[jira] [Commented] (PIVOT-772) Exceptions thrown when calling
getCharacterBounds of TextArea when incomplete lines exist
[ https://issues.apache.org/jira/browse/PIVOT-772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13069680#comment-13069680 ]

--------------------------------------
Hi Noel,
Thanks for looking at this, and indeed now the exceptions are not showing up, but the Bounds values don't look right either. In particular the "scrollAreaToVisible" doesn't do anything because the Y values of the bounds all appear to be 0 after a while (this is the "Multiple Lines" case):
index=79, bounds=org.apache.pivot.wtk.Bounds [116,19;2x16]
index=81, bounds=org.apache.pivot.wtk.Bounds [4,36;2x16]
index=196, bounds=org.apache.pivot.wtk.Bounds [364,0;2x16]
index=312, bounds=org.apache.pivot.wtk.Bounds [399,0;2x16]
index=431, bounds=org.apache.pivot.wtk.Bounds [413,0;2x16]
index=553, bounds=org.apache.pivot.wtk.Bounds [434,0;2x16]
index=667, bounds=org.apache.pivot.wtk.Bounds [385,0;2x16]
index=784, bounds=org.apache.pivot.wtk.Bounds [406,0;2x16]
index=900, bounds=org.apache.pivot.wtk.Bounds [364,0;2x16]
index=942, bounds=org.apache.pivot.wtk.Bounds [21,0;2x16]
