Hello,
I'm using Eclipse RCP 4 and I've little problem with my WritableValue:
I use the WritableValue in a data binding (see below) and whenever I set the value of my WritableValue with an object that contains an int attribute (part of the binding), then I receive a ClassCastException:
WritableValue<PlantBE> writableValue;
...
writableValue.setValue(somePlantBEEntity)
Caused by: java.lang.ClassCastException: Cannot cast java.lang.Integer to int
at java.lang.Class.cast(Unknown Source)

at org.eclipse.core.databinding.observable.value.WritableValue.doSetValue(WritableValue.java:94)
at org.eclipse.core.databinding.observable.value.AbstractObservableValue.setValue(AbstractObservableValue.java:60)
This is my binding:
IObservableValue<?> model2 = PojoProperties.value(PlantBE.class,
"maxAge").observeDetail(writableValue);
ISWTObservableValue<String> view2 = WidgetProperties.textText(SWT.Modify)
.observe(getDialogView().getTxtMaxAge().getText());
this.getDataBindingContext().bindValue(model2, view2);
The Entity (PlantBE) looks like that:
public class PlantBE implements Serializable {
private int maxAge;
public int getMaxAge() {
return maxAge;
}
public void setMaxAge(int maxAge) {
this.maxAge = maxAge;
}
}
It would be great to get some help on that. Maybe you've an idea what the issue could be.
Thanks and best regards

Thanks for your reply.
I'm using Kepler 4.3.2 as a target platform. The included plugins look like that:
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Require-Bundle: javax.inject;bundle-version="1.0.0";visibility:=reexport,
org.eclipse.swt;bundle-version="3.102.1";visibility:=reexport,
org.eclipse.jface;bundle-version="3.9.1";visibility:=reexport,
org.eclipse.core.runtime;bundle-version="3.9.100";visibility:=reexport,
org.eclipse.osgi;visibility:=reexport,
org.eclipse.e4.core.di;visibility:=reexport,
org.eclipse.e4.ui.model.workbench;visibility:=reexport,
org.eclipse.e4.core.commands;bundle-version="0.10.2";visibility:=reexport,
org.eclipse.e4.tools.services;visibility:=reexport,
org.eclipse.e4.ui.workbench;visibility:=reexport,
org.eclipse.e4.core.contexts;visibility:=reexport,
org.eclipse.e4.ui.services;bundle-version="1.0.1";visibility:=reexport,
org.eclipse.e4.ui.di;bundle-version="1.0.0";visibility:=reexport,
org.eclipse.e4.ui.workbench.addons.swt;bundle-version="1.0.2";visibility:=reexport,
org.eclipse.e4.core.services;bundle-version="1.1.0";visibility:=reexport,
org.eclipse.core.jobs,
org.eclipse.jface.databinding;bundle-version="1.7.0";visibility:=reexport,
org.eclipse.core.databinding;bundle-version="1.5.0";visibility:=reexport
org.eclipse.core.databinding.beans;bundle-version="1.5.0";visibility:=reexport,
org.eclipse.core.databinding.property;bundle-version="1.5.0";visibility:=reexport,
So maybe I'm using the wrong plugin combination. I was trying to chose always the newest version.
Best regards,
Florian
