Removing a link (specrelation)? [message #1696946]

Can I remove a specrelation (link) and, if so, how can I do this. When I try to delete, I end up removing the entire row (specobject)

Hi Max,

I think you found a bug, but not quite as you reported it: It looks like the refresh after deleting is missing, which produces a stale editor.

First, I assume that you made the links visible, either by double-clicking on the right column with the link arrows, or by selecting ProR | Toggle all links.

Second, what happens upon delete depends on the Column that is selected: If you select the LAST column, the target SpecObject is deleted. If you select any of the other columns, the SpecRelation is deleted.

But again, due to the refresh issue this does not show. We'll fix this shortly.

Best,

Thanks - I've updated and am looking at this again.

Perhaps I'm misunderstanding how the link works? When I select the column and row, and select delete from the context menu, I lose the entire row including the specobject.

The attached picture shows what I'm doing (couldn't get the context menu in the screenshot though...) Green is what I'm trying to remove, red is what removes...

I'm looking to remove specrelations which I no longer think are correct, or alternatively, point them at different specobjects.

Hi Max,

Okay I think I see the problem: You did not "unfold" the links. You can either doubleclick on the link with the cell information (the one you marked green)., or by selecting Requirements | Toggle Spec relations (there is also a button in the toolbar). Doing so unfolds the outgoing links underneath the SpecObject. Doubleclicking unfolds only the links for one SpecObject, using the menu unfolds them for all.

This is documented in in the handbook, but arguably hard to find: http://formalmind.com/handbook?page=sect0035.html

Hope this helps!

Best,

- Michael

Thanks - toggling that button allowed me to delete, but I think there may still be an issue.

It seems my SpecObject is still removed when I selected and delete the SpecRelation?

The way you did it, it's by design. Smile

You selected the last column and deleted. Selecting the last column is like selecting the target SpecObject. Therefore, the link stayed intact and the targetSpecObject was deleted.

If you select (or right-click) any column, except the last one, the link itself will be removed.

You see the differences also in the Properties View: If you select any column except the last, you will see the SpecRelation's properties. But if you select the last column, you will see the target SpecObject's properties, where you can also edit it.

Best,

- Michael
