For Example value of an integer field named 'Alignment' needs to update to blank value from for a integer value.
if the alignment is set alignment = "" as follows :
<Project projectID="14" name="Kovair Project 1mn Mod" alignment="">
Following error is thrown :
attribute "alignment" has a bad value: "" does not satisfy the "integer" type
if the alignment is not included as follows :
<Project projectID="14" name="Kovair Project 1mn Mod">
the attribute is ignored and not getting updated.
Is there any extra attribute to be added in the post xml, to achieve the same?
