I have a problem with multimedia components on my Java DXA 1.7 implementation, we have a Download list, which accepts multimedia components, by using WebComponentMetaFactory we read the component's metadata and try to read the title from there.
WebComponentMetaFactory wcf = new WebComponentMetaFactoryImpl(publicationId);
ComponentMeta componentMeta = wcf.getMeta(tcmIdComponent);
return componentMeta.getTitle();
After executing that code I will get as a result a string which seems to be the JSON path for the multimedia component
tcd:pub[1262]/componentmeta[257020]
I can achieve obtaining the title of the component for other types but seems not to work for Multimedia components.
