ConvertEmptyToNull
boolean ConvertEmptyToNull;
Description
determines if an empty text should be treated as a NULL value.

When the user enters text into a pattern field, and after this, the control content is to be committed into the database field the control is bound to, a decision must be made how to deal with empty strings.
This is controlled by this property.

If the property is set to true, and an empty text is to be commited, this is converted into NULL, else it is written as empty string.

Apache OpenOffice is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
