Doubled text upon table page break when a Tabstop is used

Hi Tommy, here’s a weird bug…

I use Apose.Pdf to generate labels, so I basically do a table with fixed cell dimensions. In those cells, some text has to be right aligned, so I added a right-aligned tabstop. Up to here, everything’s OK. But when the table breaks onto a new page, the left-aligned text (before the tabstop) is duplicated for the first cell of the new page. After that, everything’s back to normal.

Here’s a sample code that illustrates the problem. I tried to keep it as simple as possible, but it’s still long, sorry for that. (attachment is the result)

Thanks,

Dominic.

Hi,

Thank you for considering Aspose.

I will test and solve this problem. This may need several days.

This bug has been fixed in the new hotfix.
