TYPO3 Core

in general it should be enough to have a look at the old sources

i checked user with only access to live workspace: the selector disappears, only the icon stays (should be removed)

The other checks has to be integrated as well like cache links.

i integrated the workspace access check from old source, please have a look

After talking to Ingo in IM i made a patch and extended the interface with checkAccess-Method. If this method returns false, whole module toolbar item is not rendered.

I changed all backend toolbar-modules and added this method returning true and marked as TODO
Workspacemodule does a real check here

@Benni Mack: opendocs has this method also, you can integrate the basic check.
Additional checks for single items should take place in module->render()-method.

access checking for toolbar item is prepared now, check out svn revision 3224

resolved by fixing #17381 and #17381
