Hi Gustaf,
Note that you need as well the newest code from OpenACS from the oacs-5-10 branch. Let me know, how this works out for you.
Do I need to download it directly from CVS somehow. I am unsure how to download the latest oacs 5.10 from CVS.
I went to https://openacs.org/projects/openacs/download/ and downloaded the openacs 5.10 and 5.10 beta tar files but it does not look like the change you were talking about were there.
parameter::* interface should be now cluster proof (added acs::clusterwide for clearning and callbacks)
I was expecting to see an acs::clusterwide inside the ad_parameter_cache proc. Where exactly did you make your changes?.
Marty.
