Wai commented on OFBIZ-7754:
----------------------------

A property value can be empty.  It is the same as commenting out a property.  
In such a case, a default value in ofbiz code would be used.

"...But is it required? Please give me a number of examples where this is 
needed. As far as I can see a properties value always has content either Y/N or 
False/True or a value...."

    >>>A sample case in which an issue would result is if nothing is a valid 
value for a property.  In such a scenario, if the user wants to set the 
database-based version of the property to nothing, the code would proceed to 
get a value from the file-based counterpart. Which is not what is desired.

"...Further, anybody just starting with the system will try to change the most 
important properties file 'general.properties' and will see no result...."

    >>>It should be noted that the database-based version of property is a 
special case.  Generally, a user using ofbiz in single tenant mode would be 
using the file-based properties.  In such a situation, the user should not have 
loaded the database-base version into the database.
    >>>And if seed data for database-based properties need to be loaded, it 
should be customized according to the user's requirements.  In other words, 
those properties that are not required should be edited out before seeding.


> The big problem when load seed.

> Hi All,
> Regarding, [OFBIZ-7112|https://issues.apache.org/jira/browse/OFBIZ-7112]
> That's good for who start on use the ofbiz with initial setup, but not for 
> the site that already online and has to update the OFBiz core. Because when 
> has update OFBiz core they will use command load-seed for update.
> The problem is if we use load-seed mean the configuration data that's already 
> exists will be replaced by the data from this file,
> *CommonSystemPropertyData.xml*
> So, for my suggestion should change the reader from *seed* to *seed-initial*  
> or remove systemPropertyValue from the data file.
> Thank you,
> Kongrath
