[Vtigercrm-developers] VTiger Extension Module create custom field for Invoice Module

[Tim Mohrbach]

I would have done it the same way, remember to increase the version number of the extension in the schema xml file… sry mate I am bad help…

I have always wondered about this: does it try to create a new field everytime it updates the extension or is the addField method tolerant enough to ingore the field in case it’s already there?
