Subject [jira] Commented: (COCOON-1918) unwanted whitespace or "block" characters in browser tooltips/help bubbles
Date Thu, 21 Sep 2006 16:34:23 GMT
    [ http://issues.apache.org/jira/browse/COCOON-1918?page=comments#action_12436575 ] 
            
Guillaume Déflache commented on COCOON-1918:
--------------------------------------------

Solution #1 : replace in default styling's XSLT stylesheets all "fd:hint" XPath expressions
used for "title" attributes by "normalize-space(fd:hint)":
 - this will not solve the problem for other (custom) stylings
 - this only cares for "fd:hint", but similar problems can occur with other "display-data"
elements : "fd:label" and "fd:help"

Solution #2 : remove this ignorable whitespace when the form definition files are read, by
removing the first and last whitespace-only DOM text nodes if they exist:
 - the current implementation requires that a read-write DOM document is used in the widget
definition builder to work, I could not check if or where it is guaranteed

>          Issue Type: Bug
>          Components: Blocks: Forms
>    Affects Versions: 2.1.8, 2.2-dev (Current SVN), 2.1.9, 2.1.10-dev (current SVN)

> Problem : almost all tooltips contain extra characters around the text provided in the
"fd:hint" element : with IE, they are always rendered as whitespace, with Firefox, some (tabs
IIRC) appear as "block" characters.
> These originate from the whitespace used for formatting the form definition files.
