some URL`s like http://www.flexgrocer.com/categorySalesData.xml are erroneous

[BabyPowder]

I tried to get through the Flex 3 Trainingbook, I am now at unit 19
but I can`t see any charts.....when I try to lookup the HTTPService
links which should fill the charts with data I get xml error and my
charts are empty I just can see the text "Flex Data Vizualisation
Trial" that`s it

can anybody help or has the same Problem?

What makes you believe the URL is erroneous instead of an error
elsewhere in the entered code?

I took the URL you mention in the title, put it into a web browser and
it opens immediately. Doesn't seem to be a problem there.

http://www.flexgrocer.com/categorySalesData.xml (for reference)

If you are using Chrome or Safari, you may need to view source to see
the XML, but that is a factor of the browser, not the data.

Thank you for the quick response first

Sorry the Link I posted was wrong, that one is working and is ok like
you said but how about these ones:

http://www.flexgrocer.com/rawSalesData.xml

http://www.flexgrocer.com/salesData.xml

When I run Dashboard.xml I can`t see any data

When I copy and paste those links into a web browser, I receive XML.

I am guessing the bug you are looking for is elsewehre

[BabyPowder]

I am receiving this message when I try to lookup the two links

XML processing error: XML or text declaration not at start of entity
Address: http://www.flexgrocer.com/rawSalesData.xml
Line 2, column 1: <xml version = "1.0" encoding = "utf-8"?
^

When I try the files from the CD of the Book I have the same issue so
I can`t find any bug on my side

[Michael Labriola]

What browser are you using/ I will try to replicate it for you on this
side.

May can post me the XML that you can see, so I can copy and paste them
to a local XML file and can give a try what happens

Okay, I got it!

the failure is in Firefox.......it`s showed me other XML sides without
any problems.....
when I open the two links with the IE I can see the XML.....so why I
can`t see any charts?

Like I said I used as well the files from the CD and just can see the
text "Flex Data Visualization Trial" in the windows/boxes with the
scales.
When I click the DATA button it is empty

[Michael Labriola]

Because the xml is a red herring that you have become focused upon. I
guarantee there is some other small mistake that is causing the
problem. Have you compared your files against the known good files for
the end of the lesson on your cd?

If you would like to post your code, I am happy to take a look too

I copied the good files from the CD and same problem

[Michael Labriola]

You mention in your post this is lesson 19, but your code isn't close
to the code for 19,18 or even 17. It looks like the code for 16 with
some minor changes. Could you please confirm the lesson you are
working with?

Also, are you working with an English copy or a translation, I just
want to make sure there wasn't a change in lesson numbering. Compared
to my 18, your code is still using HTTPService and not Webservices,
which is a big change.

In addition to that, if I run your Application.mxml file and set a
break point at each of the result methods, I receive data back with
your code.

Finally, I loaded the completed code for 16 and 17 and ran it
successfully on my machine in all browsers. In Lesson 18, you are
instructed to begin modifying this code to work off your local
machine, and no longer from flexgrocer.com. This again points to the
fact that either your code is not from 19, or you have missed a few
lessons worth of steps.

I am glad to help you, but the information being provided at this
point is not consistent and I need to understand where we are mis-
communicating.

Mike
