[jboss-jira] [JBoss JIRA] (DROOLS-4358) line separators in CONDITION column in spreadsheet are escaped

[Toshiya Kobayashi (Jira)]

    [ https://issues.jboss.org/browse/DROOLS-4358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763604#comment-13763604 ] 

Toshiya Kobayashi commented on DROOLS-4358:
-------------------------------------------

If I correctly understand, the current implementation escapes all newlines in Cell values.

If it's difficult to implement "escape newlines only in literal String", one idea is to introduce an option like EscapeNewLines (disabled by default) so that we can minimize the impact to ordinary users.
