Description

I encountered an issue when trying to import software licenses where most dropdown fields were attempting to inject the text value in the import file rather than the foreign ID from the corresponding table. This was traced back to there being missing dropdown IDs in softwarelicenseinjection.class.php, Adding the missing IDs fixed this for injecting software licenses, however, there was no way to know if there were missing items in other classes.

I saw these options in the injection class were being used to set the displaytype of dropdown, which is later used to determine if a foreign table relation needed to be made. Rather than adding these manually, I've made a change to set the displaytype of dropdown from the rawSearchOptions that are being stored in $tmp.

After making this change and reverting to the original array set in softwarelicenseinjection.class.php $options['displaytype'] = ["dropdown" => [5, 6, 7, 110], I confirmed that I could now successfully inject software licenses.

• It fixes Problem with Relation fields in Software License Injection #444
• Sets the displaytype from the rawSearchOptions in adition to the options manually entered array of options in the injection classes
