[flexcoders] How to dynamically create the Object attribute names at run time?

[joseph_freemaker]

Want to create a new Object() and dynamically define the object
attribute names at run time.

This can be done statically using something such as the following:
var o : Object = new Object();
o.field1 = "abc";

In this case the input data fields are dynamic, so I want to assign
the 'field1' attribute name at run time.

Is this possible?

Thanks in advance.
