Stretching band in Jasper

Making a band stretch according to the height of its contents is simple. First you need to have some content that is stretching, for example a text field with “stretch with overflow” property set to true.

For the band you need to set “split type” to stretch. Also make sure you report specifies “print type” to be vertical. To guarantee layout, Jasper does not stretch the fields in the print type is horizontal.

If you have fields in the band below the stretching field, you probably need to change their position type to either float or “fix relative to bottom”. Otherwise they are not moving the field above is stretching and the fields are rendered on top of each other.
