Page Footer not Expanding

[pradiptab]

Hi

I have placed one field in page footer. And set the property "stretchWithOverFlow" and minimized the band height with the height of the field which is 20 pixels. The field can contain more than 1 line of data. But the footer never expands. If I leave lots of blank space below to the footer field, it expands upto that blank space(when required). But that way it don't look good when the field contains only single line of data.

Is this an issue or i am missing some thing ?

I am using iReport 4.0 to design the report. Please help.

Thanks,

Pradipta
