Java / Batik, modifing attribute in java, updating SVG DOM -

-

i have redendered svg document several symbols. in java application modify attribute in dom changing stop-color attribute using setattributens.

i can see attribute modified , changes new value, svg document render not reflect change.

if same in browser using javascript, dom updates , change visible. there need batik render reflect changes in dom?

edit: in addition being able modify attributes in java , see updates. have seen other behaviour works in browser same svg file doesn't in java application. example using browser dom debugger, can modify stop-color attribute of lineargradient , see change in browser, using script or java in batik application doesn't work, no change seen.

edit2: have found if change fill attribute of element using lineargradient, modify stop-color attribute of linergradient, change fill attribute lineargradient works, not if leave fill attribute unmodified. behaviour in batik.
