ParentPageDialog.aspx bug for Content Administrators

When a user who is a Content Administrator but not an Administrator attempts to set the parent page of a page, and the number of pages has gone over the threshold where it switches to using the popup tree view, they get a server error. This appears in the log:

2013-05-16 16:20:12,187 ERROR 82.69.43.209 - en-GB - /Dialog/ParentPageDialog.aspx?pageid=682 - mojoPortal.Web.Global -  Referrer(https://cmsidocumentation.esdm.co.uk/Admin/PageSettings.aspx?pageid=682) useragent Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31

I've had to make this user a full admin to fix this...

Re: ParentPageDialog.aspx bug for Content Administrators

There must be some additional factor involved. I'm not able to produce this error just by launching the parent page dialog as a user in Content Administrators role.

Re: ParentPageDialog.aspx bug for Content Administrators

It was very clear cut on our site: when I made the user Admin >> no error, when he was only Content Admin >> error.

What other information can I give you to help track this down?  Would you like an admin account on the affected site?

Re: ParentPageDialog.aspx bug for Content Administrators

I think there must be some factor involving the page hierarchy and edit roles or something, I really don't know what, I just know I am not getting an error. Does it happen on any page for you or just a specific page or when there is a specific parent page?

Re: ParentPageDialog.aspx bug for Content Administrators

I have replicated this problem exactly on a different site, but one which is a child site of the one that originally produced the error. Does that help? I could send you the database if you want.

Re: ParentPageDialog.aspx bug for Content Administrators

And I've now reproduced the problem on a completely unrelated site (actually same web server, but different web site and database) that also has sufficient pages to make the parent page setting use the popup.

And I've tracked the problem down to the use of this setting:

<add key="ParentPageDialogExpansionDepth" value="-1"/>

If I change this to <add key="ParentPageDialogExpansionDepth" value="1"/> (or 2) then the problem does not occur. So for some reason, the tree is failing to expand fully for users who are Content Admin but not Admin. Hope this helps track down the bug?

Re: ParentPageDialog.aspx bug for Content Administrators

Thanks! With that additional information I was able to produce the problem and fix it. I've patched the 2.3.9.7 release with this fix. The only changed file is /bin/mojoPortal.Web.dll

Best,

Joe
