Multiple times I have had the same component number/id on a popup modal as a component on the background page. When using Javascript and TB.render I end up doing things to the component on the background page that I do not want to do because it has the same component id as the component I am trying to affect in the popup modal.
If component ID’s are never repeated this would not be an issue.
@christopher93 Thanks for sharing, that is a good idea for a workaround. I resolved my issue by recreating one of the components to force it to get a new / unique number.
