Smart GWT Gotchas

1. ListGrid - Change color of a row or individual cell
2. Dynamic Form
           StaticTextItem
3. JSON parsing :
                JavaScriptObject jsObject = JSON.decode(responseData);
                JSONArray accountNames = XMLTools.selectObjects(jsObject, "accounts");
                final JSONValue jsonAccount = accountObjs.get(0);
                final String accountNumber = jsonAccount.isObject().get("AccountNumber").isString().stringValue();
4. Mock Presenter gotcha :

   Caused by: java.lang.UnsupportedOperationException: ERROR: GWT.create() is only usable in client 

     Fix : GWTMockUtilities.disarm();   More here

5. Speed up gwt compile time : here

6. Error processing request: The response could not be deserialized
             Annonying issue in dev mode from eclipse. See that the default compile target is set to ../web-inf/classes in eclipse. Restart eclipse. clean up target classes folder. Got it working...after a redeploy of war again...strange..cant point to one specific thing (as i did clear browser cache/eclipse classes output/restart eclipse)

Apparently workaround seems to be try redeploying app whenever this issue occurs..

7. Wrap text in list grid:
listGrid.setFixedRecordHeights(false);
listGrid.setWrapCells(true);

8. Listgrid pagination related issues(issues with page scroll based pagination):

Serendipity might have already solved the pagination and csv export : http://code.google.com/p/crmdipity/downloads/list

think best if we have traditional pagination approach. and have as PaginatedListGrid which will solve all list grid related issues:
  - sorting
  - export to excel
  - print
  - slow page load
  - less browser load (as only one page of data is available at any point of time)
