I am able to create custom perl module in /iw-perl/site/lib to be used in tpl. However, I am not sure how I can make use of the submodules defined in TeamSite:T::iw_perl within the custom perl module.In my custom perl module, do I include module name like followings?use TeamSiteT::iw_perl qw(iwpt_dcr_value);In my subrountines within my custom module, can I simply call iwpt_dcr_value() like followings:sub isPeriodSpecified{ my $node = shift; my $startDate = iwpt_dcr_value('node.start'); my $endDate = iwpt_dcr_value('node.end'); if ($startDate ne "" && $endDate ne "") { return 1; } return 0;}I am getting Preview And Generate Error... I tried calling TeamSite:T::iw_perl::iwpt_dcr_value(), but it also not working.Anyone know how to use TeamSite:T::iw_perl within a custom module?
