No registered function factory for any user-defined functions or magic properties - occasionally

[Jack Hodges]

Occasionally TBC will get itself into a mode where it suddenly refuses to acknowledge any of my SPIN functions or magic properties. It is infrequent enough that I forget the recipe to fix it, opting for ever increasingly drastic actions (starting with refreshing the registries, and sometimes restarting TBC). I just did all of these with no affect, so I closed all tabs and reopened them and suddenly everything was working again. Is there a button I can select that will unwedge any internal inconsistencies or must I just remember to close and reopen all graphs? I am reluctant to do this because I may have 10+ SPARQL tabs open with various things I am working on and I will lose all of them if I close all graphs. Is that the problem?

Hi Jack,

as you say it is hard to narrow down something on vague scenario descriptions. I assume you are defining all your SPIN functions in .spin. files? I am asking because otherwise the visibility of functions depends on whether they are part of the currently active file (and its owl:imports) in TBC. And that may explain the rather random behavior that you are seeing.

In general, the menu item System > Refresh TopBraid System registries should do the reset without a need to close windows.

Hello Holger,

I only name SPIN files with .spin.ttl now for quite some time, and these graphs are definitely imported by the vocabulary I am testing on as they were working just fine until they stopped working. In fact, I have 3 graphs open, the vocabulary, the spin file and the magic properties file. And, as I mentioned, many SPARQL tabs. The same thing happened to me last night after posting this question. Closing all the graphs fixed the problem and I only had 4 or 5 SPARQL tabs open at the time so it wasn't quite so painful.

Hmm, sorry I have no other suggestion at this stage. Would need to "see"
it myself.
