Hi Rahul,

The error appears when a UI element is bound to a context node or attribute on a node , where this node is defined as : cardinality 0..n or 0..1.

The framework will not create a default empty element in this case.

When the view is to be rendered, its source content doesnt exist. AS the node

has no elements. rendering fails.... Now in your case check for the cardinality. You can try with different cardinalities as per your requirements.

Check also the initialization lead selection property:

For cardinality: 0..n, selection: 0..1, initialization lead selection: false

and for cardinality: 1..n or 1..1, selection: 0..1, initialization lead selection: true

Thanks guys, this thread helped me too.

In my case I had a table of item data. There won't necessarily be any items, so I had cardinality 0..n.

However it makes sense that you can't bind to a context element if it doesn't exist. So I changed cardinality to 1..n - e.g. I always want at least one instance of the node, even if there's no data in it.

Hi Rahul,

In the component controller, put a 'tick' mark on the checkbox "Lead selection". Do this for all the context nodes. Then, activate the entire component.
