WebDynpro for ABAP - Cardinality Violated!

I get the following error:

 The following error text was processed in the system MIE : Number of Elements of the Collection of Node COMPONENTCONTROLLER.1.PRELM_PARTS Violates the Cardinality. 

When running my WebDynpro Application - it's output on a web browser screen that looks like this:
Basically what I've done is tried to code a table onto a Node that I've set Cardinality of 0-1.
I need a 0-n cardinality.
So I go back into my populating Method - it's got the following code, which ties the table to the node : 
  wd_node = wd_context->get_child_node( name = 'PRELM_PARTS' ).
  wd_node->bind_table( new_items = t_prelm_parts ).

But if I look at the Context node, I can see that it has a 1-1 cardinality



By re-defining this as 0..n I can bind a table to it.
In this case, the Context Node was mapped from the Component Controller Context Node, so I had to redefine that, and then update the mapping.
