Save Last Value on on Form Form

Use pack/unpack on Form

If you have used runbase classes, you may be impressed by its pack and unpack mechanism. It allows users to keep the input values of last time. If you want to implement the same mechanism on the Form, it is easy as well:
Besides Pack/Unpack, add these six methods:
public dataAreaId lastValueDataAreaId()
{
return curExt();
}

private UserId lastValueUserId()
{
return curuserid();
}

private UtilElementType lastValueType()
{
return UtilElementType::Form;
}

private IdentifierName lastValueElementName()
{
return this.name();
}

private IdentifierName lastValueDesignName()
{
return ;
}

//this is called when no last value is retrieved
void initParmDefault()
{
}

further, in Close method of the form:
public void close()
{
super();
//add saveLast method after super()
xSysLastValue::saveLast(this);
}

in init method of the form:
public void init()
{
;

    //Add getLast method before super()
xSysLastValue::getLast(this);
super();

}
