3 In the Diva look example, we may add a movie to a Studio by clicking "add" on the Studio edit page:

7 As you can see from the screenshot (above) that adding a movie allows you to edit/insert a movie //inline//.
8 This is achieved using a combination of //ajax// and //dynamic// D2W assignments.
9
10 In this example we add a single rule to achieve this:
11
12 |=(((
13 LHS
14 )))|=(((
15 assignment
16 )))|=(((
17 key
18 )))|=(((
19 RHS
20 )))
21 |(((
22 (pageConfiguration = 'ListEmbeddedMovie' and parentPageConfiguration like '*Edit*')
23 )))|(((
24 **ERDDelayedBooleanAssignment**
25 )))|(((
26 **componentName**
27 )))|(((
28 {"conditionKey" = "object.isNewObject";
29 "falseValue" = "ERD2WDisplayString";
30 "trueValue" = "ERD2WEditString";}
31 )))
32
33 Note that the **ERDDelayedBooleanAssignment** is a somewhat complex rule in that it's RHS value is a dictionary (in plist format).
34 What it says here is if the Movie object is new use an edit string component, otherwise just display the string.
35
36 So the //component// is dynamically assigned - determined by the condition of the object listed. (i.e if it's new or not).
