[jira] [Commented] (FOP-2481) AssertionError at BalancingColumnBreakingAlgorithm.getInitialBreaks
[ https://issues.apache.org/jira/browse/FOP-2481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17450722#comment-17450722 ] TLX commented on FOP-2481: -- Okay, I found the answer myself: A block-container that contains only absolutely positioned children counts as empty to the algorithm. That way it will crash everything by leading to that AssertionError. Solution: Assing span="all" to that block-container. By doing so it won't trigger the column-distribution algorithm. It would be great if this could throw a regular exception that explains what's wrong. AssertionErrors shouldn't be used to catch invalid user input. > AssertionError at BalancingColumnBreakingAlgorithm.getInitialBreaks > --- > > Key: FOP-2481 > URL: https://issues.apache.org/jira/browse/FOP-2481 > Project: FOP > Issue Type: Bug >Reporter: Simon Steiner >Priority: Major > Attachments: exception.fo > > > AssertionError > at > org.apache.fop.layoutmgr.BalancingColumnBreakingAlgorithm.getInitialBreaks(BalancingColumnBreakingAlgorithm.java:171) > export FOP_OPTS=-ea > fop exception.fo out.pdf -- This message was sent by Atlassian Jira (v8.20.1#820001)

All I did was define a 2-column layout with a "span='all'" block-container in it. None of them is empty, which is different from the example file here in this ticket. I really have no idea how to work around this. My .fo data is valid in my opinion. I don't want to turn of assertion checking for my whole application server either. The code in BalancingColumnBreakingAlgorithm.getInitialBreaks as well as the explanation by [~adelmelle] are making me suspect it wouldn't help anyway. > AssertionError at BalancingColumnBreakingAlgorithm.getInitialBreaks > --- > > Key: FOP-2481 > URL: https://issues.apache.org/jira/browse/FOP-2481 > Project: FOP > Issue Type: Bug >Reporter: Simon Steiner >Priority: Major > Attachments: exception.fo > > > AssertionError > at > org.apache.fop.layoutmgr.BalancingColumnBreakingAlgorithm.getInitialBreaks(BalancingColumnBreakingAlgorithm.java:171) > export FOP_OPTS=-ea > fop exception.fo out.pdf -- This message was sent by Atlassian Jira (v8.20.1#820001)
