Has anybody been able to make progress on this?
We are running into this same issue.
Same problem here. It started right after upgrading to Tableau Server 8.
I have a similar issue, I get the same HTTP 410 message when trying to export to a PDF.
This starting happening after the Tableau 8 upgrade.
I have worked with Tableau and they have informed me that it is a bug and a fix will come out with the next release.
As a work around, if you don't use anonymous authentication, The problem does not exist.
Basically, create a user on the server, and assign permissions for that user to the problem workbook.
Then remove the 'All Users' permissions and the problem should not exist.
Users will be asked to login, but you can use the Tableau Server User that you created for all users who need access to the workbook.
We have tested this and found it to work.
Tableau also suggested that removing the embed='y' from the link should also solve the problem, but I have not tested this workaround.
Let me know if this isn't clear.
So we are running 8.0.3 and users are getting 410 error file not found. I thought this was fixed in 8.0?
Probably your the issue you described in your original post is already solved.
I've checked your data visualization in your Tableau Public profile: Workbook: FY14 State Aid Web2
trying to reproduce the error but the export crosstab woks properly, I got the attached file without any problem
Let me know us know if you already get an answer to your problem of if you need additional assistance.
