From: Jeremias Maerki Date: Thu, 19 Jan 2006 15:10:14 +0000 (+0000) Subject: Following a clarification by the XSL FO SG, space traits are only set on the first... X-Git-Tag: fop-0_92-beta~195 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=4a34763794b0293bbcf74a08f34d0035aeff61fe;p=xmlgraphics-fop.git Following a clarification by the XSL FO SG, space traits are only set on the first and last area generated by an FO, and not on every area anymore. For details, see: http://wiki.apache.org/xmlgraphics-fop/XslFoSpecificationUncertainties/SpaceTraits Note: this change brings another issue in column balancing to light. That's the reason for disabling one of the tests. I wasn't able to find a quick fix there. git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@370494 13f79535-47bb-0310-9956-ffa450edef68 --- diff --git a/src/java/org/apache/fop/layoutmgr/BlockContainerLayoutManager.java b/src/java/org/apache/fop/layoutmgr/BlockContainerLayoutManager.java index 455a7d8fc..658a92e0d 100644 --- a/src/java/org/apache/fop/layoutmgr/BlockContainerLayoutManager.java +++ b/src/java/org/apache/fop/layoutmgr/BlockContainerLayoutManager.java @@ -129,8 +129,8 @@ public class BlockContainerLayoutManager extends BlockStackingLayoutManager this.discardBorderAfter = false;
