Why do I lose textfield text over a page break using iReport?

[bweaver2]

 

I am using iReport 4.7.1.

I have a report which prints out a thread of email messages.

When I set the report to use 'Ignore Pagination' the report works properly (because there are no page breaks to mess up the data)

When I set the report to not 'Ignore Pagination' then over each page break I lose about 2 lines of text. 

 

To replicate: 1) Have text fields in the detail band of a report set to 'Stretch with overflow.' Print large amounts of text into these so that you trigger a page break. If your page break occurs in the middle of a paragraph you will lose date over the page break. 

 

For reference here is my XML:

So I found this link after I posted this with the answer I needed. http://community.jaspersoft.com/questions/507861/losing-some-text-page-break

Here's the gist of what happened:

I was using a font that was not installed on my server. So, this caused the server to use a different font that what was specified the report. iReport calculates text usage on a per page basis before actually generating the report. So the font I wanted to use put 100 lines of text on a given page but the final version generated using the default font on my server could only fit 98 lines into the same space. This is what caused  the problem.

So to fix this I simply switched the font used in iReport to one of the fonts I knew I had installed on my server.
