This framework is known to be troublesome. If possible avoid the usage. If you cannot avoid it, use this blog for know fixes.
Questions that will be answered are:
- Why avoid the use of the ACF framework?
- Which use cases can already avoid ACF framework?

Why to avoid the ACF framework?
The ACF framework relies on a separate installation file on the desktop of the end user. In the default scenario, this file is present on the SAP server and will be pushed to the end user when needed. But most of the desktop software settings on the users desktop will block this file for security reasons. This will force you to distribute these files via the desktop team. After a support pack or upgrade, the ACF file gets renewed and again you have to take care. The ACF framework also depends on the JAVA versions installed on the desktop and the browser.
The ACF framework is known to be delivering nasty issues which are hard to tackle and solve. Any software change on the desktop can lead to issues with the ACF framework.
Avoid the use if possible.
