JSR 226 RI setTraintNS() bug?

[jessicay]

Was checking out JSR 226 SVGT RI. Trying with Nokia prototype SDK.

<circle id="circle" cx="15" cy="15" r="10" fill="yellow"/>
</defs>
<use id="displayshape" xlink:href="#rect"/>
</svg>

My MIDlet just trying to change the displayshape to circle instead. use the following code,

//get Document first
SVGElement shape = (SVGElement)(doc.getElementById("displayshape"));
shape.setFloatTrait("x", 30);
shape.setFloatTrait("y", 30);
shape.setTraitNS("http://www.w3.org/1999/xlink", "href", "#circle");
System.out.println("new href is"+shape.getTraitNS("http://www.w3.org/1999/xlink", "xlink:href"));

the element shown on screen does change the coordinates accordingly but not the shape, though the print out info for "new href" is "#circle". It does not matter if I use "xlink:href" instead of "href".

Counldn't find anything wrong. Anybody got ideas?

Thanks,

*Sigh* .. 1.5 years later and this bug stilll seems not to be fixed. I try to change the "xlink:href" attribute in a <use> tag by invoking:

m_CurrentElement.setTraitNS("http://www.w3.org/1999/xlink", "href", "#Entry3");

But it doesn't work. Any hints? And btw: Is the JSR 226 implementation on a real NOKIA Phone broken as well?

Hi,

Are there any news on this bug?

I see you wrote this in September 2003 .

Not exactly a timely reply then ....

I had a similar problem when I declared the elements I wanted to reuse in a defs element. This worked OK on the Sun emulator but not the Nokia S60 emulators. I believe lack of support for the defs element in SVG Tiny is the culprit. If I put the element I wanted to reuse in a g element instead which is supported by SVG Tiny 1.1 it worked Ok on the Nokia S60 emulators.


eg

SVGElement g = (SVGElement) doc.createElementNS(root.getNamespaceURI(), "g");
g.setId("example");

//Add elements for reuse as children to group g element.

...

root.appendChild(g);

//Starting reusing group
SVGElement use = (SVGElement) doc.createElementNS(root.getNamespaceURI(), "use");
use.setTraitNS("http://www.w3.org/1999/xlink",
"href",
"#example");
use.setFloatTrait("x", x1);
use.setFloatTrait("y", y1);
root.appendChild(use);
