This is a little confusing question to express, its probably more Java then gwt specific, but given that gwt is really javascript, I am not quite sure what domain it falls under.
So ArrayList<Object> fieldList = new ArrayList<Object>(); I then dump a lot of different variables to this array. fieldList.add(ObjectsURL); //string fieldList.add(X); //int fieldList.add(Y); //int ... If I change the variable, the values in the array change too...confirming the array stores a reference to the memory, rather then value itself. However, if I then retrieve data from the array then set that... Object object = ((String)this.fieldList.get(0)); Then set object object = "meeep!" ObjectsURL is not set to "meep!" but rather it retains its original value. I assume this is because the "object" is not referencing the original variable anymore, that instead its pointing to a new immutable string in the memory. All expected Java behavior I think....but then, how would I go about setting the actual original variable? is this possible in java? (is it possible in javascript?). If not, is there an alternative method to achieve the same thing? I hope my question explains the problem well enough. My use-case is trying to make a client only serialization/ deserialization system for a bunch of my objects. I was hoping to put all the fields into a arraylist I could retrieve for both reading and writting....thus avoiding having to hard-code long lists of field[0]=blah and blah=field[0] and then going though constant pains of needing to renumber them each time I add a new field before another. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
