Provider needs to hide or show some mandatory attribute from Account Creation wizard. For example attribute is "Zip code". In PCP/RCP Account creation wizard uses the following XMLs for Personal or Company Account types:
# ll Account_Add*
-rwxr-xr-x 1 pba apache 138 Jun 21 15:28 Account_AddCustomerCompWin.xml
-rwxr-xr-x 1 pba apache 138 Jun 21 15:28 Account_AddCustomerPersWin.xml
Zip code element is described in the following sections:
Zip / Postal Code
To hide this element one may create (or edit existing) customization file in the "customization" subfolder"
And add the following text there:
<grid id="dataCompany Postal Address" group="Company Postal Address">
<row id="Zip" remove="yes">
Thus only a single element visibility will be customized.
WWW service restart is required after that:
