Sven Meier updated WICKET-5518:
-------------------------------
Description:
FormComponent.updateCollectionModel should handle situation, when getter
returns unmodifiable list.
Proposed solution:
formComponent.modelChanging();
booelan isChanged;
try {
collection.clear();
if (convertedInput != null)
{
collection.addAll(convertedInput);
}
isChanged = true;
catch (Exception e)
{
// ignore this exception as Unmodifiable list
does not allow change
logger.info("An error occurred while trying to
modify list attached to " + formComponent, e);
}
try
{
formComponent.getModel().setObject(collection);
isChanged = true;
}
catch (Exception e)
{
// ignore this exception because it could be
that there
// is not setter for this collection.
logger.info("An error occurred while trying to
set the new value for the property attached to " + formComponent, e);
}
// at least one update method should pass successfully
if(isChanged)
formComponent.modelChanged();
else
throw new RuntimeException("An error occurred
while trying to modify value for the property attached to " + formComponent)
