I wrote a component for ambari and the metrics widgets. However i can't add the widgets for this component. I think i need some help...

my ambari version is 2.5.2 and i check the web problem.
when i open the page of this component page, it shows as

app.js:66933 Uncaught TypeError: Cannot read property 'WidgetLayoutInfo' of undefined    
at Class.createUserWidgetLayout (app.js:66933)    
at Class.<anonymous> (app.js:66874)    
at o (vendor.js:125)   
 at Object.fireWith [as resolveWith] (vendor.js:125)   
at w (vendor.js:127)    
at XMLHttpRequest.d (vendor.js:127)

when i try to add widget.it shows as

app.js:26574 Uncaught TypeError: activeLayout.get is not a function    
at Class.addWidget (app.js:26574)    
at handler (vendor.js:21227)    
at HTMLButtonElement.<anonymous> (vendor.js:13019)    
at HTMLDivElement.dispatch (vendor.js:126)    
at HTMLDivElement.i (vendor.js:126)

finaly i try to create a widgets, the console shows as

app.js:85210 Uncaught TypeError: Cannot read property 'mapProperty' of undefined
