RE: [wtp-dev] API to get a list of required facets given a "top"facetver

[Jim Zhang <jzhang@xxxxxxxxxx>]

Hi, Konstantin, I can understand your
concern of the scope of this feature.  I added some comments for a
proposal of a minimum solution to the bug entry.  Can you comment
on whether it's feasible, and if so, for 1.0 or 1.0.1?

Regards,

Jim,
 
The following bugzilla entry
is used to track this enhancement request: https://bugs.eclipse.org/bugs/show_bug.cgi?id=115892.
 
The problem is quiet difficult
even if when making assumptions such as “take the highest version”. The
OR constraints have to be dealt with. The list that you compute might not
useable because of other facets currently selected and their constraints
or the limitations of a runtime. In short, in order to make this work we
would need a pretty sophisticated algorithm that’s capable of picking
facets and versions while taking into account everything around it. Is
it ok to change the version of face x that’s already selected to satisfy
my constraint? Maybe it is; maybe it isn’t; maybe following another OR
branch will make changing the version not necessary. It a lot of these
situations, user feedback will have to be involved.
 
Regards,
 
- Konstantin

Subject: [wtp-dev] API to get a list of required facets given a "top"facetversion
 

Hi, currently if a required facet is not selected in the 2nd page of the
project creation wizard, you'll get a messages stating something to the
effect of "missing required facet ABC 1.0".  However there's
no current API support for obtaining a list of required facet (or facet
versions) given a "top facet version".  I understand that
multiple facet versions can fulfill a requirement so there is no unique
list to return.  But at least one list can be accurately calculated:
a list of highest-versioned facets to fulfill a top facet version's requirement.

Why I need such a list is because I want to enhance the 1st page of the
project creation wizard to have some combo boxes to drive the facet selection
on the 2nd page.  One of the things I need to figure out is the required
facet versions list. 

Anybody else see value in such an API?

Regards,
