Re: cannot deserialize arraylist - but why?

Hi,

I think Class of the object your want to send via GWTRPC must have default constructure. And, if you are putting different kind of objects in one linked list, it will not be deserialised. I faced this issues long back and I am not very sure about the solution ...

how to find out what exactly is causing the error? the arraylist itself obviously cannot be the problem, i've sent a lot of them back and forth.
everything the list contains implements isserializable...
