Are you using Wonder? Prototypes?

Hi George,

Have you tried generating with any other templates and gotten similar results? If no...

http://wiki.objectstyle.org/confluence/display/WOL/EOGenerator+Templates+and+Additions

If you're having trouble with other templates, check your EOModel and make sure the value type is 'c' on that attribute's prototype. That 'c' tells WebObjects it's a boolean being represented by a number. But only on numbers! Oddly, the 'c' means something else for strings :) In fact, check your model first. That would be my guess. I'm using Eclipse 3.4 and I don't remember if the interface is identical in 3.3, but it should look something like:

or perhaps

Environment:
Windows Vista, Eclipse 3.3, Wolips plugin 3.3.5xx,
EOGenerator v1.7 (configured as a builder in eclipse), MySQL 5.0.51a

Issue
We are setting up a new development environment for a developer and are experiencing an EO Generation issue. All our development component versions come from a standard copy in our repository.


In our entity layer, Boolean entity attributes are mapped to java Boolean objects and MySQL tinyint(1) by a prototype called ‘flag’. On all development environment the EOGenerator maps this correctly, except for the new environment. We have pain-stakenly confirmed all the development components are identical (eogenerator, templates, wolips-plugins, eclipse, mysql, mysql drivers, and jdk versions) and the project properties (build paths etc), external properties files (<user>wobuild.properties).

Example
What we see after a clean (and the eogenerator builder executes)
    public Boolean isAutoGenerated() {
        return (Boolean)storedValueForKey("isAutoGenerated");
    }

    public void setIsAutoGenerated(Boolean aValue) {
        takeStoredValueForKey(aValue, "isAutoGenerated");
    }

What new developer see after a clean (and the eogenerator builder executes)
public Number isAutoGenerated() {
return (Number)storedValueForKey("isAutoGenerated");
}


    public void setIsAutoGenerated(Number aValue) {
        takeStoredValueForKey(aValue, "isAutoGenerated");
    }

Question
Does anyone have a resolution for this (i.e. what causes it and how to resolve it)?


Many Thanks
