Roger Whitcomb commented on PIVOT-1021: --------------------------------------- Just so I don't forget it over the weekend: here's what typically happens in the "cut text at the end of a word": (((((((((((((( start of cut )))))))))))))))) Remove a segment of the Paragraph (node offset 0) at offset 13, count 4 Remove a segment of the TextSpan (node offset 8) at offset 13, count 4 Remove a segment of the TextNode (node offset 0) at offset 5, count 4 >>>>> TextPane.rangeRemoved: Document, offset 13, count 4 (((((((((((((( end of cut )))))))))))))))) Note: the "TextPane.rangeRemoved" has no "removed text" along with it, so there is no way to add a history item. We must find a way to provide the removed text in this case. That is the issue. > Undo after delete in TextPane can cause IllegalArgumentException > ---------------------------------------------------------------- > > Key: PIVOT-1021 > URL: https://issues.apache.org/jira/browse/PIVOT-1021 > Project: Pivot > Issue Type: Bug > Components: wtk > Reporter: Roger Whitcomb > Assignee: Roger Whitcomb > Priority: Minor > > Under various conditions (such as selecting an entire word that is a > TextSpan) deleting it with Ctrl/Cmd-X then Undo (Ctrl/Cmd-Z) causes an > IllegalArgumentException: > java.lang.IllegalArgumentException: Child node must be an instance of > org.apache.pivot.wtk.text.Block > STACK TRACE: > at org.apache.pivot.wtk.text.Document.insert(Document.java:45) > at org.apache.pivot.wtk.text.Element.add(Element.java:369) > at org.apache.pivot.wtk.TextPane$RangeRemovedEdit.undo(TextPane.java:134) > at org.apache.pivot.wtk.TextPane.undo(TextPane.java:796) > at org.apache.pivot.wtk.skin.TextPaneSkin.keyPressed(TextPaneSkin.java:1360) > at > org.apache.pivot.wtk.Component$ComponentKeyListenerList.lambda$keyPressed$1(Component.java:477) > at java.lang.Iterable.forEach(Unknown Source) > at > org.apache.pivot.wtk.Component$ComponentKeyListenerList.keyPressed(Component.java:477) > at org.apache.pivot.wtk.Component.keyPressed(Component.java:2711) > at > org.apache.pivot.wtk.ApplicationContext$DisplayHost.processKeyEvent(ApplicationContext.java:1566) > at java.awt.Component.processEvent(Unknown Source) > at > org.apache.pivot.wtk.ApplicationContext$DisplayHost.processEvent(ApplicationContext.java:945) > at java.awt.Component.dispatchEventImpl(Unknown Source) > at java.awt.Component.dispatchEvent(Unknown Source) > ... > Or sometimes an IndexOutOfBoundsException can occur instead (such as doing a > second Undo right after the first). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
