Hey Mike,
I've had this error many times and, in my case, the problem seems to be
in the template the newer version of XCode uses when I first generate
the project. MenuHeader.java and PageWrapper.java (see the errors
about having a "classless component") are not actually added to the
Application build target even if XCode says they are.
My solution is quite easy:
1. Select both files (MenuHeader.java and PageWrapper.java), right
click and select Delete; in the requester, select "Delete Reference".
2. Add Existing Files: Select the same 2 files from your current
working directory and add them to your project without requesting a
copy to be made.
3. Rebuild and enjoy.
Hope that helps,
Jonny
Hi -
I've used D2W several times to test eomodels but not in a while (i.e.,
I've updated Java and OS X to 10.3.5 and Java 1.4.2 update 2) and now
it doesn't seem to work at all. I created a simple EOModel with a
table called name that has 3 fields, nameId, firstName and lastName.
I also tried this with 3 other eomodels that i have in production and
they all end up with the same errors.
When I run a newly created Direct To Web application project, as soon
as I click Login, I get this error message:
Error:
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: [
valueForKey()]: lookup of unknown key: 'visibleEntityNames'. This
WOComponent does not have an instance variable of the name
visibleEntityNames or _visibleEntityNames, nor a method of the name
visibleEntityNames, _visibleEntityNames, getVisibleEntityNames, or
_getVisibleEntityNames
In the Run log I have this;

I'm not sure where it's coming from but it seems like the frameworks
aren't finding the pages. I checked the .woa package and all the pages
and jars seem to be in there.
Any ideas? I spent a bit of time trying to debug this but want to make
sure it's not one of the updates that has broken something.
Thanks
Mike
