      Appkit SDK 4.7.0 Release Notes

      Release date: 22 November 2019

      New features

      • Appkit 4.7.0 adds support for Elastic 7.4.

      • A new filter, find, is added which searches the scope hierarchy to find a specified variable. For example: {{ 'myVariable' | find:this }}.

      Improvements

      • The twigkit.http.filter.DevelopmentErrorFilter is replaced by the twigkit.http.filter.ErrorFilter. If you are using the twigkit.http.filter.ErrorFilter parameter in your web.xml file and an AJAX request fails, a JSON response is received identifying the status code of the REST call and any underlying causes. Previously, an HTML response was received.

        Example configuration:

        <filter>
            <filter-name>ErrorFilter</filter-name>
            <filter-class>twigkit.http.filter.ErrorFilter</filter-class>
            <init-param>
                <param-name>responseCode</param-name>
                <param-value>400,405,406,500,501,503</param-value>
            </init-param>
            <init-param>
                <param-name>excludedPaths</param-name>
                <param-value>/,/login,/login/</param-value>
            </init-param>
        </filter>
      • Accessibility improvements are made to the search breadcrumbs. The text, x, that removed the breadcrumb is replaced by an icon with the alt-text "Remove this term from the query" for use by screen readers.

        Remove this term from the query

      • For security purposes, any existing incoming userID value is removed and replaced when impersonation is enabled.

      • When a user enters incorrect login credentials, the username is preserved in the form and the URL for the user to verify.

      • The UI now sends a X-Requested-With=XMLHttpRequest HTTP header with every API request. This makes it easier for the middleware to detect XHR requests and handle errors appropriately.

      • Previously with the ApplyDynamicSolrDateFormattingResponseProcessor, the same time format was applied to days, hours, minutes, and seconds. Now, these values have their own formats.

      • When using the twigkit.search.processors.response.ApplyDynamicSolrDateFormattingResponseProcessor and twigkit.search.processors.query.DynamicSolrDateRangeQueryProcessor, a new fact value, gap, is added to the date facet. This value of this fact is the unit of the gap size that was applied.

      Other changes

      • The default session timeout is updated from 10 minutes to 1 hour, to align with Fusion 4.2.x.

      Addressed Security Vulnerabilities

      Bug Fixes

      • Fixed a bug that occasionally left a filter styled as being selected after another filter was chosen, despite the query results changing to reflect the new selection.

      • Fixed an issue that would occasionally let a response object from one view be used by another view.

      • Upgraded the JFrog protocol to https to prevent a [FATAL] Non-resolvable parent POM error.

      • Fixed a bug that occasionally caused "like" signals to generate the wrong annotation type metadata.

      • Fixed a bug with FacetFilterValueMappingProcessor mappings which prevented commas from being used with the value. Additionally, two parameters are introduced, separator and key-value-separator. For example:

        separator: ; // Defaults to ","
        key-value-separator: _ // Defaults to "="

        Using key-value-separator: _ will separate the following key value pairs properly: alpha,beta=greek_a,b=english.

      • Fixed a bug that rarely caused a Null Pointer Exception (NPE) error when a workflow platform was reading an underlying platform parameter.
