Setting Up a Master-Detail Conﬁguration

109

1. In the MovieDetails component window, add the bolded text Starring:

beneath the Revenue line.

2. Below the Starring label, add a repetition.

3. Replace the “Repetition” text with three string elements.

The strings should all be on the same line, so don’t type carriage

returns between them.

4. Type a space between the ﬁrst two strings and the word

“ as ” (with a

space before and after) between the last two.

5. Add a carriage return after the last string.

Conﬁguring a Repetition

Now conﬁgure MovieDetails’ repetition in a way similar to the way Main’s

repetition is conﬁgured. First you need to create a new variable to bind to

the repetition’s

item attribute.

1. Use the Add Variable/Method command to add a new variable,

movieRole,

whose type is set to the MovieRole entity.

Don’t create set and get methods for

movieRole. You won’t need accessor

methods because the variable is used only within the MovieDetails

component and shouldn’t be visible to any other classes.

2. Bind

movieRoleDisplayGroup.displayedObjects to the repetition’s list attribute.

3. Bind

movieRole to the repetition’s item attribute.

4. Bind

movieRole.talent.ﬁrstName to the value attribute of the ﬁrst string in the

repetition.

5. Bind

movieRole.talent.lastName to the value attribute of the second string.

6. Bind

movieRole.roleName to the value attribute of the last string.
