Hey Ravi,
man that's true that you will not get compile time error, but rather
you will get Run Time Error.
I am sure, when we say error, it includes both compile time and rum
time errors. :)
also, not sure why you are saying data is already arraycollection.
When it is getting retrived using httpservice, it is an object unless
and untill you define the "resultFormat" and to use that data as a
Arraycollectin source, you do need to parse that object into
arraycollection.
I see only this xml which KKH's is using.
Xml:
<?xml version="1.0" encoding="utf-8"?>
<img>
<src>
<path>assets/1.png</path>
</src>
<src>
<path>assets/2.png</path>
</src>
<src>
<path>assets/3.png</path>
</src>
</img>
I am sure, whatever I suggested is correct in all respect. Please
correct me if I am wrong. :)
-HTH
Thanks,
Shaleen Jain
