Re: [SQLObject] Return an SResult object from a MultipleJoin

[michelts <mic...@gm...>]

I think on that and I agree, a subclass will be better than edit the
MultipleJoin class, does you have any name suggestion for the class
name? But, in other perspective,  it is the same multiplejoin
anyway... What do you think, for any case is ok.

To switch asList at run time will be a usefull feature, but how can I
call the join as a function?
object=SomeClass.get(1)
object.joinedobjects
object.getJoinedobjects(...) ?

I didn't find a way to know the table style, I will look at the source
again and find a way to use the table style...

I will explain the usage of this feature for me: I have Servlets
(webware) that iterates over the join to show the results, I need to
test the length of the list, this way I think it will be better to use
join.count() instead of len(join)... I will have access to some
functions like sum(), avg(), max(), min()...

Sorry the broken patch :), I'm not so familiar with sqlobject source,
I must give it more time, today I will have this time ;)

thanks for attention and sorry my bad english...
