We have now built a test plugin and simple test pages to reproduce and isolate the bugs:

- testPlugin.html is the page that embed the plugin itself. It has three buttons 
   - one to call a method StartPlugin()
   - one to set a property DialDomain
   - one to read the property and display the value in an alert box.

- testPlugin1frame.html: this page includes the former page inside an IFRAME. It has also three buttons
  - one to call the mthod StartPlugin by calling a JS function defined inside the child IFRAME
  - one to call the method StartPlugin by calling it directly from inside the page
  - one method to set the DialDomain property by calling a JS function defined inside the child IFRAME

- testPlugin2frame.html the page includes testPlugin1frame.html insde an IFRAME to create a second level of IFRAME embedding.

TestPlugin.zip is the source code of the test plugin. YOu'll have to compile it with XCode and copy the plugin directory into /USers/yourusername/Library/Internet-Plugins to activate it. It sends traces to the system console messages

Here are the situation where the plugin work

1/ load testPlugin.html in Webkit browser

- call StartPlugin(): method called ok. argument ok, callback is raised corrrectly
- set property: ok. data received correctly
- read propery: ok

2/ load testPlugin1frame.html in Webkit browser

- call StartPlugin() from inside the IFRAME: method called ok. argument ok, callback is raised corrrectly
- set property from inside the IFRAME: ok. data received correctly
- read propery from inside the IFRAME : ok

- call StartPlugin from parent page using function defined in child: ok
- call StartPlugin from parent page acessing plugin directly from paren: ok
- call set property from parent page using function defined in child: ok

Now Here is how to reproduce the bugs

LOAD testPlugin2frame.html

- call StartPlugin from parent page using function defined in child: NOK. Data received is NULL and callback is not executed 

- call StartPlugin from parent page acessing plugin directly from parent: Data received is NULL and callback is not executed 

- call set property from parent page using function defined in child: NOT data received is null.

Please advise
