Only one modal dialog can be opened at a time.

Hi all,

I got error message "Only one modal dialog can be opened at a time." when try to use Modal Dialog twice.

In first screen, I use Modal Dialog to upload the file by click Browser button and it's upload successfully. In the second screen, I use Modal Dialog again when click on Add Attachment button. The situation is the user want to upload more files after the first one upload successfully.

It show Modal Dialog to browse file, but when I click on Browse button, the error message is shown: 

"Only one modal dialog can be opened at a time."

I tried to searching the solution in Pega Forum and try some solutions below but look like it's not work. 1. Change Target from Modal Dialog to Overlay 2. Add "Refresh-Other harness  

Do you have any solution when I got this message? 

Thank you for your time to see my question.

Hi @DangPhan: PEGA OOTB don't allow to open model window on top of another model window. The error prompt you see is because of this.

For your use case of attaching files, if you are in theme cosmos where you have issue that only one file can be attached at a time, please check this if it helps (Please note the limitations too). If you are using UI Kit, default attachment utility supports attaching multiple files and there is no second modal window required. 

If this is some custom implementation, I suggest to check if the UI design can be updated to use OOTB. Please let us know more details on what issue you are facing on overlay.

Please also look into this for some additional info.

Thanks.

@ArulDevan Thank you Devan. I tried to change some properties from Menu and I found another solution can be use in this case. Changed it to Overlay and it's worked with a little bit issue. We will try more to find out how to fix it completely.

Here is the link I found out in our community. Error:Only one modal dialog can be opened at a time | Support Center (pega.com)
