Just want to open a link in a New tab

To open a dynamic link in a new tab, you can use the HTML "target" attribute. You would need to modify the code you provided to include this attribute. Here's how you can do it:

  label: "Ticket Id",
  value: a!richTextDisplayField(
    value: a!richTextItem(
      text: fv!row.issueId,
      link: a!dynamicLink(
        saveInto: {
          a!save(local!selectedTicketId, fv!row.issueId),
          a!save(local!showDetailsPage, true()),
          a!save(ri!showLinkedIssues, true()),
          a!save(ri!newShowDetailsPage, false())
        },
        linkStyle: "STANDALONE",
        attributes: {
          target: "_blank"  /* This opens the link in a new tab */
        }
      )
    )
  )
)

By adding the "target" attribute with the value "_blank," the link will open in a new browser tab or window when clicked.

Sorry to be this direct, but this is complete nonsense!

The documentation says: "Defines a link that triggers updates to one or more variables. Links can be used in charts, grids, hierarchy browsers, images, link fields, milestones, pickers, and rich text."

Back to the initial question. As we just learned, a dynamic link does not navigate the user anywhere. Please help us to understand what you want to achieve, and I am sure we find a good solution for it.

Was this reply written by ChatGPT or something?  There has never been an "attributes" parameter for a!dynamicLink() and, at the risk of parroting Stefan who's 100% right, nothing like what was shown here would actually do anything.
