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

PawelM — Fri, 25 Jul 2025 18:35:45 GMT

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 :

Perfect support i must say !
