Remove for single value attributes

This may be a dumb questions, but I am looking for an equivelent to the IDfTypedObject.removeAll(attribute_name) for a single value attribute. Both remove and removeAll only seem to work on multi-value attributes.

As I perform this function, I will be looping through a list of attributes that could be of different types, so I'm trying to avoid something like a setString where I would need to know the type of the attribute.

Try setNull(attribute_name)

I've tried that already. It doesn't seem to do anything. The documentation says it's "reserved for future use".

What about setValue(attribute_name,null)?

Girevik

I tried that as well. It throws an error (I'd have to dig it out to find which one).

I appreciate the suggestions, though!

I think you will need determine attribute type in order to null it out.

Unfortunately I think so too. I can't beleive they don't provide a way to do that on single value attributes.

Thank for your help.

For single attribute, Content Server doesn't support real null value. It has a default one stored in DB. Since D6.6, Content Server support SPACEOPTIMIZE for default values. Please refer to DQL reference, section "NULLs, default values, and DQL".

NULLs, default values, and DQLIn releases before release 6.6, Documentum did not allow you to assign NULLs as a property value because NULLs are used to terminate the lists of values in repeating properties. In 6.6, support for assigning NULLs as a property value was added. If you specify the SPACEOPTIMIZE keyword when creating or modifying a property, NULL values can be assigned to that property.
