Subject [jira] [Commented] (TRINIDAD-2071) Connection Failed
Date Fri, 25 Mar 2011 21:02:05 GMT


Scott O'Bryan commented on TRINIDAD-2071:

I guess the larger question here is why is the connection failing?  I'm not sure simply commenting
out the feedback is an appropriate suggestion, especially since it causes a delay.  Without
the message you would have no idea why your app was failing.

>                 URL:
>             Project: MyFaces Trinidad
>          Issue Type: Bug
>          Components: Components
>    Affects Versions: 1.0.5-core
>         Environment: We are running on a Unix server using Oracle 10g as an application
server in a clustered environment
>            Reporter: ACTUR
> We are experiencing a connection failure  issue the message appears to be coming from
trinidad-impl-1.0.5.jar - \META-INF\adf\jsLibs\xhr\RequestQueue.js stating a connection failure.
This usually happens when a user selects a component that is doing a partial page refresh.
The application hangs for about 20 seconds and then returns the connection fail message. We
only found one similar issue out there and with a work around to comment out the message in
the RequestQueue.js however this does not completely fix the problem we still experience the
delay without the message. Is there a fix for this.  Below is the solution we have found on
a blog: 
> TrRequestQueue._alertError = function()
> {
> 	 var failedConnectionText = TrRequestQueue._getFailedConnectionText();
> 	if (failedConnectionText != null)
>     	alert("Trapped Connection Failed !!! ");
> }
> TrRequestQueue._getFailedConnectionText() : This method returns 'Connection
> Failed' This message is given whenever any issue occures with IFrames that
> are used internally in trinidad. But it has no major impact on app, so can
> be taken as warning. SO the solution is to just override this method &
> comment out the code as below.
> TrRequestQueue._alertError = function()
> {
> 	// Do nothing. Supressing alert code.
> 	// var failedConnectionText = TrRequestQueue._getFailedConnectionText();
> 	 //if (failedConnectionText != null)
>     	//	alert("Trapped Connection Failed !!! ");
> }
