Maybe it's because your second and third dropdowns are taking their
input from the posted parameters (the raw input) instead of from their
model. See the source for FormComponent.getValue():
if (NO_RAW_INPUT.equals(rawInput))
{
return getModelValue();
}
else
{
if (getEscapeModelStrings() && rawInput != null)
{
return
Strings.escapeMarkup(rawInput).toString();
}
return rawInput;
}
After submit, your dropdowns are probably taking the second branch. So
in your updating behavior, try something like:
protected void onUpdate(AjaxRequestTarget target) {
dropDown2.clearInput(); <--- reset input !!!
dropDown2.setModelObject(null);
target.addComponent(dropDown2);
}
This not only sets the second dropdown model to null but also resets its input.
