Zero Messages in Thread when using pageNumber and pageSize :(

Can you post an example of a board with more than 10 threads where this isn't working for you?  The example you give is for a board that doesn't appear to exist.  Here is a quick example I tried, but it worked correctly for me.

http://hificommunity.lithium.com/restapi/vc/boards/id/Amplifiers/threads/recent?page_size=10&page=1

http://hificommunity.lithium.com/restapi/vc/boards/id/Amplifiers/threads/recent?page_size=10&page=2

http://hificommunity.lithium.com/restapi/vc/boards/id/Amplifiers/threads/recent?page_size=10&page=3

I have the same issue. I have 1200 threads in my board. The first query with page=1 and page_size=1000 works perfectly fine. The next query with page=2 gives error. The <linear> tag data is blank or missing. Please help !!!

Waiting for a solution........ :mansad:

Hi anilbpai , I can't seem to reproduce this issue on my side.  Can you private message me some calls I can make against your stage site to reproduce the issue?  I'll report back to this thread after I'm able to reproduce and diagnose the problem.  Thanks!

jameel_khan Could you post the call you're trying? The one you mentioned doesn't return anything because it is invalid. I tried following call from lithium community for developer section, and it is working fine all the way down to 169th page.

http://community.lithium.com/restapi/vc/boards/id/studio/threads?page_size=10&page=100

http://community.lithium.com/restapi/vc/boards/id/studio/threads?page_size=10&page=169

No response here on 180th page as the count of threads is 1685, so there will be an empty threads tag, but it works fine until it keeps getting the content.

I looked at this again and believe I found the issue.  If you look at the <linear> node in the response for any of the pages after page 1, you see that it's blank (<linear/>).  It looks like the logic is implemented in such a way that it's paging through both the threads and the replies to those threads (which show up in the <linear> node).  So when you specify page=2, it is returning you the second page of results for threads but is also returning you the second page of results for the replies that go in the linear tag -- for many threads, there is not a second page of replies and so the <linear> tag shows up as blank.

To test this out, create a new thread in the community, then do a threads/recent call with page=2&page_size=1 -- you'll see a blank <linear> tag in the results.  Now post a reply to that thread and do the threads/recent call again with page=2&page_size=1.  Assuming no one else has posted a new thread in the meantime, you should get the same thread back, this time with the reply you gave in the <linear> tag.

This is strange behavior to say the least and there is a bug filed for it.

You should be able to work around this problem by using either the topics/recent call then doing a /threads/id/<thread id>/messages/linear call for each thread returned in the results (you could combine the 2 calls in an endpoint if needed).

We have 1400+ threads and it keeps on increasing.... It will take 1 call for first 1000 threads and another 400+ calls for other threads. It keeps timing out and causes issues. Please fix the issue and let me know. Thanks once again.

We have a new version of our REST API coming out very soon, which will include a query language that will allow you to retrieve this information in a single call.  In the meantime, you could create an Endpoint in Lithium Studio that combines these calls (so you only have to call one endpoint over HTTP).
