Problems with setProperty, getPropertyValue() and adding Attributes

[Rufus Buschart <Ru...@rtc.bosch.com>]

Hello,

i tried to view the example from 
http://www.xml.com/pub/a/2002/09/11/quint.html in Squiggle. This example 
displays without any problem in the Adobe SVG-Viewer. But when I tried 
to view it in Squiggle, I found three major problems:

First problem (not very serious):
In line 151 and others: tspan.style.setProperty('word-spacing', space + 
'px'); Doesn't work. I had to change it into: 
tspan.style.setProperty('word-spacing', space + 'px', ""); Is this a bug 
in Rhino or is the ECMAScript Implementation by Adobe more sleazy?

Second problem (very serious):
The method style.getPropertyValue() (line 71ff) is not working always 
correctly. It works for:

this.setFontFamily( style.getPropertyValue('font-family') );
this.setFontSize( style.getPropertyValue('font-size') );
this.setTextRendering( style.getPropertyValue('text-rendering') );

but not for

style.getPropertyValue(''text-align') );
style.getPropertyValue(''line-interval') );

Whats this??

Third problem:
I can't add the same attribute twice to a element (lines 203 and 215). 
This is probably a bug in Rhino, because i do think, that the second 
attribute should overwrite the first.

Thanks,

Rufus

    The CSS DOM specifies three parameters for this method.  Some have
argued that in EcmaScript you should accept only two treating the
third as "", make your own decision who is wrong - but Batik requires
three parameters.

   I don't see 'text-align' or 'line-interval' as properties in the
SVG specification ;)

   Seriously I don't think this is good coding practice there is _lots_
of missing information for these unknown properties.  What is there type,
what is there default value, are they inheritable, what is the computed
value (for example '1.5em' is typically not a computed value - so these
are not Idle concerns).

   It does it's just that the first time this is called this._y
is 'null' so your transform becomes "translate(10 )"  which is not a
valid transform.
