How to display list of documents in a container using custom widget(development)

Hi,

I am new to Jive development, learning and working on custom widget development. I have developed a custom widget which shows all documents in the container.

My issue is not able to display list of documents on FTL and please explain me how to use existing FTL template's in custom widgets.

I'm getting values(Logger) from Java but not able to render on FTL template.

Can anyone help me to fix this issue and also help me to use use existing FTL template's
