KeyTipService - Object null reference

[Mrdec]

In Telerik 2012.Q1.0326.Dev / RibbonView / KeyTipService.cs - line 499 (method HideTips) sometimes throws object null reference exception. In previous version (2011.Q3.1220.Dev) there was a check if (this.popup != null) { ... } and it worked. Now the check disappeared. Please fix it!

Hello Mrdec,

 It shouldn't be possible the popup to be null at any time, but I logged a bug and it should be resolved soon.
Thank you for reporting it.

Kind regards,

It shouldn't be possible but it actually happened. I found 3 places where it throws null reference exception - it's in version (2012.1.0614.40):

line 375: this.tipsStack.Clear();  // should be: if (this.tipsStack != null) this.tipsStack.Clear();

line 499: this.popup.IsOpen = false;  // should be: if (this.popup != null) this.popup.IsOpen = false;

line 657: this.openedRootVisuals.Add(element);  // should be: if (openedRootVisuals != null) this.openedRootVisuals.Add(element);

Sorry, but I really hate this framework. It is the most buggiest code I used. Not because of this bug, but because of the number of bugs you introduce in each new version or hotfix. There is no single version of this framework without problems.

Just been bitten by this one myself.  I am also feeling the pain of using this product.  After using this product for over a year I find I dread updates.

Hi Abdul,

 All the possible Null Reference exceptions are fixed and will released with the upcoming internal builds and the Q2.SP1. 
Please let us know if you have any issues regarding the Ribbon and the KeyTips.

Kind regards,
