Hello
I'm having problems when I create some direct method of JavaScript, it always tells me that I can not get ownership of any library that I'm sending to call.
I leave the legend of the error and my code, hoping you can support me.
Technical Message: Event handler failed with message: No se puede obtener la propiedad 'relTabbar' de referencia nula o sin definir
Stack Trace: Client Side Error
var tabbar = parent.relationships.relTabbar;
var tabTelecom = tabbar.GetTabId("Certificado Gral");
var tabGral = tabbar.GetTabId("Certificado IFT");
tabbar.setTabVisible(tabTelecom, true);
tabbar.setTabVisible(tabGral, false);
with this code what I try is to hide one or another tab of relationship, take the example of the development guide.
Thank you
