Since a few months I get these errors in our log file. It has something to do with the document generation, but I don’t have a clue where to search for the problem. Has anyone seen these messages before? Sep 19 08:21:45.497 - WARNING - org.apache.fop.apps.FOUserAgent: The following feature isn't implemented by Apache FOP, yet: table-layout="auto" (on fo:table) (See position 2:1791) Sep 19 08:21:45.499 - WARNING - org.apache.fop.apps.FOUserAgent: The following feature isn't implemented by Apache FOP, yet: table-layout="auto" (on fo:table) (See position 9:870) Sep 19 08:21:45.502 - WARNING - org.apache.fop.apps.FOUserAgent: The following feature isn't implemented by Apache FOP, yet: table-layout="auto" (on fo:table) (See position 28:155) Sep 19 08:21:45.502 - ERROR - org.apache.fop.apps.FOUserAgent: Invalid property value encountered in text-align="Left": org.apache.fop.fo.expr.PropertyException: null:28:313: No conversion defined Left; property:'text-align' (See position 28:467) Sep 19 08:21:45.503 - ERROR - org.apache.fop.apps.FOUserAgent: (1/159) org.apache.fop.fo.expr.PropertyException: null:28:313: No conversion defined Left; property:'text-align' Sep 19 08:21:45.503 - ERROR - org.apache.fop.apps.FOUserAgent: (2/159) #011at org.apache.fop.fo.properties.PropertyMaker.make(PropertyMaker.java:446) Sep 19 08:21:45.503 - ERROR - org.apache.fop.apps.FOUserAgent: (3/159) #011at org.apache.fop.fo.PropertyList.convertAttributeToProperty(PropertyList.java:413) Sep 19 08:21:45.503 - ERROR - org.apache.fop.apps.FOUserAgent: (4/159) #011at org.apache.fop.fo.PropertyList.addAttributesToList(PropertyList.java:321) Sep 19 08:21:45.503 - ERROR - org.apache.fop.apps.FOUserAgent: (5/159) #011at org.apache.fop.fo.FObj.processNode(FObj.java:122)

Yes that is document generation using document templates. In production I always set the logger org.apache.fop.apps.FOUserAgent to Error to get rid of these errors. The library spits out logs by the bucket load. If your document is generated correctly, don't worry too much about these. If something is incorrect, these logs could actually be of some help because they can also indicate typo's in custom styling or overlapping elements. So during development you may want to look closer into these.
Try if you can pinpoint when and where this happens. In the stackoverflow question it seems to be with downloading something, so indeed document generation.
