Bug in 2.2? Can't get Legend to display on Line Chart

EDIT: Apologies if this post isn't in the right place. I saw the forum was for Integration issues and I've been reading the Integrating and extending BIRT book to help resolve my problem<br />
<br />
Hi,<br />
<br />
I've recently written a Line Chart report, and have set the visibility of all of the series on it to hidden.<br />
<br />
Using a list of report parameters, I perform a string-match check on the report parameter item to enable visibility of user-selected series when the report is loaded.<br />
<br />
Unfortunately, this is not causing BIRT to display the series in the legend. It is still invisible there.<br />
<br />
I have ruled out the possibility that the entire legend is not displaying, as I have set a black border to the legend in the Chart GUI. This border shows, but contains no contents.<br />
<br />
Could anyone help? I enclose code which shows my logic for the enabling of the series for visibility, and my attempt to make the legend item also visible.<br />
<br />
I've read Chapter 11 of Integrating and Extending BIRT, which made me wonder if the legend is there, but just out of sight. However I still am without success.<br />
<br />
Thanks,<br />
<br />
