Just tried a sample application on GAE with a HorizontalSplitPanel, was surprised to see a NotSerializable exception @ com.vaadin.terminal.gwt.client.ui.splitpanel.AbstractSplitPanelState$SplitterState
Any reason why this class was not serialized?
However, after overriding the getState() to replace the SplitterState with its serializable subclass, the exception is no longer thrown. But on page refresh the position (width of the components) is lost. In other words I had added 2 vertical panels to the HorizontalSplitPanel, on refresh the second panel disappears and the loading icon gets red @ the top right corner.
Has anybody come across similar issue? Any suggestion would be really helpful.
Has anybody come across similar issue? Has it got some thing to do with my code? - my application hardly has ~20 loc with just 3 simple components. Am I missing any configuration here?
Is there any Vaadin7 demo application (sampler) deployed in app engine?
