Error message when working with custom view settings with additional restriction enzymes

Issue description

In affected software, an error is produced when saved custom view settings containing additional restriction site enzymes are applied to a sequence view:

If a sequence with custom view settings including additional restriction enzymes is left open when closing the Workbench, the error message appears the next time the Workbench is opened.

Recommendations

Where possible, upgrade your software to a version unaffected by this issue.

The following workaround can be used if you cannot upgrade at this time:

• Open any nucleotide sequence.
• Select "Save View | Apply saved sequence view settings | CLC Standard Settings", and click "Apply".

• Go to “Edit | Preferences | View | User Defined View Settings” and select “CLC Standard Settings” for “Sequence”. Click “OK”.

• After making the above changes, restart the Workbench

Note that it is possible to work with additional enzymes as long as the settings are not saved.

Affected software

• CLC Main Workbench 21.0.1
• CLC Genomics Workbench 21.0.1

This issue was addressed in version 21.0.2 of these applications.
