In the past we had a problem with dynamic content that would sporadically disappear from view on pages. From what we gathered, this didn't seem tied to any specific time or event and it would just disappear all of a sudden. And republishing the page would make it visible again. At that time we didn't have time to investigate this further and desided to stop using it instead (might have been before we upgraded to 6 R2 from 6).
We are now at a point where we are looking to rebuild the site and have decided that dynamic content will play a larger role in how we create out content. From rumors, we later heard that the problem with disappearing content was related to a bug in CMS 6/6R2. Was this the case and if so, have it been fixed in later patches? We are also waying in the desition to upgrade to CMS 7.5. Have the fetures with dynamic content been improved in 7.5?
Dynamic Content seems to be the same in 6 and 7. But I guess most people use blocks instead of Dynamic Content in EPi 7, you can even drag blocks into TinyMCE.
We've used DC for a few things in 7 and haven't had any problems though.
