Yes, BIRT report designer explicitly
set the units whenever it set the value for a report element’s dimension property.
If others develop a custom
report designer that does not set the unit, the default unit of this element defined
in ROM will take effect. If it is not defined in ROM, then the one setting on session
handle will take effect. Otherwise, a semantic warning will be thrown. (A dimension
value without unit may cause failure when engine render the report in html and pdf)
If we remove this property
from module, then user can not set general units for a single module any more, he/she
could just set the units on session, or on individual design element.
Even now, the general unit
is not always suitable for all kinds of elements, for example, if user set unit
to be “mm”, but “mm” is not a common unit for font size.
So ROM defines some default units for those that suppose to have their own default
value. The default unit search route is:
ROM
Module
Session
The bug reporter thinks there should be a switch to decide either to use the metric system or the US/English system. But the unit he/she setting on module does not take effect since BIRT report designer has explicitly set units for elements. To avoid confusion, Qiangsheng suggests deprecating this property.

Does
BIRT report designer explicitly set the units whenever it set the value for a
report elements' size property?
Can
others develop a custom report designer that does not set the unit? In
such a usage, is report level "unit" property useful?

There is a
bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=174259,
General settings for "Units" is ignored.
Since the Designer will decide the default units for each kind of element and
it takes higher priority, the one user setting on the report looks ignored.
Now propose to remove the ‘unit’ property from ReportDesign in ROM,
and corresponding API, to avoid confusion.
