I'm attempting to manually control the paging on a report that is made up of a List with one group. The group band has a grid for the Headings of the group. The Detail band then has a grid that then contains a table holding a sub-report, the sub-report having its own headings. In the initialize event I have the following code:
initHght=.65; // This represents the height of the Master Page Header.
hght=initHght;
maxHght=11.00;
Then, on each printable row, I have the following code in the onCreate event:
rowHeight = this.height;
rowHeight = rowHeight.replaceAll("in","");
rowHeight = rowHeight.trim();
dRowHeight = new Double(rowHeight);
hght = hght + dRowHeight.doubleValue();
Where I would expect/allow a page-break, I then have this code as well in the onCreate.
if (hght>=maxHght)
{
hght=initHght;
this.getStyle().pageBreakBefore = "Always";
}
A few questions.
I have the Height property for my List detail row set to .2 inches. However, displaying the accumulated height for these rows shows that .4 is being added to each row rather than .2. Can anyone explain what's causing this?
Also, I'm getting a page break before I reach the maxHght of 11.00 even though there is still plenty of white space at the bottom of the page. Apparently this is being automatically forced by BIRT since on the next page, the displays of the accumulated height continues where it left off. (Why does BIRT do this automatically?) However, then after continuing for several more rows, my maxHght is reached because I see the variable hght re-initialized but there is no pagebreak. Why wouldn't I get my pagebreak in this instance?
I know this is rather esoteric and definitely not what how I want to be spending my time but once one creates a more complicated report, BIRT doesn't seem to provide the desired paging that I get without effort on my part in some of the other tools I've used in the past. I've attached a copy of the report...the display at the end of each row is for the accumulated height to that point in the report.
I'm using BIRT 2.3.2.
Thanks for any help you can provide.

Paging code in BIRT has undergone many changes since 2.3. Do you have
the option of upgrading? BTW how are you running the report?
