[jboss-user] [JBoss Seam] - DataBinderClass, DataModel and SelectItems
This confuse me:
In my class (SelectItems from petemuir, before refactor):
| @DataModel
| List actions;
|
| @DataModelSelection
| Action action;
|
| @SelectItems
| List actors;
|
On startup:
| java.lang.IllegalStateException: Missing value() for @DataModelSelection with multiple
@DataModels: assetCustodyFiling
| at org.jboss.seam.Component.initMembers(Component.java:598)
| at org.jboss.seam.Component.<init>(Component.java:248)
| at org.jboss.seam.Component.<init>(Component.java:203)
| ...
|
I think: well... this is impossible... or not?
Then I dig in class Component:
| {
| if ( ann.annotationType().isAnnotationPresent(DataBinderClass.class) )
| {
| dataModelGetters.add(method);
| dataModelGetterAnnotations.put(method, ann);
| }
| if ( ann.annotationType().isAnnotationPresent(DataSelectorClass.class)
)
| {
| selectionSetters.add(method);
| dataModelSelectionSetterAnnotations.put(method, ann);
| }
| }
|
| // ...
|
| final boolean hasMultipleDataModels = dataModelGetters.size() +
dataModelFields.size() > 1;
| // ...
|
| if ( hasMultipleDataModels )
| {
| throw new IllegalStateException( "Missing value() for
@DataModelSelection with multiple @DataModels" );
| }
|
And in petemuir's code:
| @Target({FIELD, METHOD})
|
| @Retention(RUNTIME)
|
| @Documented
|
| @DataBinderClass(SelectItemsBinder.class)
|
| public @interface SelectItems
|
| {
| ...
|
Then, my universe become normal again....
I know that DataModel is the only Seam supplied annotation using DataBinderClass, but is
not wrong assume that for all?
