[OpenLayers-Users] Mobile Support: Handling a tap like a mouse click... (fixed)

[Leonhard Dietze]

Hi everybody,

in case somebody else stumbles over this message. After a lot
of OpenLayers/Javascript/Jquery-Debugging I finally found
the problem with my code (with JQuery,OpenLayers,JQuery-UI):
I was trying to stop the Click-Event from being further
evaluated. When I finally removed the line
    "Event.stop(oEvt);"
all the errors dissapeared.

This was the exception I received a lot of times in Firebug:
   uncaught exception: [Exception... "Illegal operation on WrappedNative
   prototype object" nsresult: "0x8057000c
   (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame ::
   http://localhost/js/OpenLayers-2.11rc.js :: anonymous :: line 252"
   data: no]

So everything now works fine with the source given in my last
mail as it was described by Chris Schmidt and Steve Lime.

And: Thank you very much Steve and Chris for your running examples,
it helped me a lot to know that it should/will actually run with
this setup on the iPAD.
