Duplicated _Code_Art ListPermissionExtention


Hi CodePlex,

After we installed the CodeArt permission web part to our SharePoint 2010 server, it creates _Code_Art ListPermissionExtention list in each site for recording the permission configuration. However, we found in some sites, there are multiple/duplicated _Code_Art ListPermissionExtention lists were being created (from 2 to 7 lists with the same name) which casued the backup of the site collection cannot be imported.

When we create a new sub-site where the web part was not activiated yet, no _Code_Art ListPermissionExtention was being created when the site was first created. We've checked the site one day later found there were 6 _Code_Art ListPermissionExtention lists contained already. The site was a testing site and no one touched it during the day.

It's very strange. I never meet this issue.
every time, you change the permission setting or view the form page. sppex will check if the list with title _Code_Art ListPermissionExtention exist. if it doesn't exist, sppex will create this list.
it means that the list will be create only once.
soo... I don't know why this happend.
can you provide me more information, for example:
the url of such lists.

Thanks for your reply. The maximum number of duplicated lists that we found were 7 of them. The web part was used on our internal SharePoint site which we would unable to provide the url. The duplicated lists are not possible to be created manually.

Hi, I guess your site must have a lot of users.
maybe this is caused by the thread.
I have add the lock logic in the new version.
you can try the 1.52 version.
