Is Richfaces.ComboBox.setInputWidth() buggy?

[pjmlp]

Hi,

this question relates to a previous one that I have posted, but it a bit difference, hence the new post.

I am trying to redefine some of the comboBox CSS classes, but without sucess. Regardless of what I do, I always end up getting one pixel less in the comboBox, as you can see on the image.

Looking at the setInputWidth() code, I see the following:

 setInputWidth : function() {
    var width;
 if (Richfaces.browser.isIE6) {
 width = parseInt(this.field.parentNode.style.width) - this.BUTTON_WIDTH;
 } else {
    width = parseInt(this.field.parentNode.style.width)
          - parseInt(Element.getStyle(this.field, Richfaces.borders.l))
          - parseInt(Element.getStyle(this.field, Richfaces.paddings.l))
          - parseInt(Element.getStyle(this.field, Richfaces.paddings.r))
          - parseInt(Element.getStyle(this.field, Richfaces.borders.r));
    width -= this.buttonBG.offsetWidth ? this.buttonBG.offsetWidth : this.BUTTON_WIDTH;
 }
 this.field.style.width = width + "px";
} 

The values for  Richfaces.borders.l, Richfaces.borders.r and  Richfaces.paddings.r is 0, only Richfaces.paddings.l is 1.

Now the calculation above ends up removing a pixel on the right on the comboBox input field, as shown on the image above.

Is the function buggy or am I doing something wrong?

Thanks in advance,
Paulo
