How to persist values in BIRT?
Hi,
I need help saving a value from a row and comparing it with the next row. For example, the report has to show how much time a WI was in a state. (Right now I have how much time a WI was between every save, but I can't persist the first timestamp in order to compare it with the next). Thanks. |
One answer
A BIRT report has an initialization script that runs before anything else. You can declare global variables
there.
Beware, though, as the charting API doesn't see those globals - you have to explicitly share those values in order to use them in a chart context.
