Prod build exception

Question

We have a few controls being used - but in run time datepicker blows up with an exception:

ERROR TypeError: l.registerEvents is not a function
which points to: _this.registerEvents(outputs); in the DatePickerComponent constructor.

This only happens for a --prod build. Works just fine otherwise.

The versions we're using:
ej2-angular-calendars": "^16.2.52"

angular cli: 6.0.5

fyi these are all the other loaded modules:

[ButtonModule, DropDownListModule, DialogModule, AccordionModule, TooltipModule, DatePickerModule];

Hi Jatinder,  
 
 
Sorry for the inconvenience.  
 
 
We were able to reproduce the reported issue and have confirmed this as a defect and logged an issue report for this. The fix for this issue will be included in our upcoming patch release. We appreciate your patience until then.  
  
 
In meantime, we would like to suggest the below workaround solution to resolve this issue in application level by setting ‘optimization’ property as false in angular.json file.  
 
  




[angular.json]   
   
          "configurations": {   
            "production": {   
              "fileReplacements": [   
                {   
                  "replace": "src/environments/environment.ts",   
                  "with": "src/environments/environment.prod.ts"   
                }   
              ],   
              "optimization": false,   
              "outputHashing": "all",   
              "sourceMap": false,   
              "extractCss": false,   
              "namedChunks": false,   
              "aot": true,   
              "extractLicenses": true,   
              "vendorChunk": false,   
              "buildOptimizer": true   
            }   
          }   
   
 
 
Please let us know if you have any further queries.  
 
  
Regards,  
 
Deepa L.

Thanks, that unblocks us for now.But with no optimization the bundle sizes are insane.Any idea when the patch is expected to be released?  and what number will that be?Also i hope either the patch notes indicate this fix or if you could message back on this thread; so we can track it.
