Hi MT,

Many thanks for your feedback. I'm sorry for any trouble. This does indeed appear to be a genuine bug within our final release.

This problem will effect any custom troubleshooter tabs you create. This won't effect knowledgebase or download tabs.

This issue would have been introduced within our InstantKB.NET 2.0 RC1 update as we did a number of code optimizations where additional null checks are now required against collections and objects returned from the InstantASP.InstantKB.Business.

I suspect as the bug was introduced late in development this is why it was missed. Thank you for making us aware MT. Now the final version is available we will be addressing any new issues as quickly as possible.

How to Resolve

If you've already started working with & modifying our InstantASP.InstantKB.UI project you'll need to download the file attached below (ViewArticleTRbouelshooterSteps.vb) and copy this into your existing solution.

If you not made any changes to our InstantASP.InstantKB.Ui project you can download the attached InstantASP.InstantKB.UI.dll assebmly and place this into the \bin directory of your installation to resolve this problem.

We'll be updating our 2.0 download this weekend to ensure this issue is resaolved by default. We are also hoping to look at a few rendering issues within IE6 and make a update available before we start the 2.1 development.

For the majority of customers simply replacing your bin\InstantASP.InstantKB.UI.dll file with the one attached below will resolved this problem. IF you have the source code and hve already started modifying our InstantASP.InstantKB.Ui namespace please use the attached source code and replace your existing code with the attached. You'll need to recompile your solution once you've replace the code file.

Thank you again for your feedback MT. I'll be posting a further note within this forum once our main download has been updated to include this fix. If you spot anything futher please do let us know,
