Custom component names invisible in SOPC Builder 8.0sp1

I had the problem for two different projects. I reported the problem to Altera.

For one of the projects, the custom components were in a subdirectory called something other than "ip". To tell SOPC Builder where to find the components, I ran "Tools --> Options", selected IP Search Path, clicked "Add", and added the name of directory containing the components. The component names would no longer be listed by their bullet dots when I reopened the SOPC Builder system. The names would be back if I deleted ip_cache and altera_ip.ini at "C:\Documents and Settings\$USERNAME\.altera.quartus", readded the IP search path, and ran "File --> Refresh Component List". I still had a problem with the custom components already added to the system being displayed correctly. I didn't find a complete workaround. I didn't try regenerating the components in 8.0, so I don't know whether that would fix the problem for this project.

For the other project, the custom components were in a subdirectory called "ip". In this case, the text of the component names was missing for some of the components that didn't have "set_module_property "displayName"" in the *_hw.tcl files. I fixed the problem by adding that module property manually, but Ketan's suggestion to regenerate the component in 8.0 should also work.
