Bug 321144

Description Jason Weathersby 2010-07-28 11:48:12 EDT

If you add the agentstyle parameter to the viewer url and set its value to false:
__agentstyle=false

This throws a null pointer exception.  This creates a proplem for API users as this is the default value for agentstyle.  To work around the issue users need to add the setEnableAgentStyle(true) command to there code.

		HTMLRenderOption options = new HTMLRenderOption();		
		options.setOutputFileName("output/resample/MySQL.html");
		options.setOutputFormat("HTML");
		//options.setHtmlRtLFlag(false);
		options.setEnableAgentStyleEngine(true);


The error happens in

HTMLVisionOptimize.java (getElementStyle returns a null)

	public void buildCellStyle( ICellContent cell, StringBuffer styleBuffer,
			boolean isHead, boolean fixedCellHeight )
	{
		IStyle style = getElementStyle( cell );
		// implement the cell's clip.
		if ( fixedReport )
		{
			HTMLEmitterUtil.buildOverflowStyle( styleBuffer, style, true );
		}
The null style is then passed to the buildOverflowStyle method and 

	public static void buildOverflowStyle( StringBuffer buf, IStyle style,
			boolean outputHidden )
	{
		String overflow = style.getOverflow( );
throws the exception,
