spans leaving behind extra whitespace after page generation

[Josh Joy <jo...@yahoo.com>]

Hi,

I generate a lot of dynamic content using @If and
@Else and @For within 
span tags. Within these span tags is the actual
content that becomes 
generated. This works, no issues so far. My only
concern, is that these 
span tags containing the jwcid with the various tags
leave behind empty 
lines, whitespace. While they obviously generate the
content, tapestry 
is not removing this whitespace perse. When used in
conjuction with img 
tags, the extra whitespace does become an issue on
browsers as they will 
actually translate the whitespace between my img tags
as intended 
whitespace rather than ignore them, thus introducing
unwanted spacing 
between my images.
My question is, for my span tags with jwcid
atttributes, after Tapestry 
processses these can I somehow ask it to remove the
tag and the 
whitespace, rather than just removing the tag and
leaving behind 
whitespace in it's place?

I'm using tapestry 4.0.2

Thanks,
Josh

Re: spans leaving behind extra whitespace after page generation

Tapestry 4 doesn't have any real knowledge of the content of your
page. It leaves a lot of excess whitespace in place because it can't
tell if it is significant (and if you use, say <pre>, it might be).

I tend to put extra whitespace INSIDE the tags, i.e.:

<span jwcid="@If" ...

>Something</span
><span jwcid="@Else"
>Alternative</span
>

Looks ugly, but works. Also <span jwcid="$remove$"> is useful.
