write to meter with attribute Index=0

Hi. when we want to write object all attribute on meter (like clock object)
I pass index =0 to below function :
public void Write(GXDLMSObject obj, int index)
{
//it is as is in GXDLMSCommunicator class
}

in this method the order of writing attributes are sequential and start from 1 and goes on to attribute count and if the attribute is dirty writing done.

but there is problem for object like "Clock". because when I want to write attribute "begin" , if attribute "enabled" odes not written first, the meter returns error.

do you have any Idea that we can have this one method for all object writing with dirty indexes ?
