I suspect that your company’s theme is not based on (a recent version of) Atlas UI.
The new layout grid features depend on some new styles. That’s why we check the Atlas UI version to see if those styles are available. If the version number is old or non-existent, you will not get the new layout grid features.
Because you created an app that has already used the new features, but then imported another UI module, the version of the UI module / theme was either to old or non-existent.
To solve this, you can simply change the layout grid properties to make them valid, or ensure you got the right theme version and got the new layout grid styles.
The best way to do the latter is to (backup and) import the latest Atlas UI Resources module, and then merge your company UI module into the atlas UI module.
Another, not recommended way would be to place the 2 files below in your theme folder (with the same folder structure):
Hope this helps.
When using Mendix 8.6 in combination with Atlas UI Resources module 2.4 or higher, by default layout grid columns are set to ‘Auto-fill’ instead of a fixed weight. When opening a Page with such a layout grid in a project that does not use Atlas UI Resources 2.4 or higher, ‘auto-fill’ will be shown as ‘-1’.
I’m not sure what steps you performed to get into this scenario. But I would suggest to try one of these supported scenarios
having the same issue, havn’t done any experimenting yet, but just letting you know, you’re not the only one.
will let you know how we fixed it.
Having the same issue with a atlas3 update, the solution for me was to download the Atlas core module again and replace the existing module on import.
