Hi, Matt,
Take a look at the EOQualifier JavaDoc and search for "Using
Selectors in Qualifier Expressions".
I think you'll find your answer there.

I have an object with the code below. When I try this search from a
WOComponent - EOQualifier.qualifierWithQualifierFormat
("hasOpeningPlusZeroDays
= 'true'" ,null); I get the error below. I don't understand why I'm
getting this error. hasOpeningPlusZero days is clearly reachable.
Can anyone provide a better debug message? I really don't understand
why I'm getting this error.
thanks,
matt
