[jira] [Commented] (PDFBOX-1276) java.lang.NullPointerException on
trying to set value for PDTextBox in pdf file.
[ https://issues.apache.org/jira/browse/PDFBOX-1276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13279669#comment-13279669 ]
Manoj Patel commented on PDFBOX-1276:
-------------------------------------
I found same issue and changed code in PDAppearance as
if( retval == null )
{
retval = (PDFont)formResources.getFonts().get( fontName );
//Bug Fix - START
if(retval == null){
retval = PDType1Font.HELVETICA;
}
//Bug Fix - End
streamResources.getFonts().put( fontName, retval );
}
It's working fine for me.

> When trying to set value for a field in pdf using,

> i.e. intruduced a try-catch for
> retval = (PDFont)formResources.getFonts().get( fontName );
> resolved the issue for me as well.
> Also, I had to add try-catch for following :
> printWriter.println(getTextPosition(boundingBox, pdFont, fontSize, tokens));
> as getTextPosition() is throwing IOException as the pdFont is null.
> Creating this issue so that the bug is documented and would like to see the change in upcoming releases.
> Shall attach the jar file that contains the changes which resolved the issue.
