I am trying to update a Woodstock 4.2M1 table using Dynafaces transactions,
but I get a Javascript error using Internet Explorer 6 and 7.
The error says "'null' is null or not an object" and it happens on
re-rendering of the table (I know this because debugging my app I see that
the prerender() method is correctly hit).
When debugging the javascript, error happens in prototype.js file in this
code snippet:
respondToReadyState: function(readyState) {
var event = Ajax.Request.Events[readyState];
var transport = this.transport, json = this.evalJSON();
if (event == 'Complete') {
try {
(this.options['on' + this.transport.status]
|| this.options['on' + (this.responseIsSuccess() ? 'Success' :
'Failure')]
|| Prototype.emptyFunction)(transport, json);
} catch (e) {
this.dispatchException(e);
}
if ((this.header('Content-type') || '').match(/^text\/javascript/i))
this.evalResponse();
}
try {
(this.options['on' + event] || Prototype.emptyFunction)(transport,
json);
Ajax.Responders.dispatch('on' + event, this, transport, json);
} catch (e) {
this.dispatchException(e);
}
/* Avoid memory leak in MSIE: clean up the oncomplete event handler */
if (event == 'Complete')
this.transport.onreadystatechange = Prototype.emptyFunction;
},
dispatchException: function(exception) {
(this.options.onException || Prototype.emptyFunction)(this, exception);
Ajax.Responders.dispatch('onException', this, exception);
}
});
actually the "json" variable is "undefined" because the call to
this.evalJSON() returns nothing.
Everything is working perfectly using Firefox.
Any ideas or hints about a possible workaround?
thanks
Mauro
