Trouble executing "some" auto generated php remote services...?

Question

Hi,
I was using the flash builder 4 premium trial with the 4.0 sdk, recently I bought the CS5 web premium suite. It includes flash builder 4.0.1 standard with 4.1 sdk.
1. create a new flex project (as in the welcome tutorial)
2. create a sample PHP service using my db infos (let it install Zend_AMF for me)
3. place a datagrid in the desing mode,
4. drop the the "getAll()" method on it
5. tweek some columns,
6. it works, I see the service call and answer with service capture (an external AMF service monitor).
the 2 problems that appear now (which were not existing in the 4.0 trial version I had)
1) add a new item
protected var newItem:dbItem;
protected function addBtn_clickHandler(event:MouseEvent):void
newItem = new dbItem();
newItem.attribute = 'someValue';
this.addDbItem(newItem:dbItem);
protected function addDbItem(item:dbItem:void
createDbItemResult.token = dbItemService.createDbItem(item);
<s:Button label="new item" id="addBtn" click="addBtn_clickHandler(event)"/>
When I click the button, absolutely NOTHING happens, no error, no service call, nothing at all.
2) refresh the datagrid's dataprovider
I followed the tutorial on how to bind an ArrayCollection to the dataGrid instead of binding it to "service.lastresult"
populate the ArrayCollection with the service result handler with event.result as ArrayCollection... everything works like before. whe the datagrid is created, it calls the "dataGrid_creationCompleteHandler".
protected function dataGrid_creationCompleteHandler(event:FlexEvent):void
this.getAllDbItem();
protected function refreshBtn_clickHandler(event:MouseEvent):void
this.getAllDbItem();
protected function getAllDbItemResult_resultHandler(event:ResultEvent):void
DbItems = event.result as ArrayCollection;
<s:Button label="refresh" id="refreshBtn" click="refreshBtn_clickHandler(event)"/>
this works!, the refresh button also works, BUT... it only refreshes item which have not bee edited within the app... if I change some item value with a form, (still using skills from the tutorial) :
- the data in the datagrid ARE UPDATED.
- the service.update(item) method DOES NOT EXECUTE (like the create above)
- if I update the DB manualy, ONLY the NON UPDATED rows refresh...
Any idea?
Thank you! I'm stuck here for hours and hours now :-(

I think you are not using the "commit" on the service. By default the Data services are "managed".
Data management features allow you to synchronize adding, updating, and deleting of records in a database. Changes you make in the client application are not written to the server until a "commit" method is called. You can call a revert method to roll back changes made in the client application.
So wherever you update or create add "commit" to the service after adding/updating. for eg.
protected function addDbItem(item:dbItem:void
     createDbItemResult.token = dbItemService.createDbItem(item);
     dbItemService.commit();
