Question

I’m using GWT on the client side. I store String objects in an ArrayList instance, and when I add the value “AT&T”, it only seems to be storing “AT”. I suspect this is the result of the ArrayList truncating the text due to the ampersand, but I have yet to write a smaller proof-of-concept to be sure. Has anyone else encountered this problem?

GWT 2.1.1
Tomcat 7.0.5
Firefox 5.0.1

So this test succeeds:

        ArrayList<String> test = new ArrayList<String>();
        test.add( "testing&123");
        Window.alert( test.get(0) + " - " + test.get(0).contains("&") );

My code effectively does this:

String test = "AT&T";
MyApp.getInstance().getDataStore().add( test );
Window.alert( test + " - " + MyApp.getInstance().getDataStore().getItems().get(0) );


public void DataStore.add( String item ) {
   itemsList.add( item );
}
public ArrayList<String> getItems() {
   return itemList;
}

The output is “AT&T – AT”. So if the ArrayList is not the problem, is it the method calls?

Well, it turns out it was an interaction between my History Manager and the DataStore class. A very strange situation that no one could have helped me with given the limited amount of information I had provided.
