问题 I'm trying to make my first steps with JasperReports and iReport. Recently I solved a problem with Database Connection in this post.

问题 I have a report made in iReport . I included a textFieldExpression in the column footer. My problem is that even though the line is blank it still takes up the space of the height of the band and thus sending the rest of fields to another sheet.

问题 I use Jaspersoft iReport for generating reports. For passing parameters we need to enter the values in the prompt box during runtime. Can we load up the prompt box with values in a field.
