>                 URL: https://issues.apache.org/jira/browse/PIVOT-954
>             Project: Pivot
>          Issue Type: Bug
>          Components: wtk
>    Affects Versions: 2.0.4, 2.1
>         Environment: All
>            Reporter: Roger Lee Whitcomb
>            Assignee: Roger Lee Whitcomb
>            Priority: Minor
>              Labels: doubleclick, textarea
>             Fix For: 2.1, 2.0.5
>
>
> Start with an empty TextArea, then double click anywhere (which normally would select the current word), there will be basically an assertion error from here:
> java.lang.IndexOutOfBoundsException: index: index (-1) < min (0)
>         at org.apache.pivot.wtk.Component.indexBoundsCheck(Component.java:2861)
>         at org.apache.pivot.wtk.TextArea.getCharacterAt(TextArea.java:904)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.selectSpan(TextAreaSkin.java:969)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.mouseClick(TextAreaSkin.java:1023)
> The underlying problem is trying to get the character at offset -1 in the document.
> It could also occur in any document in which the first line is empty, and trying to double click there (with a slightly different stack trace):
> java.lang.IndexOutOfBoundsException: index: index (-1) < min (0)
>         at org.apache.pivot.wtk.Component.indexBoundsCheck(Component.java:2861)
>         at org.apache.pivot.wtk.TextArea.getCharacterAt(TextArea.java:904)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.selectSpan(TextAreaSkin.java:974)
>         at org.apache.pivot.wtk.skin.TextAreaSkin.mouseClick(TextAreaSkin.java:1023)
> (This is from the "trunk" version).
