Intermittent "error In Loading Data" Message

[boywithk9]

Since upgrading to 3.2, I get intermittent "error in loading data" messages for some charts. Since the problem only happens sometimes (about 50% of the time), it's not a question of the URL for the xml file being incorrect. The only unusual thing about my setup is that the xml files live on a different server from the php file. I'm using a relayer that you provided to accomplish that. (I don't have ftp rights on the main server, which is why I need to keep the xml files elsewhere.)

 

The second graph on the following page is most prone to this problem:

Any suggestions?

I was able to get the problem to occur while debugging mode was on, and I got the following error:

 

ERROR: An error occurred while loading data. Please check your dataURL, by clicking on the "dataURL invoked" link above, to see if it's returing valid XML data. Common causes for error are:

No URL Encoding provided for querystrings in dataURL. If your dataURL contains querystrings as parameters, you'll need to URL Encode the same. e.g., Data.asp?id=101&subId=242 should be Data%2Easp%3Fid%3D101%26subId%3D242

Different sub-domain of chart .swf and dataURL. Both need to be same owing to sandbox security.

Network error

 

It looks like something changed in 3.2 that is causing the use of the relayer to fail intermittently.

[boywithk9]

I changed my setup to not use the relayer, and the error is no longer occurring. So it looks like the relayer php you gave me no longer works with v3.2.

[Guest Basundhara Ghosal]

Hi,

 

As you have already stated, you need not require to specify the same explicitly from v3.2 onwards.

 

I hope this helps.
