Question

Hello,

I want to set up a user group, where the list of members is easily maintainable via a nice form added to the topic of the group. The form works fine, and the group shows the correct content on views, but I think access controll rule evaluation does not use the same variable replacements like the view method, because defined access controll does not work, and the %GROUPS% (TWikiGroups) table shows the unsubstituted %FORMFIELD{...}% variable, like this:

My Main.FooWebGroup has these relevant lines: (and an added form of course...)

   * Set GROUP = %FORMFIELD{"GroupMembers"}%
Current group members are: %GROUP%

After I set up a value via the attached form to GroupMembers, the Main.FooWebGroup shows the correct substituted value of the %GROUP% variable, but it does not in the %GROUPS% (TWikiGroups) table, and does not work access controll in connection with Main.FooWebGroup.

How can I make form-based-group-membership-modifications work? I have to provide users an easier way to manipulate Set GROUP = lines in groups, than directly editing topic contents.

Yes, that can be... if so, I think that's the wrong evaluation order. Is it able to change the order somehow? Why does not TWiki do substitutions before ALLOW,DENY,GROUP evaluations? I think that would provide a great functionality to TWiki. Form-based things would be very useful.

Let me answer to myself! If I place % EDITPREFERENCES{}% into the topic of the group, it shows an edit button. That does exactly what I need.

Similarily, I want to create dynamic groups based on the %SEARCH{} results of a user's %FORMFIELD(s) . I have a large, frequently changing user set with a %FORMFIELD defining the user's role (poweruser, regularuser, restricteduser, etc). Manually updating the GROUP lists is too much effort. How do I get %GROUPS% to update with %SEARCH results?
