Hi Khiem,

It seems on server side that you are not able to get get values form the table (which will be dynamic) as shown in your "Error log line 7". For this to work you will have to use Instance Option (option schema), to provide Table name, configure filtered list and set appearance of you search result.

Please find link for this widget: Data table from Instance Definition

Let me guide you to create Inctance option:

1. You clone the widget and add it to your page

2. Now click on Edit button  (pencil icon)

3. Instance Option dialog will get open

4. Fill all the values such as table, filter, fields, etc

5. Save it

Now you will be able to see your filtered query, as I have configured for Change. Please find below image:

Please mark my answer as Correct/Helpful if that helped you anyhow.

Regards,

Hi Khiem,

I just tried it, and it did worked again for me. Currently, which version are you using?

The list should also get displayed in Edit view (where you add containers), as seen in my last post image. Is that showing you properly?

Another way,go through Service Portal > Portals > click on your Portal name > click on Try It (first you need to add your page in Homepage field of Portal), and check if same issue persists.

Also, can you please share your screen-shot of Instance option, as what you have defined in that I want to see.
