When rendering html2 docs, an array of Objects as a body parameter is displayed as "undefined".
The browser console returns the error:
SyntaxError: Error resolving $ref pointer "http://localhost:63342/generation/test/index.html?_ijt=n7smjkttckivilrk3ohtc6e3vc&_ij_reload=RELOAD_ON_SAVE#/components/schemas/Event". (at index.html?_ijt=n7smjkttckivilrk3ohtc6e3vc&_ij_reload=RELOAD_ON_SAVE:2779:318) Token "components" does not exist.

Suggest a fix

The objects within the array are not being dereferenced, so the reference is returned to the view

The following can be added to modules/openapi-generator/src/main/resources/htmlDocs2/paramB.mustache for a point solution, although the dereference method should process this before it is returned.

else {
    schemaWrapper.definitions = Object.assign({}, defs);
    $RefParser.dereference(schemaWrapper).catch(function(err) {
      console.log(err);
    });
if(schema.items.$ref) {
      schema.items = defsParser.$refs.get(schema.items.$ref);
}
