Adobe Flash Builder 4: Data-centric Features for PHP - Page 3

As you can see, there is no reason for a User.php class that wraps all the associated variables and maps to a corresponding Adobe ActionScript class. The values are pulled directly from the $user variable that is sent over as a generic Object using the $user->value syntax.
Drag-and-Drop Data Binding
Make sure you have the Application MXML file open and the Design view selected. Next, drag a VDividedBox onto the stage. Then, drag a DataGrid into it from the Components window. Now select and drag the getAllUsers() method from the Data/Services tab and drop it on top of the DataGrid. Switch to the Source view, and take a look at the new code that was just generated for you.
Now, run the application. Hopefully, without having made any modifications, your browser window displays something similar to Figure 9. Of course, if you didn't bother to take the time to insert data into your database, now might be a good time to go back and do that; then, try running the application again.

Generating a Master Details Form
Next, auto-generate a Master/Details form. With the main MXML application file open, select the Design view again. Then, right-click on the data grid and click Generate Details Form. In the first window that appears, select the form options. Make sure you select Master control from the first drop-down list; the Make form editable check box should already be selected. (Clear this check box if you do not want the details of the selected item in the DataGrid to be editable.) Next, select the Make a new service call to get details check box. The service you created earlier should already be selected. In the Operation drop-down list, select the getUser(userId:String):User[] operation, as seen in Figure 10. When an item is selected in the data grid, the corresponding information will be displayed in the form that appears below it.

After clicking Next, you will see a window that looks like Figure 11. As you can see, the check box for the id property has been cleared so that no ID is displayed in the form. However, you also have the option of displaying the value of a field without making it editable by selecting Text instead of TextInput for the corresponding Control type. Now, click Finish.

When you switch to Code view now, you'll notice that your application file is starting to be somewhat lengthy. Figure 12 demonstrates what the application looks like when an item is selected from the DataGrid.
