Known issues in Content Manager Explorer

The following list describes issues that are known to exist in Content Manager Explorer.

In the GUI, the Component Presentation tab has been replaced with a new Design tab

As of SDL Tridion Sites 9, Pages support Regions, which in turn can contain other Regions or Component Presentations. This change results in a change to the Page dialog in Content Manager Explorer: instead of the old Component Presentations tab, showing a table of Components with their associated Component Templates, the Page dialog now has a Design tab showing a tree view of Regions and Component Presentations.

This means that any GUI extensions you may have built for the Component Presentations tab, such as a custom column in can no longer appear in Content Manager Explorer, because that tab no longer exists. The new Design tab is not extensible in SDL Tridion Sites 9.

Chrome and Safari do not show sizing handles for tables and images in a Format Area

In Chrome and Safari for the Mac, selecting an image or table in a Format Area does not make sizing handles appear on the item's edges. As a result, users cannot resize images or tables in this way. To work around this problem, users must either use a different supported browser, or set the width and height of the table or image as numbers.

In Firefox, user cannot select a table by selecting its border

In Firefox, users need to use the Current Elements dropdown to select a table in a Format Area. Selecting the border does not work.

Percentage of Components or Pages with comments or ratings is always 0

For User-Generated Content, the percentage of Components or Pages for which comments or ratings were submitted always remains at 0%, no matter how many items have actually received comments or ratings.

Editing a very large PNG image can cause it to become impossible to save

If you use Image Editor to edit an image in PNG format, its file size can increase by a factor 3. The edited file can then become impossible to save back to Content Manager, because its new size exceeds the maximum allowed upload size (as configured in %TRIDION_HOME%\Web\Web.config. If this happens, you see an error message: "Error saving edited image."

To work around this issue, either ensure that the configured maximum upload size is at least 3 times the size of your largest PNG file, or use images in a different file format (like JPEG) instead.
