[Sideview] Pulldown chain with interactive dynamic lookups

[Laszlo_K]

I tried to build a multiple filter and each selected value should filter the other 3 filter's value lists, no matter in which order the filters are used. This worked with a simple XML dashboard and a bunch of post-processing searches.
Being a beginner with Sideview, I used a pulldown chain and it works only downstream, as expected 🙂
What should I change to have the desired functionality?
Thank you.

The pulldown chain:

  <param name="name">field1</param>
  <param name="label">Select field1</param>
  <param name="template">field1="$value$"</param>
  <param name="float">left</param>
  <param name="postProcess">|search $field2$ $field3$ $field4$ | dedup $name$ | sort $name$</param>
  <param name="valueField">$name$</param>
  <module name="Pulldown">
    <param name="name">field2</param>
    <param name="label">Select field2</param>
    <param name="template">field2="$value$"</param>
    <param name="float">left</param>
    <param name="postProcess">|search $field1$ $field3$ $field4$ | dedup $name$ | sort $name$</param>
    <param name="valueField">$name$</param>
    <module name="Pulldown">
      <param name="name">field3</param>
      <param name="label">Select field3</param>
      <param name="template">field3="$value$"</param>
      <param name="float">left</param>
      <param name="postProcess">| search $field1$ $field2$ $field4$ | dedup $name$ | sort $name$</param>
      <param name="valueField">$name$</param>
      <module name="Pulldown">
        <param name="name">field4</param>
        <param name="label">Select field4</param>
        <param name="template">field4="$value$"</param>
        <param name="float">left</param>
        <param name="postProcess">| search $field1$ $field2$ $field4$ | dedup $name$ | sort $name$</param>
        <param name="valueField">$name$</param>

        <module name="Search" layoutPanel="panel_row1_col1" autoRun="False">
           <param name="search"><![CDATA[ $search$ | search $field1$ $field2$ $field3$ $field4$ ]]></param>
