Show a custom field in a block I 'm getting crazy trying to show a value of a custom field (now in core) in a sidebar block. I have tried to show it with the render function, calling directly the field, with no luck.

I have a custom content type named "content1" and a  custom field named "field_test1"; I want that value to be shown on a block that will be visible while viewing the page node.

Do you have any suggestion on how to do it?
I would use the following code, to render a field.

render(field_view_field('node', $node, 'field_test1'));
