Ui-table supports ui_control

[Christian-Me]

Hi Andy,

Rows is not a JavaScript object per se it is a component which can not be transferred to a JSON formatted sting. You can/should access the data by the included methods.

Tabulator - Component Objects

This is why the send method fails.

You can pick the relevant data by using the methods in a new object and send this back to the runtime.

Here is an example for the cell component

Examples for node-red-node-ui-table

Yes ... isn't too difficult. You need a callback function to send the edited data back to Node-RED. Best is to define one for the hole table independent of the type of editor defined for the column: msg.ui_control.tabulator.cellEdited. function(cell){ this.send({ ui_control:{callback:'cellEdited'}, payload:cell.getValue(), oldValue:cell.getOldValue(), field:cell.getColumn().getField(), id:cell.getRow().getCell('id').getValue() }); …

So your error is not directly related to the loopback issue - your error is caused by trying to convert a component to a json string.
