And in fact you don't need to use a value link for triggering a
command, a normal link with the command parameter is enough:

  */some/page/to/edit|command=Edit*

Note that in both cases this goes through the security system.

Ok, everytime I think I have a useful idea it is already there and better implemented :) It is nice that I can do it either one or the other way. But the link text is always the title of the target structure. I need the link label to be displayed. In the second approach can do it manually with *Label>/some...* (does not work with the first approach *Label>value:...*. Is there a way to display the link label? 

thanks,

Actually this is already implemented, for example:

Also works with all other value-links that list or return structures,
e.g. children, references, parent, previous, random, siblings, find,
...

I'm trying to create a value link that can display a single command inside a document. But I struggled to create a proper link for the command. This seems only possible if you have a pier context and renderer at the same time which is not really the case as long as you are staying inside PRValueLink.

The only solution I could come up with is the following:

PRValueLink>>commandIn: aContext
       <value: 'command' comment: 'Display command as link'>
       (PRCommand withAllConcreteClasses
               detect: [ :each | each label = (self parameterAt: 'label' ) ]
               ifNone: [ ^ nil ])
                       ifNotNilDo: [ :commandClass |
                               ^ [ :html |
                                       html anchor
                                               goto: (aContext command: commandClass new);
                                               with: commandClass label]].
       ^ nil

I have the impression there might be a solution without using a block. Any ideas? Or is it ok the way it is?

thanks,

Norbert
