Hi Using v0.33

I am send the xml from grid to server and all is ok if all columns in the grid has data, if some column in the grid is null (never I set a value) the xml send to server is bad form

for instance I get in the server and in Post tab of firebug it:
<?xml version="1.0"?>
<PostalCode/> ===========> PostalCode is null


var xmlAddress = dmAddress.getDocument();

when I watch the xmlAddress the xml is bad form from visual studio or firebug is it a bug in the datamodel? any solution?

kind regards
