This is why I'm not too excited about some of these solutions. Seems like I've been here, done that several times in my career: CMS software like Wordpress and Joomla, "Portals", repository and workflow solutions like Alfresco and Appian, etc.
They all save tons of time for a small prototype or very basic use cases, but the minute users want some special feature, you'll spend hours, days or longer fighting against the tool, driving yourself nuts because you know you could implement it in 30 minutes in a custom app. Or you're forced to become an "expert" in these tools, which turns out to be a really bad career move as years of experience with a specific framework will instantly become worthless as industry moves on to the next Big Thing.
