Preview is missing on Modal - Is Preview considered as Modal when Nested is attempted?

[RahulKakunuru]

Hello everyone,

We ran into an issue with nested modals in Constellation while trying to build a workaround for tooltips.

We need to show tooltips on read-only fields. Since this isn’t available OOTB, we set up a workaround using a Case Reference with New Views. This triggers a modal dialog showing the text we need, and it works perfectly on our standard screens.

The problem starts when we show multiple cases in a table that is configured to “Edit in Modal”. When the user opens that edit modal, we display the same read-only data with our tooltip workaround. However, instead of triggering the preview modal like it usually does, it just defaults to an “Open in New Tab” link. This completely breaks the UX we are trying to achieve.

Does anyone know what options we have to deal with this? Is there a better way to handle tooltips on read-only fields when you are already inside an edit modal, or is this just a strict limitation in Constellation?

Thanks!

Tool tip is available in 24.x onward. Please configure Additional Information to show the additional details as a Tool tip

Which also works when read only (tested in '25)

Instead of using the Case Reference and New Views modal as a tooltip workaround, use Pega’s built-in Additional Information setting on the field, available from version 24.x onward. Configure this setting to display your text as a native tooltip instead of triggering a modal. This works even on read-only fields and even when the field sits inside a table row that is already open in an Edit in Modal screen. Because no second modal is ever opened, the “Open in New Tab” fallback never gets triggered. This fully removes the nested modal limitation you were facing.
