---------------------------------------
Summary: Action method taking domain object paramater gets
triggered automatically whenever instances of that object type is accessed
Key: ISIS-801
URL: https://issues.apache.org/jira/browse/ISIS-801
Project: Isis
Issue Type: Bug
Reporter: Ranganath Chittari
Assignee: Dan Haywood
Priority: Critical
I have application security service which creates permission to manage
particular entity(OmSite). Its action method is:
@Bookmarkable
@MemberOrder(sequence = "9")
@Named("Create Site Permission")
public OmPermission createSitePermission(final @Named("Choose a site")
OmSite site) {
final OmPermission obj = newTransientInstance(OmPermission.class);
obj.setPermission(SecurityUtil.formatSitePermission(site.getOrgId(),
site.getSiteId()));
obj.setSite(site);
persistIfNotAlready(obj);
return obj;
}
As you can see this method takes OmSite instance to create a permission to that
instance. And OmPermission has foreign key to OmSite. This action is displayed
in service menu and its working fine.
But the problem I am facing is when I access the list of OmSite objects in
other UI pages. This action method is getting triggered automatically and
inserts bulk OmPermissions for all those List<OmSite> objects.
This action method createSitePermission should be invoked only if it is clicked
manually, but it gets triggered automatically whenever OmSite is accesed in
some other places.
For ex:
an action that returns a list of these OmSite,
when OmSite is in a collection of some other entity,
When new OmSite is created.
Workaround for this issue is annotate @NotContributed to that action method,
it will prevent from invoking this method whenever its parameter instance is
accessed.
