... catalog reindexing problem ... <dtml-call "_[userid].propertysheets[1].manage_changeProperties(REQUEST)"> <dtml-call reindex_object> ... did not work ...

The good news is that I have seemingly found a way to update my catalog by making a method of my zclass called update_dtml which I call when change the data of an instance. the method contains only one thing (of course):

<dtml-call reindex_object>

I call it from the dtml that manipulates the data of the instance (from a file in the same directory as the instances):

<dtml-call "_[userid].propertysheets[1].manage_changeProperties(REQUEST)"> <dtml-in "objectValues(['zclassuser'])"> <dtml-var update_dtml></dtml-in> ... does work ... Why?

I guess: <dtml-call "_[userid].propertysheets[1].manage_changeProperties(REQUEST)"> <dtml-in "objectValues(['zclassuser'])"> <dtml-var reindex_object></dtml-in> will work, too. In the case, that does not work, you call "reindex_object" for the object for which the DTML code was called (probably a folder). This is not the same as the object changed "_[userid]". Otherwise, you would have been able to omit this "_[userid]". In the working case, you call "reindex_object" for each of your class instances. This includes obviously the one that has been changed.
