Custom Components (javajet) - This component doesn't support Dynamic Type

[PawelM]

Hello,
I’m building a custom component for Talend Studio 8.x that must support dynamic schemas (id_Dynamic). Although my runtime code correctly handles dynamic columns, Studio still shows a red-exclamation error “This component doesn’t support dynamic type” 

all configuration XML I have tried that, don't fix this issue :

And 3 weeks later, no answer ...  if I ask  what colour should we use, I'm sure I will get an answer very quickly,  hahah green, white or  black,  but any real issues are not in line with marketing, I guess .
Perfect support i must say !
