Hello,
I have two scripted datasets dA and dB. They are bound to two tables tA
and tB.
Table tB is nested into table tA and the rows in table tB depends on the
outer row of table tA which is processed.
I have seen that I can use dataset parameters to pass information between
the two datasets. However, these parameters can only be simple types
(String, Integer, ...). Is there a way to pass more complex information
between the two datasets?
I tried to used the AppContext but it seems like BIRT performs all the
"fetch" operations on dataset A before doing the first "fetch" operation
on dataset B. This means that I cannot store information on the current
row which is being processed in dataset A in the AppContext (or I would
end up with a huge amount of information in the AppContext before dataset
B got a chance to read it).
Are my assumptions correct?
Does anyone have a suggestion on how to pass complex information between
the datasets?
Thanks for your help.
Nicolas
