Re: Max # columns in a custom list portlet definition?
Though there is no limitation on the number of portlet columns, we have a limitation on the length of the select clause while creating a datasource which is used by a portlet. The length of the select clause is limited to 4000 characters. Since the length of the select clause is limited, the column numbers should not be too large though it is not an exact number.
Best regards, Randall
