[rules-users] Creating custom selectors using the "category" property for deploying certain rules in guvnor

[Premkumar Stephen]

Hi Jaroslaw,


I voted for https://jira.jboss.org/jira/browse/GUVNOR-109
and added the following comment:
<<
+1 for this request.
The ability for users to choose among which selectors are available is
awesome.

Here's an extra requirement that I am bringing forward, not sure what the
complexity on this is:
The list will be populated based on user permissions of some kind.
ie, not all the users can deploy production rules, but all can deploy QA
rules, for example.
>>

I have also created https://jira.jboss.org/jira/browse/GUVNOR-392 for
including categories as a field for filtering.

Regarding your tip on using the 'status' field, I was planning for the
workaround, though it messes with the actual value of this field which i was
planning to use.
Based on our environment, we might actually use the "author" field as
currently there will not be many authors and we are tracking functionality
by using categories anyways.

I have the following questions that are still unanswered:
1) I am trying to figure out where the code for "statusDescription" is?
2) You have suggested 'categorySummary'  - was wondering where these fields
are configured.
3) the minimal documentation in selectors.properties tells only about the
fields status, lastModified date and author, and ends with etc. Could one of
the devs kindly post ALL the fields that could be used?

Regards,
Prem
