Dynamic height of element depends of another element

[roston]

 So I have some problem with jasper report. 

My issue about dynamic height of some element, that depends on another element. 

In details:

 

I have table of two cells.

 

And in first cell, I have 4 frame elements. Like

 

    ++------------------++-------++--------++

    ++Program info++Units++Totals++

    ++------------------++-------++---------++

    ++                     COMMENT             ++

    ++-----------------------------------------++

 

So Program info is one frame, Units and totals another, and comment, one another.

So problem. One product could have of not comment, so I set printWhenExpression to Comment Frame. But when product have no comment there is blank place, but I want to increase height of Program info, Units, Totals frames for aligning, or stretch frames down, and I don't want to have blank place in my reports. How I can do this?!

Have you tried giving Comment properties "Remove Line when blank" and giving the other items properties "Stretch Type - Relative to band height"?

[roston]

yeap. but it still don't work. The place of Comment is blank, at it displayed as blank place in my pdf file

Then try using an expression for the program info, units and totals fields. something in the line of 'when comments is blank, program info height = "hard coded maximum band height"'
