1: after-unmount callback?
Posted by Ola Hansson on 10/17/03 11:23 AM
Is it too late to add a new type of callback? Is it hard to do?

The reason I ask is that I've found it practical (necessary?) to perform a cache flush call to get rid of the curriculum bar after you have unmounted the instance from the sitemap, without un-instantiating it.

Currently, the bar is removed only if the instance is deleted.

For 5.0, yes, definitely.

Any reason you can't use before-unmount?

Never mind, I take back my proposal - when I think about it some more callbacks wouldn't have helped me anyway.

Actually, this is solved by the new check I'm using in site-master.tcl, which finds out if any curriculum instance is mounted in the sitemap under the current subsite, in order to know if the bar should be displayed or not.
