Dan Caprioara created FOP-2816:
----------------------------------
Summary: The property keep-together.within-page='always' implies
keep-together.within-column='always' (there should be a difference)
Key: FOP-2816
URL: https://issues.apache.org/jira/browse/FOP-2816
Project: FOP
Issue Type: Bug
Components: layout/page
Affects Versions: 2.3
Reporter: Dan Caprioara
This is an example: A document having two columns and as series of small
sections, called steps. Each of the "step" block has the attributes:
{code:java}
keep-together.within-column="auto"
keep-together.within-page="always"
{code}
The "step" at the end of the first column should break on the two columns, as
it has {{keep-together.within-column="auto"}}. Instead it moves completely to
the second column.
In fact it behaves as the column breaks and page breaks are considered by FOP
to be the same thing.
