How to serialize ObservableList
<p>I am working on a <strong>javaFx</strong> project where we have to use <code>ObservableList</code> to add Listners. <code>ObservableList</code> includes Model of persons. But I want to <strong>store</strong> the whole <code>ObservableList</code> Object in a file through serialization. But it <strong>gives me an Exception</strong>.
I also implimented Serialization on the object Model but no luck. Is there any method to serialize <strong>ObservableList</strong>?</p>
