Hi All,
I have a User object with a to-many relationship to a Keyword
object. The Keyword object has an inverse to-one relationship back
to User.
Using Web Assistant, I've customized the New/Edit Keyword template
to use a D2WEditToOneRelationShip popup box that shows a list of
users. Whenever I save a new keyword, I get a
java.lang.IllegalArgumentException error.
From the stack trace, it looks like this is being caused by the
User.addToKeyword() method. I understand that this method expects
an object as an argument but D2W is passing the index of the select
box which is an int(userID).
This is my first foray into WO so i've pretty much done it all by
the book. All classes were generated by EOmodeler and have not been
modified yet.
I've also tried using D2WEditToOneFault and that yields the same
error.
What gives?
Error:
java.lang.IllegalArgumentException: Object value '5' for column 1
is not an instanceof String.
Reason:
Object value '5' for column 1 is not an instanceof String.
I tried what you described (I think) and it did not have the problem.
Given the error, I would suspect that the EOModel is at fault.
Look at the attributes in EOModeler. Does the "External Type" match
what you expect? Check the "Value Class (Java)" also. Note that
EOModeler will show you the "Value Class (Obj-C)" by default, for
historical reasons. This is not the same as "Value Class (Java)".
Make sure that the primary and foreign keys are not also class
attributes. They should not have the little diamond next to their name.
My version of the project is downloadable at http://www.ganymede.org/
wow/resources/20070116/Fijai.tgz. Does this example show you anything
different? I used a MySQL database.
If you find the error, let me know what it was.
thanx - ray
