Studio Pro freezes when opening a page with nested snippets

Issue

When opening a page in Mendix Studio Pro that contains multiple nested snippets, Studio Pro becomes unresponsive and displays a Not Responding message.

While the affected page is open, Studio Pro does not respond to interactions. Closing the page restores normal functionality. The page continues to run correctly when the application is started locally or deployed to another environment. The issue only occurs when Studio Pro attempts to load the page in the modeler.

Environment

• Studio Pro 10.24.x
• Applications containing pages with nested snippets

Cause

The issue occurs when a page contains multiple nested snippets, where one or more snippets are embedded inside another snippet. The complexity of rendering these nested snippets cause Studio Pro to become unresponsive while loading the page in the modeler.

Solution / Workaround

As a workaround, temporarily remove one or more nested snippets from the affected page to reduce the page complexity while making changes.

To apply the workaround follow the below steps:

1. Remove one or more snippets that are nested within another snippet.
2. Save the project and reopen the page.
3. Make the required changes.
4. Re-add the removed snippet or snippets and save the project.

Several improvements related to snippet rendering have been introduced in Studio Pro 10.24 and 10.24.18. Upgrading the project would mitigate this issue.
