Question

i have a jlabel and using netbeans i have bound it to a property on the form.

the problem is how do i refresh the binding values when the property that the label text has been bound to has changed.
this.firePropertyChange works but smells bad… i would like someonething like this.bindingGroup.refresh or this.refresh that will update the labels text

for example
the jLabel.text is bound to form someValue

private someClass someThing;
public String getSomeValue(){
  return someThing.getSomeThing();
}
//when someMethof is fired the jlabel should update its text value
public void someMethod(){
  someThing = someThingElse;
  bindingGroup.refresh()?????

}

Unfortunately if you want to use the Beans Binding API, you’ll have to deal with the smell of firePropertyChange.

However, I don’t see what the problem is? It’s quite a simple change. Change your class to the following:

private someClass someThing;
public String getSomeValue(){
  return someThing.getSomeThing();
}
//when someMethof is fired the jlabel should update its text value
public void someMethod(){
  someClass oldValue = someThing;
  someThing = someThingElse;
  this.firePropertyChange("someValue", oldValue, someThing);

}
