I received one suggestion to define a serializable class to contain
the array and then serialize the array objects to the NSData/BLOB
type, instead of ERXMutableArray. I may give that a try. Is that a
viable approach? Any examples out there of doing this?
Thanks,
Jeff

Hi,
I had a similar problem with MySQL (mysql-connector-java-5.0.4-bin.jar
is the latest one I've tried) and mutableDictionary. There were two
solutions that worked for me:
1. Change externalType to TEXT in model while leaving BLOB in the
database (i.e. generate sql with TEXT and change type to BLOB after
that).
2. Modify generator templates to have something like:
public er.extensions.ERXMutableDictionary uploadsFileNames() {
try {
return (er.extensions.ERXMutableDictionary)
storedValueForKey("uploadsFileNames");
} catch (ClassCastException e) {
return (ERXMutableDictionary)
ERXMutableDictionary.fromBlob((NSData)
storedValueForKey("uploadsFileNames"));
}
}
Both solutions are really dirty and can lead to unwanted side effects,
so I've decided that it really doesn't worth the effort and refactored
my model not to use these prototypes at all.

Hello,
I've taken Dave's SooperSeekrit Screencast project as a starting
point to
start playing with EO objects using the Wonder Framework.
Using Entity Modeler (with Frontbase prototypes), I've added an
ERXMutableArray to one of my classes that I want to use as an array
of
Boolean's in my code. In this case, what do I need to put as the
Value
Type? Also, for the width, will it be 4 bytes X the max number of
Booleans
to be stored?
I have tried just leaving these fields blank.
Then using the following code, I'm able to create a User object ok,
and it
shows up in my database with the Boolean array as a Blob:
Group group = Group.fetchRequiredGroup(ec, "name", "user");
Boolean [] bools = {true, false, true};
ERXMutableArray boolArray = new ERXMutableArray(bools);
User.createUser(ec, boolArray, first, last, password, newuser,
group);
ec.saveChanges();
However, when I try to a fetch from the DirectAction class as
follows:
EOQualifier qual =
User.USERNAME.eq(username).and(User.PASSWORD.eq(password));
User user = User.fetchRequiredUser(ERXEC.newEditingContext(), qual);
I get the following exception on the User.fetchRequiredUser line:
Apr 16 22:31:32 SooperSeekrit[49595]
(ERXDatabaseContextDelegate.java:105)
INFO er.transaction.adaptor.Exceptions - Database Exception
occured:
java.lang.ClassCastException: er.extensions.ERXMutableArray
I'm guessing it has to do with the missing fields?
Thanks,
Jeff
