Hi,

I worked out a 100% reproducaeable example so that we can narrow this issue down:

1)
create new database with the name updateTest

2)

create the following table:

CREATE TABLE `updateTest`.`updateTest` (
`id` INT( 255 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`content` TEXT NULL
) ENGINE = MYISAM ;

3)
drag a datagrid into DesignView

4)

connect to Dataservice via PHP and generate sample classes from the created database

5)

drag 'getAllUpdateTest()' on the datagrid

6)

generate Form from 'createUpdateTest(item:UpdateTest)'
Edit Property Mapping and disable id from inputs (the id will be auto incremented)

Ok now we can add new entries.

7)

Now generate a Form, from 'updateUpdateTest(item:UpdateTest)

When you now try to update one existing entry we get:

Error: Unable to find data service for value: valueObjects::UpdateTest {
  content = "cool"
  id = 1
}

If we call the service with help of the 'TestOperation' Tab, it is working flawless !

Any help is much appreciated, *please* help

Thank you for confirming this issue.

I posted a bug report at:

https://bugs.adobe.com/jira/browse/FB-26384

Please fix

I have meanwhile learned how to use ZendAMF without the wizard

It's much more FLEXible

But you can just create the code automatically and delete the service from the Services,

so that you dont have to write the PHP Code manually 

OK I try to clear it:)

By DataService Wizard I men the following:

http://flashrealtime.com/wp-content/uploads/newfxphp/vyber-technologie -php.png

When you automatically create PHP Services, the communication between Flex and PHP is solved by using the Zend Framework with help of the AMF Protocoll.

Beside the integrated Zend Feature you can use it even manually which gives you more control

e.g: http://corlan.org/2008/11/13/flex-and-php-remoting-with-zend-amf/

Be welcome if you have any further questions.
