Add any comments or questions regarding the Taxonomy and Folksonomy tutorial from Issue 58

I have just upgraded our DNN instal to 5.5.1 and figured it was time I looked into the Taxonomy side of things so following your video tutorial I have registered the tag in the skin .ascx file for our site and everything is fine. However as soon as I put the skin object on the page i.e. -dnn:TAGS runat="server" id="dnnTags"- the whole site throws to the DNN error page with the link to return to the site and the following in the address bar.

http://...........Default.aspx?tabi...&content=0

Any ideas on what is causing this or how to prevent it would be appreciated.

Could you post the entire error trace from the Event Log?

Thanks Joe, This looks to be the relevent bit.

Yes. 

Are there any tags defined?

Yes, there are a number of Tags defined and 5 of these have been assigned to pages in the page settings but obviously you can't see them without being able to add the token to the page.

Hmmm ... I'll keep looking. In the meantime, you might want to take this over to the DotNetNuke forums, too.

Thanks Joe,

I have posted that and will let you know if I get it resolved.

I managed to get this sorted out. DNN had somehow added an additional application scope System Vocabulary so there were 2 rows in the database for user tags. Once I manually removed the duplicate row everything was OK (It couldn't be done without editing the database directly).

I followed your videos, but when I go to a page setting or a module setting and select the tags menu, only the first line is displayed. Nothing I created display in the pull down menu. I am running DNN 5.6. Any ideas?

How did you create your tags?

Is there a way to quickly display all tags/tag hierarchy of the site?

Also, the tags do not appear to be searchable via the built in DNN Search. Is this true?

Hello, I have some issues with displaying tag clouds - may be you guys can give me some hint on it....

I did create some tags in admin > Taxonomy

First: none of the tags is displayed in module settings. This is not an issues for me at the moment as I do not intend to use this functionality but may be part of the bigger problem....

Module from Sea Star Software: Displays tags and link to search page results (I have only the trial version) => this works fine!

WatchersNET.TagCloud: displays tags but does not display any results on the search results page => this works half way...

DNN Rad Tag Cloud: does not display any tag (and hence no link to search results) => this does not work at all....

I am running 05.06.02 (144) (this is an upgrade from an earlier version)
Is there any setting in the web config etc. that I need to know?
Many thanks.

Oliver

You might want to check with the developers of those modules to see if they are supposed to work with the tags implemented by DotNetNuke.

Hi Craig, Watchers.net and DNN Rad Tag Cloud are both from codeplex. They do support the standard DNN Taxonmoy... and as I've said they do work to a certain extend...

- the trial tag cloud version from Sea Star Software works fine!
- DNN Rad Tag cloud does not work at all
- watchers.net shows the tags but the search results page is empty...
- watchers.net however works fine if I choose the "common words" option - the search page shows me e.g. on which page I've used the word "business" but this is not what I would like to see...

Many thanks for your help.

Oliver
