Safari Issue

[GinnTech]

I have a site that works perfectly in IE6 IE7 FF2 FF3 but not in the
latest Safari.

Here is the issue. I am attempting to call functions within a flash
object. When trying to attempt to retrieve the object to call the
functions IE6 IE7 FF2 FF3 all return Objects to work with. In Safari
a function is returned. Here is the code.

The code errors at

with

object.

Low and behold it's not an object it's a function in the eyes of
safari.

Does anyone know a work around for this in safari.

Thank you,

// local variable definitions

How can these be local variable definitions when they are in fact *global*
variable *declarations*?

var apiHandle = null;
var API = null;

This variable is never read.

var findAPITries = 0;

[...]
function initAPI()
{
var api = getAPIHandle();

A local variable named `api' is declared and initialized here.

if (api == null)
{
alert("Unable to locate the RTE's API Implementation");
return "false";
}
else
{

Since execution continues in this branch, getAPIHandle() would return a
value that is not equal to `null' after type conversion.

api.setActivityID( document.forms[0].activityID.value );

Since an error occurs when calling the method, getAPIHandle() would return a
value that is either not an object reference (but not equal to `null' after
type conversion) or the object referred to would not have such a method.

return null;
}

win = win.parent;

}
//ToDo:Start Here Debugging how to get Safari to see this object.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^

return win.API_1484_11;
}

As everything boils down to this method, the problem that causes the error
in the first place is to be found in there. But ISTM debugging needs to be
started on top of it.

[...]
function getAPI()
{
var theAPI = findAPI(window);
if ((theAPI == null) && (window.opener != null) &&
(typeof(window.opener) != "undefined"))
{
theAPI = findAPI(window.opener);
}
if (theAPI == null)
{
alert("RTE - Can not locate API adapter");
}
return theAPI
}

Utter nonsense. Safari very clearly says that the result of
api.setActivityID, which is the `undefined' value is not an
object (and so also no Function object).

Does anyone know a work around for this in safari.

if (api)

instead of

if (api == null)

might suffice to avoid the runtime error.

Nevertheless, the code would still have several other issues.

You don't show how you call the code, calling getAPI from window.onload
gives "RTE - Can not locate API adapter"

with
Value undefined(result of expression api.setActivityID) is not
object.

Low and behold it's not an object it's a function in the eyes of
safari.

The code you posted doesn't do that for me. Perhaps you should post a
link to a minimal example that shows the error.
