Adichatz generates brute Entity Editors to display detail parts of an Entity and the list of its related objects (dependencies). For example the Entity Editor for a Film class is described by an XML file called 'FilmEditorGENERATED.axml' or 'FilmDIGENERATED.axml' (see generated file).

For example, open file $projectDirectory/resources/xml/model/film/FilmDIGENERATED.xml.

Following XML elements:

renders the new layout:
Film detail (improved)

Remarks:

Lines 15:A text controller is trplced by an ImageViewer controller which displays an image for an URL.
Lines 29-32:show how to create a dynamic block. 'forRentGroup' pgroup is created only when field forRent is set to true.


If you are using pagila postgresql datababase rather than sakila mysql, two changes must be done:
replace line 25 by following lines. 

<ccombo property="rating" id="rating">
    <labelProvider>
        <textCode>return ((#MODELPACKAGE().MpaaRatingEnum) element).getValue();</textCode>
    </labelProvider>
    <initValues>return java.util.Arrays.asList(#MODELPACKAGE().MpaaRatingEnum.values());</initValues>
</ccombo>

replace line 41 (line 46 after previous change) by following lines. 

<multiChoice popupToolbar="true" multiChoiceType="Array" values="Trailers,Commentaries,Deleted Scenes,Behind the Scenes" property="specialFeatures" id="specialFeatures">
    <convertTargetToModel>return java.util.Arrays.copyOf((Object[]) value, ((Object[]) value).length, String[].class);</convertTargetToModel>
</multiChoice>

See page Improve Film Detail (pagila).


Same method can be used for FilmDescription.
