[news.eclipse.birt] PDF Export visibility problem

[gravy@xxxxxxx (Gravy)]

Hello,

i've found this problem: i have simple report with header, which contains 
one grid. Grid has set visibility like this:

reportContext.getAppContext().get("XX")==null

The grid should not render when the context parameter is set. When i run 
this report using report viewer in PDF, the grid is not there, thats ok. 
When i run it using Engine API, it renders, Here is my code which i use to 
set rendering options:

RenderOption renderOption = null;
if(format.equals(ReportingEngine.PDF)) {
   renderOption = new PDFRenderOption( );
   renderOption.setOption( IPDFRenderOption.PAGE_OVERFLOW, new Integer(
           IPDFRenderOption.OUTPUT_TO_MULTIPLE_PAGES ) );
   renderOption.setOption( IPDFRenderOption.PAGEBREAK_PAGINATION_ONLY,
           Boolean.TRUE );
} else {
   renderOption = new HTMLRenderOption( );
   ((HTMLRenderOption)renderOption).setEnableAgentStyleEngine(true);
}
renderOption.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF" );
// If not excel format, set HTMLPagination to true.
if ( !format.equals( ReportingEngine.XLS ) ) {
   ((IRenderOption) renderOption ).setOption(
           IRenderOption.HTML_PAGINATION, Boolean.TRUE );
}
renderOption.setOption( IHTMLRenderOption.HTML_RTL_FLAG, new 
Boolean(false) );
renderOption.setOption( IHTMLRenderOption.MASTER_PAGE_CONTENT, new 
Boolean( true ) );
renderOption.setOutputStream(out);
renderOption.setOutputFormat(format);
task.setLocale(ULocale.forLocale(Constants.DEFAULT_LOCALE));
task.setRenderOption(renderOption);
task.render();
task.close();
reportDocument.close();

is there something im missing, and not settting to render options, while 
report viewer sets that something?

Thanks for any reply
