Use of QDT-components in Mashup

[alan_grn]

I am building a react mashup using qdt-components.

I have got the code working so that filters etc work.as well as selections on the qdtTable.

I am now trying to bring in an third party library- fusion charts..I have been able to render the chart correctly but get an error when I run the select function on the chart. I have used the same code for Fusion Charts to create a mashup using the qlik-react-starter so I know that version works and I can make selections using that implementation.

Uncaught (in promise) Error: JSON parse error

    at Intercept.errorInterceptor

My select function is below and e is a numebr which matches the qElemNumber.

  select = e => {

    this.props.select(Number(e), 0);

  };

Any ideas how to correct this?
