Adding a constraint throw excpetion

[hugoterelle]

Hi everybody,

I'm new in grails and when I try to create a new domain model, I have exception ...

I created a new grails application (called 'shopbazar') with a new domain model:

package shopbazar

class ArticleCategorie {   
    String Label
    double TVA  

   
    @Override
    String toString() {
        "${Label} (${TVA}%)"
    }
}

And everything works fine until I add the following code in my class,

    static constraints = {
        Label(blank: false)
    }

or any other constraint, on any field (I tried to add some other fields with others constraints)

The springtoolsuite tries to compile, but I receive the following errors:

I run with windows 7 64 bits, JDK 6 64 bits (I tried also with JDK 7 64 bits, it's the same result)

Thank you for your help

I would guess a naming convention problem by the exception message:
"java.lang.IllegalStateException: Failed to get field class
java.lang.String.Label"

Try something like:

String label

With a smallcaps "L"

Error messages are not always clear.  From what I see there is unhappiness with your BootStrap.groovy.  Did you try to use any classes in BootStrap.groovy that you didn't import first?

[ju8ular]

Agree with Alexandre on this one. But if that doesn't work, try prefixing your Label references with "this.Label"

Hi all,

I didn't touch the bootstap.groovy
I tried the little "l" for the 'label' and it works... But I don't understand why it doesn't work for the 'L' ...
Do you have some explanations?

Thank you all for your answers,
Hugo

There are many places in Grails that assume you are following the usual
JavaBean conventions where property names are lowerCamelCase and class
names are UpperCamelCase, and some of the conversions between property
names, getter/setter names etc. may break down if you don't stick to this.
