Hi there,
Thanks for your reply. Yes my initial reaction is indeed "but i
can't". I should have stated that the code I provided before is in an
inner class, and the callback command is outside of this class.
Therefore, if i place the second loop outside of this class it wont be
able to call the data. This si the full code:
AsyncCallback callback = new AsyncCallback()
{
public void onFailure(Throwable caught)
{
updateItemsRootPanel.add(new HTML("Failed:" +
caught.getMessage()));
}
public void onSuccess(Object result)
{
ServerSQLData data = (ServerSQLData) result;
categoryList.clear();
for (int i = 0; i<data.itemCategoryArrayList.size();i++){
System.out.println("Number: " +i);
categoryList.addItem(data.itemCategoryArrayList.get
(i).toString());
}
}
};
class ServerStatsUpdater extends AbstractAsyncHandler
{
public void handleFailure(Throwable caught){
}
public void handleSuccess(Object result){
ServerSQLData data = (ServerSQLData) result;
try{
for(int i = 0; i<typeList.getItemCount(); i++){
if(data.itemType.equals(typeList.getItemText(i))){
typeList.setSelectedIndex(i);
if(data.itemType.toString().equals("Drink")){
changedTypeValue =
typeList.getValue(typeList.getSelectedIndex
());
ServerService rpc = new
ServerService();
rpc.getItemCategoryData(changedTypeValue, callback);
}
}
}
}
catch (Exception e){
System.out.println("Modify: " +e.getMessage());
}
for(int i = 0; i<categoryList.getItemCount(); i++){
System.out.println("Category Count: " +i );
if(data.itemCategory.equals(categoryList.getItemText(i)))
{
categoryList.setSelectedIndex(i);
}
}
I cant see how I am going to get this to work. Surely there must be a
way around?!
Regards,
Jack
