Bit of a delay on this, but anyway... the good news is that it IS possible
to suppress a contributed action on one parameter but not another.
I've updated the kitchen sink app [1] to show how
In the "contrib" package there are three entities:
* Person [2]
* Preference [3]
* FoodStuff [4]
eg Mary LIKEs Apple, Mungo HATEs Banana, Midge LOVEs Oranges
Neither Person nor FoodStuff knows about Preferences; the Preference is the
tuple that associates the two together.
The PreferenceContributions [5] service provides:
* "likes" - contributed collection to Person
* "firstLove" - contributed property to Person
* "addPreference" - contributed action to both Person and FoodStuff
- "removePreference" - contributed action to both Person and FoodStuff
However, although "addPreference" and "removePreference" *are* contributed
to all parameter types, this can be hidden using the .layout.json file. In
FoodStuff,layout.json [6] we have:
"actions": {
...
"removePreference": {
"actionLayout": {
"cssClass": "btn-warn",
"hidden": "EVERYWHERE"
}
}
}
which means that the "removePreference" action cannot be seen when viewing
a FoodStuff entity.
I'll add this stuff to our website for future reference.
Cheers
Dan
