> I'm getting frequent NullPointerException's related to selecting in a
> TextPane. Here's a simple example:
> <Window maximized="true" xmlns:bxml="http://pivot.apache.org/bxml";
> xmlns="org.apache.pivot.wtk">
> <TextPane>
> <Document xmlns="org.apache.pivot.wtk.text">
> <Paragraph>
> <Span font="{bold:true}">Important: </Span>
> <Span>I'm getting frequent NullPointerException's related to
> selecting in a TextPane. This is a simple example.</Span>
> <Span font="{italic:true,size:9}"> (Today @ 12:31p)</Span>
> </Paragraph>
> </Document>
> </TextPane>
> </Window>
> Reshape the window small enough that some or all of the italicized text is on
> at least the third line. Now try to select text from the plain part into the
> italicized part. A typical backtrace in my debugger reads:
> java.lang.NullPointerException

> Similar errors occur if you start with the window wide, select text spanning
> the plain and italic parts, and then reshape the window narrower.
> Related bug without a fault: with the window wide, select text spanning the
> bold and plain parts. Reshape the window narrower. You'll get to widths
> where more text appears selected than should be and/or some of the text is
> blank.
