Race condition?

[Scott Arnold]

I’m using a smart table by creating it with this syntax:

window.Smart(divId, class {
  get properties() {
    return {
      dataSource: new window.Smart.DataAdapter({
        dataSource: [],   // initially just empty table
        id: id,
        dataFields: [ ... ]
      }),
      ...
    }
  }
});

After that I use methods like addRow and others to work with the table. Most of the time, this works, but on occasion I get errors like follows:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'boundSource')

This happens on first call to addRow about 5% of the time.

Is the Smart call async maybe? Like can I call window.Smart().then(…)? It seems like I need to somehow wait for the table to finish initializing.

Hi Scott,

We tried to reproduce this without much success. Could you share a full sample which shows the issue you experienced?

Thanks for checking. I’m setting up the table within another web component. I realized that I may just need to do a requestUpdate() after the window.Smart() (or possibly an await requestUpdate()). I’ll try that and see if it fixes the problem.

Will the window.Smart call return an instance of the table? If so, I could also possibly just save that instance instead of looking up the table by ID with a query selector.

Hi Scott,

It does not return an instance of the table so will need to use ID or CSS class querySelector.
