TestComplete object spy cannot catch any HTML5 components which contained within a iFrame.

Hi  experts,

I have recently encountered an issue with TestComplete object Spy.

Object Spy can only recognize the iFrame container but it cannot catch any components (written in HTML5) which contained within this iFrame. The iFrame was contrained with a Flex web application (VMware vSphere 6.0)

I need to develop automation test script against a plugin within vSphere6.0 web client. Is there any solution or workaroud for this issue?

TC10 is using.

Thanks!
