We also stumbled upon what seems to be the same issue. We tracked it down to javascript in iOS6 behaving strangely in the canCastUnsafe method that is used whenever a java typecast is done. In our case, this only happend when attempting to cast a String value and it only seems to happen in relation to calling Map.get or Map.containsKey with a String key. We haven't found any trivial way of reproducing the issue.
Further details as well as the GWT patch we used to workaround the issue can be found at http://dev.vaadin.com/ticket/10753. We could submit the same patch to GWT, but considering the potential performance implications of the change, we are still investigating alternatives. /Leif -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
