Link-multiple checkbox not saved for old relationships after upgrade

[yuri]

If after upgrade to v9 you can't save the Link Multiple checkbox for relationships created earlier, try the following.

Save the relation without Link Multiple checkbox checked. Then, you should be able to save it checked.

Note that if you used entitynameIds variables in workflows in v8, those variables are not available in v9 (and workflows will not work correctly) unless you tick the "Link Multiple Field" checkbox in relationships. Note also that the "Link Multiple Field" checkbox is NOT saved on first attempt. You will first need to check the Auditing tickbox, then save and then edit again and then tick the "Link Multiple Field" checkbox. If Auditing is not available then activate streams for that entity first.

I'm not sure checking Audited is necessary. It worked for me without checking it.

Before v9, the link-multiple field was created always, but suppressed in some way if the checkbox was unchecked. Now, it is created only if the checkbox is checked.
