Thanks for the answer Mik.

But, Isn't it strange that this situation can occur randomly??
Or is there any particular case, when we always need to use the solution,
like the one you provided.

I am asking it because I had written other components in my code where
everything is working seamlessly and I am worried now as if they are error
prone??

Thanks,
Manu.
