I would recommend to start with a jrxml that includes the max number of columns, and then if user select less columns then find those additional columns in the jrxml and delete them. Variables can be jrxmo to simplify the report design by declaring only once an expression that is heavily used throughout the report design or to perform various calculations on the corresponding expressions.
When a larger group encounters a rupture, all subsequent groups are reinitialized.
They allow the creation of more complex reports and simplify the design work. And yes sure you will be able to create the report dynamically from front end attributes, that’s exactly why DJ is made: See the ScriptletReport sample for more details. For example, if we want to display in a text field, on the report, the concatenated values of two fields, we can define an expression like this one:.
