early R9 versions have had issues with Java/JAR design elements. Put your JARs into WEB-INF folder (Project Browser view), that is my preferred way to use them.
Are JAR files in WebContent/WEB-INF/lib available to Java design elements in Domino Designer?
The solution that Stephan posted worked for my first attempt yesterday, so I am leaving it as the accepted answer. Today, I had to change the package name and the issue cropped up again.
This time nothing that Stephan or Frantisek suggested work to fix the NoClassDefFoundError exception. After trying everything, I came across this blog post. (A big thanks to Panu Haaramo who posted it in the comments in the answer of the SO that Frantisek's links to)

Renaming the jar caused the runtime engine to find the class file properly. Try this as well, as the solutions above to fix this problem. It is certainly an easy fix.
I'm getting 110 warnings in my build after installing Azure SDK 2.3 that I don't recall seeing before. They are all for the file "Microsoft.WindowsAzure.targets".
An example of one such warning is:
The element 'PropertyGroup' in namespace 'http://schemas.microsoft.com/developer/msbuild/2003' has invalid child element 'CloudToolsVersion'.
Has anyone else encountered this problem or know the right way to fix it?
Well, it looks like I just needed to close any open editors for msbuild project files to get those to disappear. Other answers I found suggested on the web were to disable schema validation or to extend the schema myself.
Very scary! From your solution and hints from other similar questions, I think I know what's going on: When any build script file (such as a .props) is open in a text editor, it turns on /validate. This is used to see red wavies in the editor and gives the warnings when the project is loaded by any MSBuild task. The schema holds the various element used by the MS targets infrastructure, and doesn't know anything else. I'm not sure what good that is, but there you have it.
I am working through the pluralsight videos on MonoTouch. At one point, the trainer right clicks on the name of a derived class, and in the 'refactor' menu there is a function to override/implement members of that class. When I click however (latest version), I see only 'rename.'
The person in this link had the same issue some time ago and has included screenshots - but noone replied to them in the MonoTouch discussion group:
http://monotouch.2284126.n4.nabble.com/Right-Click-Class-name-gt-Refactor-gt-Override-Implement-members-tt4655504.html#none
Has anyone experienced (and resolved!) this?
Some of the refactoring features were reorganized or removed (for now) in the rewrite of the code code completion engine that took place for MD 3.0.
You can still access this particular feature two ways:
1) After typing the "override" keyword, MD offers the members you can override/implement. Selecting one will cause it to be stubbed out.
2) You can override many members at once using the "Edit->Show Code Generation Window" command in the class body. This command doesn't have a keybinding on Mac by default, but you can assign one in Preferences.
MonoDevelop 3.0 (and later) removed some features (including a few about refactoring) since they were not as stable, fully functional (complete) or buggy.
The same features (or similar ones) are likely to come back in future releases.
EDIT: might be fixed in latest Xcode 4.0.2 (just released) - I'm downloading this out now, and will re-edit once I've tested it.
Create two entities (call them "Manager" and "Employee", to stick with Apple's docs).
Create a relationship, "worksFor" from Manager (1) to Employee (many), and mark it as "not optional". (you'll probably need to create 2 relationships, mark 1 as inverse of other)
Hook up an interface using IB, according to Apple's original docs (NB: these don't work any more, but here's an almost exact recreation of the basic setup in Xcode4: http://rgprojection.blogspot.com/2011/04/xcode-4-and-core-data-macos-x.html) and use Bindings (as described in the linked post) to create/add/delete the objects.
Now try to save. ERROR: "worksFor is a required property".
In previous versions of Xcode, this worked as expected: you'd told Xcode that there was a bidirectional relationship, you told it that it was required, and so when it added the "Employee" to the "Manager", it automatically hooked-up the inverse.
Has anyone else worked out how to make Xcode4 do what it's supposed to? Is it an Xcode4 bug? I know that some of the CoreData support in Xcode4 has been deleted, with no replacement (yet), so I'm wondering if this has been deleted too?!
EDIT: here's another project, one I made from scratch, same problem. Although (xcode4 bug, definitely!) this time I created the Relationship in the "grid" editor view rather than the "tree graphical" view... and the generated source code for objects was different (should not be the case, obviously)

EDIT2: StackOverflow was showing the screenshot above, but has now removed it, you'll have to click on the link. Sorry.
I haven't seen the problem you describe and I've created several data models under Xcode4. It appears to work just like it did in previous versions in that regard. I think you've got something else going on.
Xcode 4.0.2 seems to have fixed the problem - everything works as expected now, with no changes to code :)
Is it possible to mix them? I'm asking because I have a big project that uses Subsonic 2.x generated classes (in a compiled dll) but would like to start using 3.x for new stuff.
I tried it last night with a project where I had references to both subsonic.dll and subsonic.core.dll but that didn't work with ambiguous references, etc. So removed 2.x and then got an issue with my older compiled subsonic generated classes in that they needed Subsonic 2.1 to run.
Hmm... I think there's a small chance that you might be able to do this, but you'd need to use the full qualifying class names (namespace.class) for a lot of code because there might be naming conflicts. It wouldn't be easy to do and definitely not recommended. (It might not can even be done.)
You can't move from 2.x to 3.x without doing a lot of recoding. I have a bunch of big projects in 2.2 and after trying to update to 3.0, I ran into some issues so I've decided to keep them in 2.2. I'd love to upgrade to 3.0 and use the new stuff, too, but I don't have the time (right now) to recode the stuff that changed between 2.x and 3.0.
I do recommend updating to 2.2. There shouldn't be any backwards compatibility issues between 2.1 and 2.2. I was able to update to 2.2 by just changing out my reference.
Just curious, are you using ActiveRecord or Repo implementation?
You only have 2 options:
stay in 2.1/2.2
update your code to 3.0
Thought I'd follow up here and let people know that I was able to get this to work. What i chose to do was to edit the Subsonic 2 source code and put it into a Subsonic2 namespace (everything), recompile to subsonic2.dll, etc. Had to modify the web.config slightly, then went and modified my old code to reference subsonic2, etc.
Am now able to mix both Subsonic 2 and 3 in the same project.

Jim--I'm using ActiveRecord. The 2.x is in one namespace and 3.x would be in another. However, I guess the question is whether the 2.x can be compiled to run with the 3.x runtime.
Thanks,
Gerry
