Hey,

trying to use some count constraint on my root element - somehow it does not show any error message if the constraint is violated.

import org.eclipse.sapphire.modeling.IModelElement;
import org.eclipse.sapphire.modeling.ListProperty;
import org.eclipse.sapphire.modeling.ModelElementList;
import org.eclipse.sapphire.modeling.ModelElementType;
import org.eclipse.sapphire.modeling.annotations.CountConstraint;
import org.eclipse.sapphire.modeling.annotations.GenerateImpl;
import org.eclipse.sapphire.modeling.annotations.Label;
import org.eclipse.sapphire.modeling.annotations.Type;
import org.eclipse.sapphire.modeling.xml.annotations.XmlBinding;
import org.eclipse.sapphire.modeling.xml.annotations.XmlListBinding;
import org.eclipse.sapphire.modeling.xml.annotations.XmlNamespace;
import org.eclipse.sapphire.modeling.xml.annotations.XmlSchema;

@GenerateImpl
@XmlNamespace(uri = "http://www.example.org/TestSystem")
@XmlSchema(namespace = "http://www.example.org/TestSystem", location = "http://www.example.org/TestSystem/1.0")
@XmlBinding(path = "root")
public interface Root extends IModelElement {

    ModelElementType TYPE = new ModelElementType(Root.class);

    // *** Description ***
    // @formatter:off
    @CountConstraint(min = 1)
    @Type(base = DescriptionBase.class, possible = { DescriptionA.class, DescriptionB.class, DescriptionC.class, DescriptionD.class })
    @XmlListBinding
    (
        path = "descriptions", 
        mappings = 
        {
                @XmlListBinding.Mapping(element = "a", type = DescriptionA.class),
                @XmlListBinding.Mapping(element = "b", type = DescriptionB.class), 
                @XmlListBinding.Mapping(element = "c", type = DescriptionC.class),
                @XmlListBinding.Mapping(element = "d", type = DescriptionD.class)
        }
    )
    
    ListProperty PROP_DESCRIPTION_BASE = new ListProperty(TYPE, "DescriptionBase");
    
    ModelElementList<DescriptionBase> getDescriptionBase();
    // @formatter:on

    // *** Item ***
    @Type(base = Item.class)
    @Label(standard = "items")
    @CountConstraint(min = 1)
    @XmlListBinding(mappings = @XmlListBinding.Mapping(element = "item", type = Item.class))
    ListProperty PROP_ITEMS = new ListProperty(TYPE, "Items");

    ModelElementList<Item> getItems();
}

If I start with some plain xml file, no error message is given. Both list properties violate the constraint since both have zero children.

The strange part is, that I already use the count constraint on list properties in my application. It is further down in the hierarchy (in the Item.class). Apparently, the count constraint just doesn't work on the root element. Or am I doing something wrong? Thank you.

Best regards,

Kon

Strange. Could you open a bug report and attached a zip of a project showing the problem?

Hey,

I'm updated my editor to Sapphire 0.7 having still the same issue. I was wondering if I could use EL to validate the min size of a list property on the root element. I tried the following update on the items property:

// *** Item ***
@Type(base = Item.class)
@Label(standard = "items")
//@CountConstraint(min = 1)
@Validation(rule = "${Items.Size > 0}", message = "Min. one elemente!", severity = Severity.ERROR)
@XmlListBinding(mappings = @XmlListBinding.Mapping(element = "item", type = Item.class))
ListProperty PROP_ITEMS = new ListProperty(TYPE, "Items");

ModelElementList<Item> getItems();

My problem remains Sad

Am I using it right? Thank you.

Best regards,

Kon

Hey Konstantin,

thank you for the bug fix. With the latest version the error messages are shown as expected.

With the change to 0.7 I noticed that the bundle org.eclipse.sapphire.ui.swt.xml.editor now lists the following dependency:

org.eclipse.jdt.core;bundle-version="[3.7.0,4.0.0)"

I was wondering why this jdt dependencies is required? So far, I was able to avoid any jdt bundles in my application Smile
