Master/Detail

A master detail screen is a combination of a single record screen with one or more dependent multi-record grids

--> See the Panel and Child page for a updated version of Master/Detail.

the Master/Detail screen above consists of two parts, a single record update page (X5a_Update) and a grid with child records (X5b_FB). Both functions are defined as they would be when used independent in Plex-XML

• request-config.xml: like other request definitions but both with an own filter xslt

<webrequest name="X5b_FB">
  <request name="X5b_FB" extends="FindBrowse"/>

    <error type="default" name="DEFAULT"/>
    <reaction type="DEFAULT" target="DISPLAY" localized="true" name="/WEB-INF/limon/filter/X5b_FB.xsl"/>
  </response>
</webrequest>
