Debugging the code just tells me the same as the exception does:
CheckGroup.updateModel:
public void updateModel()
{
Collection<T> collection = getModelObject();
if (collection == null)
{
collection = getConvertedInput();
setDefaultModelObject(collection);
}
else
{
modelChanging();
collection.clear();
collection.addAll(getConvertedInput()); <-----
modelChanged();
}
}
getConvertedInput() returns a String instead of a collection instance.
This just has to be wrong, because it returns T, the parameter of
FormComponent<T>, and CheckGroup extends FormComponent<Collection<T>>.
Removing the setType-Call doesn't help.

Have you tried to debug the code where you get the exception? I
suspect that you just have some data types mixed.
Maybe it is just this: comp.setType(parameter.getType()); Is that necessary?
