I generally just write the jrxml files for my reports, but I will sometimes use iReport to make placement adjustments.
This first artifact is sort of a feature request: why does iReport always create a <box> element? I use a style attribute to control my display (e.g. borders, etc.), but after I run iReport and save the jrxml file, I end up with <box> for every field and if I want to make a quick change to my style, it has no effect because the <box> specs have taken over.
This second artifact is a bug, I think: when my style has just border="1Point" and borderColor="somecolor", I end up with all borders set to "None" and colors set to #00000 in the <box> so I lose all my borders of my report.
