   [5.0.2.1559] cacheFlexes: Cannot read property '1' of null

   
   
   
   

   
   

   I receive following error when I resize window to 1px width.
   

   Layout:
   
   TabPanel with responsive tabBar (top/left) containing gridpanel with booleancolumn. This error appears when child is booleancolumn.

   
   

   Currently I fixed that error with small condition:

   
   

   
   

   Code:

   
   

   
   cacheFlexes: function (ownerContext) {
   ...
       match = percentageRe.exec(child[names.width]);
       if (match) {
           childContext.percentageParallel = parseFloat(match[1]) / 100;
            ++percentageWidths;
       }
   ...
   }
   

   
   I try prepare testcase for you.
