Research direction

Start by reproducing the reported interaction between a draggable container dialog, the MaterialTable, and the attachments state using the code sample in the issue. Trace whether adding an attachment reaches the state update and table data, and consider the issue resolved when the table responds to state changes while the dialog remains draggable.

Written by the indexing model from the issue text.

Description

I have a MaterialTable that is bound to a state variable that contains an array. It works beautifully, until I make the container dialog draggable.

... const [attachments, setAttachments] = useState([]); ... const onOkAttachmentHandler = (file) => { //add attachment if (file !== null) { let attachment = { ownerId: props.entityId, labId: props.labId, filename: file.name, file: file, archive: false }; setAttachments((previousAttachments) => { let newList = [...previousAttachments, attachment]; return newList; }); props.attachmentAdded(attachment); } setAddAttachmentDialogVisible(false); } ... <MaterialTable title="Attachments" data={attachments} ...
