See please the first part of the old defect:

Steps to reproduce:
1 Navigate to https://jdi-testing.github.io/jdi-light/index.html and open the Developer console (F12)
2 Select JDN
3 Check the tab 'Warning'.

Expected result:

The 'Warning' tab of JDN is always looked as active even before the first generation
AND
it never contains any records about any finished generations.

Steps to reproduce:
4. Generate the pageobjects via button 'Generate' or 'Generate several pages'.
5. Open 'Warning' tab.

Expected result:
Records about problems or success are presented.

Actual result:
There aren't any records in any case.
