the class ProjectPortletUtils method getExcludedLicensesPerAttachmentIdFromRequest.

/**
 * Returns a map of excluded licenses. They key is an attachment content id, the
 * value is a list of excluded licenses.
 * <p>
 * For this method to work it is crucial that there is a so called
 * "license-store-&lt;attachmentContentId&gt;" map in the session. This map must
 * contain a mapping from a key to a {@link LicenseNameWithText} object.
 *
 * @param attachmentContentIds list of attachment content id to check for exclusions in the
 *                             request
 * @param request              the request containing the excluded licenses as parameters
 * @return a map containing the licenses to exclude
 * @see ProjectPortletUtilsTest for a better understanding
