Martijn Brinkers commented on TAPESTRY-2503:
--------------------------------------------
Workaround (found on mailinglist) is to create a ConditionalComment component.
Usage example:
<!-- IE requires a change to the error style -->
<t:ConditionalComment t:condition="IE">
<style>
HTML BODY DIV.t-error LI {
margin-left: 20px;
}
</style>
</t:ConditionalComment>
package mitm.mimesecure.web.components;
import org.apache.tapestry5.BindingConstants;
import org.apache.tapestry5.MarkupWriter;
import org.apache.tapestry5.annotations.AfterRender;
import org.apache.tapestry5.annotations.BeginRender;
import org.apache.tapestry5.annotations.Parameter;
public class ConditionalComment
{
@Parameter(required = true, defaultPrefix = BindingConstants.LITERAL)
private String condition;
@BeginRender
public void beginRender(MarkupWriter writer)
{
writer.writeRaw("<!--[if ");
writer.writeRaw(condition);
writer.writeRaw("]>\n");
}
@AfterRender
public void afterRender(MarkupWriter writer) {
writer.writeRaw("<![endif]-->");
}
}

> Project: Tapestry
> Issue Type: Bug
> Components: Framework
> Affects Versions: 5.0.13
> Reporter: Martijn Brinkers
> Assignee: Howard M. Lewis Ship
>
> I tried to add an Internet Explorer conditional style to solve some rendering
> differences between IE and FF. To way to add conditional comments is by using
> the following syntax
> <!--[if IE]>
> Special instructions for IE here
> <![endif]-->
> The problem is that Tapestry adds a space between <!-- and [if IE]
> example: <!--[if IE]> becomes <!-- [if IE]> (note the added space)
> IE only accepts the conditional comment if there is no space between <!-- and
> [if IE]
>
