Hmmm... I tried changing the column type in openbase to an integer and
saved the change. Then I deleted my EOAttribute from my entity and
added it back, this time using intBoolean. But as soon as I fetch my
EO from the database it blows up with the following exception:
er.transaction.adaptor.Exceptions - Database Exception occured:
com.webobjects.foundation.NSForwardException
[java.lang.NoSuchMethodException] Class java.lang.Number does not
implement method valueOf:java.lang.NoSuchMethodException: Class
java.lang.Number does not implement method valueOf
The query looks right though. It just seems that the EOAttribute is
having trouble converting the value from the database to the type used
in the EO.

Hi Mike,
Not sure I understood what you mean by flag. :-)
Anyways, here's the boolean protototype from ERPrototypes as defined
in EOJDBCOpenBasePrototypes.plist:
{
adaptorValueConversionMethodName = toString;
columnName = "";
externalType = varchar;
factoryMethodArgumentType =
EOFactoryMethodArgumentIsNSString;
name = boolean;
valueClassName = "java.lang.Boolean";
valueFactoryMethodName = valueOf;
valueType = S;
width = 5;
},
and the intBoolean prototype is setup as follows:
{
adaptorValueConversionMethodName = toString;
columnName = "";
externalType = bool;
factoryMethodArgumentType =
EOFactoryMethodArgumentIsNSString;
name = intBoolean;
valueClassName = NSNumber;
valueFactoryMethodName = valueOf;
valueType = c;
},
I tried both and neither one works for me. Anybody out there using
OpenBase 10.0.11 with and boolean properties in your columns and EOs?
I've been trying all kinds of things to get these booleans to
work... And I just thought of one which might work. I'll change
the type in openbase for those columns back to integer type. Then
I'll use the intBoolean prototype from ERPrototypes. I assume
that's what the intBoolean prototype is for: to have a boolean in
your EO stored as an integer in the database. Right?

"boolean" in erp = varchar, not boolean, "intBoolean" in erp =
number, "flag" = probably what OB is calling "boolean", but you'd
have to check if the OB variant of erp declares this properly.

Hi All,
There seems to be something wrong with booleans when using
OpenBase and ERPrototypes.
In OpenBaseManager the column type for my column says boolean:
<Picture 2.png>
In openisql (command line) I can query like this:
select count(*) from cliente where suspendido = true
of like this:
select count(*) from cliente where suspendido = 1
In entity modeler, if I configure my attribute using the boolean
prototype from ERPrototypes as shown below, then the queries don't
return the right number of rows. The update statements generated
by EOF don't work either (even though they look right).
If I model my attribute as an integer then the queries work okay
and the update statements issued by EOF work too. By I don't like
having an Integer in my accessor methods in my EO for a boolean
column. I want to use boolean.
Looking at the screenshot below, does this look like the boolean
prototype is setting the fields correctly for a boolean column in
OpenBase? Anybody wants to guess? Anybody using booleans in
OpenBase and ERPrototypes?
