Appkit SDK 4.7.0 Release Notes

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 }}.

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.

<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.

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.

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

Upgrades to Jackson 2.9.10 and Apache Commons BeanUtils 1.9.4 are made to address CVE vulnerabilities.

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 "="

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