Subject [jira] [Updated] (FLEX-33409) TLF crashes when hypens are shown in a multi span textFlow
Date Wed, 21 Aug 2013 06:25:52 GMT

     [ https://issues.apache.org/jira/browse/FLEX-33409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Harui updated FLEX-33409:
------------------------------

    Attachment: FLEX33409.patch
                ComposeState.as
                BaseCompose.as

Potential Patch.  You can apply the patch or swap in flashx.textLayout.compose.BaseCompose.as
and flashx.textLayout.compose.ComposeState.as

This appears to be a bug in the player and a bug in BaseCompose.as.

BaseCompose.as got fooled when a linebreak happened on a hyphen because the hyphen retains
a character position and absoluteStart on the following line skips that hyphen, so you can't
find your position by just adding up lengths of lines; you have to factor in the absoluteStart.

But after that, it appears the player can't property start the generation of TextLines from
a TextBlock if you start on a line after a line that ended with a hyphen, so now we also regenerate
the TextLine for the line with the hyphen.

> When soft hyphens are used and shown, in a textFlow with 2 or more spans, TLF crashes
when typing.
> Import the underlying text flow xml. Resize the text area until the hyphen is visible.
Then start typing AFTER the hypened word, also pressing the enter key. TLF crashes.
> Sample textFLow (if the soft hyphen is not show, insert a new one in the appropriate
word):
>   <TextFlow color="#000000" fontSize="12" lineHeight="14" paddingBottom="0" paddingLeft="10"
paddingRight="10" paddingTop="0" whiteSpaceCollapse="preserve" version="2.0.0" xmlns="http://ns.adobe.com/textLayout/2008">
>     <p>
>       <span backgroundColor="#ffffff" textDecoration="underline">First Span</span>
>       <span backgroundColor="#ffffff" textDecoration="none"> Second span. This
text has a hypen in the next long word LongWord­WithAHyphen. Make sure the hypen is shown!
Then start typing and pressing enter till TLF crashes (should happen fast enough)</span>
>   </p>
>   </TextFlow>
> It seems that the textLine is damaged but the text engine fails to recompose the line
properly.
