Hi I am still new to the GWT toolkit; but I am trying to convert an
old web application into a RIA, using gwt.
One problem I have run into is, that The application includes a form,
where I have an autocomplete function on
some textbox'es and a textarea.
For the autocomplete, I use a PopupPanel wi
What i do is i add hidden inputs to the form i'm submitting along with
my picture, like so
private Hidden formTime = new Hidden();
private HorizontalPanel formHP=new HorizontalPanel();
public FormPanel uploadForm=new FormPanel();//form
formTime.setName("time");
formTime.setValue(""+picTime);
Hi,
I just upgraded to GWT 2.0.3 from within Eclipse (I use the Google

Hello, I'm using a flex table with some Label widgets and an Anchor

When i select a row (when i click on a label), the table has a click

well i found the answer:

with it you can have different classes for server and client.
and it is how GWT provides JRE classes on the client.

Hi All,
I have upgraded my application from GWT1.5.3 to GWT2.0 successfully.

Will it be required to write/change number of classes for the use
Regarding the source of HandlerManager, if i have a custom event and
handler (CellClickEvent and CellClickHandler with
onCustomCellClicked() let's say...) when i instantiate HandlerManager
handlerList = new HandlerManager(flexTable) , fire the event with
handlerList.fire(new CellClickEvent(...)) ,
I guess you must add the fileupload to the form - not to the panel
so call: form.add(fuAppSrcZip);
