In our project in the main site, we have the following for adding css for IE6 and IE7 to the page inside the <head> tag.
<!--[if lte IE 7]>
<link href='index_ie7.css' rel='stylesheet' type='text/css' />
<!--[if lte IE 6]>
<link href='index_ie6.css' rel='stylesheet' type='text/css' />
This worked fine until version 1.6.0 ... but now when using ICEfaces 1.7.0-DR1 after partial submits of the page the head is reloaded and all links (and so the CSS styles) are gone. This also happens with an empty <f:verbatim> tag. Is this already a known problem with 1.7.0-DR1 or is there another workaround for including conditional comments and so different CSS-files for the different IE-versions?
