Demo showcasing issue with missing custom links provided by ResourceProcessor while running Projection
I created simple sample Spring Data REST based web app which has CountryCriterion and Country entities (hence SDR exporter exports countryCriteria and countries resources)
I also created CountryCriterionResourceProcessor which should add edit link, even if you use projection to transform resulting HAL response
In order to reproduce the issue, do the following:
Run boot application
Follow http://localhost:8080/browser/index.html#http://localhost:8080/countryCriteria/1
in HAL browser you can find edit rel in Links section
Follow http://localhost:8080/browser/index.html#http://localhost:8080/countryCriteria/1?projection=withCountries
in HAL browser you can't find edit rel in Links section
