Given:
| @DataModel("displayableCategoryDatamodel")
| private LinkedHashSet<DisplayableCategory> displayableCategorySet;
|
| @DataModelSelection("displayableCategoryDatamodel")
| private DisplayableCategory selectedDisplayableCategory;
|
| @DataModel("keywordsDatamodel")
| private LinkedHashSet<Keyword> keywordsSet;
|
| @DataModelSelection("keywordsDatamodel")
| private Keyword selectedKeyword;
|
| |
| |
| | The first time a member is added to keywordsSet and a page is displayed using the
Datamodel then I get this:
