hdcms Hi. Me again. Had a question, but I've already been able to answer it. A construction of {} is reserved for plugins, and as I just confirmed this custom fields are being placed by a plugin designed for it. Problem is that this plugin is meant to work with content component and not in places like 3rd party component or modules. Right now it's threated as any other plugin and is not parsed, but can also be set to be removed from showing.
I'm not saying that our developers may come with a solution to that, but it basically means that we need to develop a new plugin working with our component only.
