Batik Script issue

[Sachin Gupta <sa...@gmail.com>]

Hi,

I am using batik in my application. I am trying to set hidden object in HTML
form using  javascript.
e.g. myform.inputtext.value=myarr

As batik uses rhinoscript i am using liveconnect functionality to interpret
javascript.

I tried using JSObject.setMember in put method and getting following
exception.

netscape.javascript.JSException: Parameter not optional.

org.apache.batik.script.InterpreterException: Parameter not optional.

org.apache.batik.script.rhino.RhinoInterpreter.evaluate(RhinoInterpreter.java:288)
    at
org.apache.batik.bridge.BaseScriptingEnvironment.loadScripts(BaseScriptingEnvironment.java:513)
    at
org.apache.batik.bridge.UpdateManager.dispatchSVGLoadEvent(UpdateManager.java:238)
    at
org.apache.batik.bridge.UpdateManager.dispatchSVGLoadEvent(UpdateManager.java:220)
    at
org.apache.batik.swing.svg.SVGLoadEventDispatcher.run(SVGLoadEventDispatcher.java:100)


and if i use eval method then there is no exception but the values are not
set in my form object.

Regards,
Sachin

Hi Sachin,

Note that this is somehow unrelated to Batik (this a general Java
applet and HTML<-->applet communication question) and therefore should
probably be crawled/asked somewhere else (Rhino mailing list, maybe?).
Nevertheless, I recall a few threads which lightly touched this
subject so you may find a few answers within this mailing list
archives also.

Without a proper context (in this case, probably a code snippet) it's
very hard to provide any interesting feedback. Please consider
providing one if you follow-up on this thread or if you redirect this
into a more specific mailing list. Also, environmental information
(operating system, java version, etc., software version) also usually
help. ;-)

Again, guessing on what's happening is very difficult. :-|  I'd invite
you to get a bit more familiar with effective bug reporting [1],
(specially regarding reproducibility [2] [3]) and test case reduction
[4]. :-)  (It would be valuable, as stated above, if you decide to
rewrite a polished version of this question to redirect into another
forum or follow up with more information.)

Hope this helps,
