uncaught at t TypeError: Cannot read property '_currentElement' of null

[Greg]

Hello,

I am getting the following stack trace error when using EmbeddedArrayInput one inside another one

My JSON payload look like:

{"id":"stcuEchLoadid_9",
"name":"Channel name",
"metadataSet":[{"locale":"en_GB","metadata":[{"key":"Title","value":"channel 01 title"}]},
               {"locale":"none","metadata":[{"key":"another key","value":"another value"},
                                            {"key":"a key","value":"a value"},
                                            {"key":"Rating","value":"1"}
                                           ]
               }]}

and my JSX like:

    <Edit title={<ChannelTitle />} {...props}>
      <SimpleForm>
        <DisabledInput source="id"/>
        <TextField source="name" validate={required}/>
        <EmbeddedArrayInput source="metadataSet">
           <TextField source="locale" />
             <EmbeddedArrayInput source="metadataSet">
               <TextField source="key" />
               <TextField source="value" />
             </EmbeddedArrayInput>
        </EmbeddedArrayInput>
      </SimpleForm>
    </Edit>

forget it... I was using <TextField> instead of <TextInput> on an <Edit> view !
