Hi,
I am looking for a solution for the following situation.
I have 2 wiki's. The fist one (ref: MD) contains "Master Data". The
second one (ref: UD) contains "User Data". I have Classes in UD that use
data from the MD. The way to connect them is using DBList. I am however
not able to compose a HQL query that enables me to select a different
Wiki to run the query on. I know it is possible to select the Wiki in
Velocity but until now, that didn't help me. In the Github code (the
getDBList method in the DBListClass.java) a comment is included just
before a statement:
// The DBlist may come from an other wiki
StringwikiName =getReference().extractReference(EntityType.WIKI).getName();
This might indicate that selecting a wiki might be an option when
getting a DBList.
Anybody knows how to solve this problem (without replicating the data
from MD in UD ;-))? Any additional suggestions are welcome.
Thanks,
Peter

Hi,
The method you are mentioning is used to list the available options, thus
to run the query. The code you mention with the comment was added in order
to make sure that if you are on wiki A and you are getting objects from a
document in wiki B (through velocity for example) and you want to display
those objects from wiki B, then the DBList properties of those objects will
run their queries on wiki B (where their class comes from) and not in wiki
A (where they are called from/displayed).
I also tried to do something similar to what you want, but found that this
is not yet supported by DBList properties.
What you could do at this point is to have a custom displayer for your
property that runs the query on the right wiki and displays the current
value(s) and the possible values.
Hope this helps,
Eduard

I don't know if this is the case for you but you should know that
classes cannot be used outside the wiki where they are defined. In
your case, you cannot add an object of type (class) T to a page from
UD if T is defined in MD.
But I guess you just want to link an object from UD to an object from
MD through a DBList property, which is a different story, covered by
Eduard's reply.
Hope this helps,
Marius
