difficulties with cross-model relationship
All: I have an entity called Paper in a new model A that I would like to relate to an entity Employee in an established model B. Each of them are in their own framework project but both models use the same database. I was hoping to make this a many to many and flatten it. I've tried many things tonight to get this to work but apparently I'm doing all the wrong things. Apple's documentation seems to indicate that I should be able to resolve type references to any models included in the model group. I've added B eomodel to the model group section in my EOGenerate file. I've tried adding B.framework the build path of A.framework. This seems to do the right things and add the join table, etc., but then model B can't resolve type references to the entity in model A. I'm assuming I'm just really confused about how this should work but I've reached my limit for banging my head against it. I'd be really grateful if anyone doing something similar could share how they may have gotten this working. T ___ Do not post admin requests to the list. They will be ignored.

Ok... so we have three different versions of that string and
no clue what's going on because Eclipse keeps telling me that
the .java file is in UTF-8. But copy and paste into another
app (i.e. Mail) doesn't work.

if the Strings come from the database through EO String

Re: Downgrading WebObjects from 54 to 52
Hi Julien,
you can use WO 5.2 and 5.4 on the same Mac.
I copied all the WO 5.2 stuff under /Developer/WebObjects52 and
followed the the description under
http://wiki.objectstyle.org/confluence/display/WO/WO+5.4+Getting+Started#WO5.4GettingStarted-DevelopingwithbothWebObjects5.4and5.3
The changed properties files and scripts to switch between 5.2 and 5.4
are attached.

Hi Kieran, I am implementing a system that assigns a user to a role and then each role is given a specific set of navigation tabs for the pages that they can see. This is all easily done using the ERXNavigationMenu from ProjectWonder. I then customize a given page where necessary (for example read only v.s. editable) for a given role and point to it from that role's navigation menu. This works really well for a small number of roles. You just create as many variations of a given page as you need for the corresponding roles. For how I do it, Roles are used to aggregate privileges and specific privileges grant access to pages, menu items, etc. Man, you always give me new twists to think about! Yeah, I annoy lots of people like that! :-P But you're right, a role would have a hard time specifying privileges, it is much better to come at a Role as an aggregate of them. Would this mean that a person can have multiple roles in the application? That is certainly possible, it really depends on the business domain. Often I find that some users will have a single role and some will have multiple roles. Thing of McDonalds. People working the tills might have the Counter Staff role. People doing the cooking might have the Grill Man role. A Manager might then have the Counter Staff and Grill Man role in addition to their specific Manager role. If they can, can you somehow limit their role to the context that they're working in, in the application? For example, I run a (parabolic - if you know what I mean ;-) web application that publishes three webzines. On two of them I am a writer and on the other the publisher, can I be assigned to a different role depending on which webzine area I have navigated into? I think that you would have to have Magazine specific roles for that e.g. Publisher (Cooking for Techs), Writer (Marine Biology Monthly). You could have template roles that get copied and modified for each Magazine. Where this approach breaks down is when you start to have too many roles and/or you are customizing too many pages to correspond to the roles. I think at that point you'd want to create one page level component and set privileges at the field level (as read only or editable or invisible) depending on the privilege assigned to the role. As always, I think a lot depends on the complexity of your application. And I am not sure what the rule of thumb would be for moving from one way to the other. Do your access control strategies contemplate setting access right down to the attribute level on a page? It would not be fun otherwise, would it? Oh I'm having plenty of fun without digging this far down ;-) Where is Goat Island, again? http://www.niueisland.com/ In other news, the WebObjects Refuge Island has just been engulfed by a giant Tsunami coming from Tonga. It is not known how many survivors there are.

Re: Pound symbol Solved...
I'm still really a WO451 programmer, so what do I know, but doesn't Xplode allow you to set a default encoding for your text (source) files? One might expect String s = £; to cause the creation of a UTF8 string literal. Suppose your source code default encoding was ISO 8859-1 ... what byte sequence would javac emit? If on the other hand Xplode's default encoding for text files was UTF8, this problem shouldn't crop up -- unless you introduce it with eg an external component editor.

AjaxTabbedPanelTab
Hi, Is there a good way to prevent switching from one tab to another if there are pending edits in the editing context? I'm thinking of handling this when the tab tries to set the property bound to the isSelected binding. And then set a message in the request's user info object which gets displayed when the tab's pane is displayed. ___ Do not post admin requests to the list. They will be ignored.

Re: AjaxTabbedPanelTab
I guess another alternative would be to have each component displayed under each tab to use its own editing context. Then just let the user switch tabs at will. Hmm...

Also, I wanted a new model (same database) for this faculty project because it doesn't need to know about timesheet stuff. So, I built that model (what I was calling 'A') and I was trying to build a relationship to the Employee data in 'B'. Since the many to many requires the Employee entity to maintain pointers back, it isn't working. But the truth is, for this project I'm only interested in faculty - something Employee doesn't even know about. can of worms. I think I have a problem with approach. I think the best approach may be to sub-class my user types in a third framework? I've been putting this off. :-) I am really not sure what you are doing and what you are seeing so it is hard to advise you on the best direction to take. I understand why the approach I was taking won't work. So, maybe you can vet the one I'm trying today. I was thinking I need to create a framework to relate LDAPPerson and Employee in a single framework and create new model there with GenericUser. This GenericUser would then wrap both their ldap source and their employee data source in a single entity and hold that relationship. It sounds like a lot of overhead but maybe the right thing to do. Then I could subclass that user into FacultyPerson, StaffPerson, StudentPerson, etc. , maybe even in separate frameworks. This sounds like it could put me in a better position to achieve what I want. I think that is exactly the right thing to do: create an object to wrap and hide the complexity of the ldap source and the employee data source. Chuck Thanks Chuck. I've made some progress on this today. One place I'm apparently getting stuck is putting valid qualifiers in my model for my inheritance structure. I've got a new abstract entity LDAPEmployee which inherits from InetOrgPerson (from my ldap schema). I added a relationship employee between this entity and my Employee entity in my employee source using the the common employeeNumber. So far so good. However, I want to put a qualifier on LDAPEmployee that requires an Employee entity to exist. My hope is to be able to ask for LDAPEmployee objects and only get ldapusers where there's also a related Employee. EOF does not support that. So, I created a restricting qualifier in Entity Modeler that looks like: employee!=null That qualifier can only refer to attributes of the object (cols in the table). I get an error that there's a failure to parse my qualifier. Is this because the syntax is bad or because I can't create a qualifier like this? I've looked everywhere for definitive information about what is valid for these qualifiers and there's very little info out there. Can't do it like that. You could add a method employees() to LDAPEmployee that did a qualified fetch perhaps.

See, the problem is that the person who has been doing most of the work on those projects lately is also the person who wrote most of those blogs. Rumours has it that he also has a job. :-) are you saying this person actually has to do a real job for a living ? That is criminal. His employers should just pay him for making all of our lives a million times easier than they would be without him churning out all of this goodness.
