Drop down with Saved Search does not respond to time token change and Submit button present

[altink]

Dear All

I have a Drop Down (named Database) which loads list of options dynamically via a search initially started in a saved-search, saved top of the form. The form has also a time token input and a Submit button. The saved search is bound to the time token (see code below)
The problem is that when I change the time in the time token - the Drop-Down list of values is not refreshed.

Please see the code below, start of the form to Submit button:

<form>
  <label>Scan Compare 001</label>

  <!-- This limits events passed to post-process search -->
  <search id="vln_base">
    <query>
      `mc_vln`
    </query>
    <earliest>$field1.earliest$</earliest>
    <latest>$field1.latest$</latest>
  </search>

  <search id="vln_cmp">
    <query>`mc_comp($field_scan_run_id$,$field_scan_bs_id$)`</query>
    <earliest>$field1.earliest$</earliest>
    <latest>$field1.latest$</latest>
  </search>

  <fieldset submitButton="true" autoRun="false">
    <input type="time" token="field1" searchWhenChanged="false">
      <label>Time</label>
      <default>
        <earliest>-30d@d</earliest>
        <latest>now</latest>
      </default>
    </input>

    <input type="dropdown" token="field_db_name" searchWhenChanged="true">
      <label>Database</label>
      <fieldForLabel>DB_NAME</fieldForLabel>
      <fieldForValue>DB_NAME</fieldForValue>
      <search base="vln_base">
        <query>DEDUP DB_NAME | FIELDS DB_NAME</query>
      </search>
      <change>
        <set token="db_name_no_quotes">$value$</set>
      </change>
      <prefix>"</prefix>
      <suffix>"</suffix>
    </input>
    <input type="dropdown" token="field_scan_run_id" searchWhenChanged="false">
      <label>Scan Id Run</label>
      <search base="vln_base">
        <query>search DB_NAME=$field_db_name$
| stats

      </search>
      <fieldForLabel>SCAN_ID</fieldForLabel>
      <fieldForValue>SCAN_ID</fieldForValue>

      <suffix>"</suffix>
    </input>
    <input type="dropdown" token="field_scan_bs_id" searchWhenChanged="false">

      <fieldForLabel>SCAN_ID</fieldForLabel>
      <fieldForValue>SCAN_ID</fieldForValue>
      <change>
        <set token="scan_bs_id_no_quotes">$value$</set>
      </change>
      <search base="vln_base">
        <query>
          <![CDATA[          
          search DB_NAME=$field_db_name$

    <input type="dropdown" token="field_cmp_code" searchWhenChanged="true">

      <selectFirstChoice>true</selectFirstChoice>
    </input>
  </fieldset>
  <row>

If I renounce using a saved search in the Database drop down, and use a direct search (see code below)

<input type="dropdown" token="field_db_name" searchWhenChanged="true">
      <label>Database</label>
      <fieldForLabel>DB_NAME</fieldForLabel>
      <fieldForValue>DB_NAME</fieldForValue>
      <search base="vln_base">
        <query>DEDUP DB_NAME | FIELDS DB_NAME</query>
      </search>
      <change>
        <set token="db_name_no_quotes">$value$</set>
      </change>
      <prefix>"</prefix>
      <suffix>"</suffix>
    </input>

replaced with

<input type="dropdown" token="field_db_name" searchWhenChanged="true">
      <label>Database</label>
      <fieldForLabel>DB_NAME</fieldForLabel>
      <fieldForValue>DB_NAME</fieldForValue>
      <search>
        <query>index=omega_ds | DEDUP DB_NAME | FIELDS DB_NAME</query>
        <earliest>$field1.earliest$</earliest>
    <latest>$field1.latest$</latest>
      </search>
      <change>
        <set token="db_name_no_quotes">$value$</set>
      </change>
      <prefix>"</prefix>
      <suffix>"</suffix>
    </input>

then the Database Drop Down starts responding to changes in token, it reloads the options list each time the time is changed.

Back into the problematic case with saved search - I can have the Database Drop Down reloaded by pressing the Submit button. But I need to have it respond to the Time Picker (token) - the Submit button is needed for later (in form) dashboards.

My question:
Q1. Why the options list search direct VS / saved-search makes a difference on this?
Q2. How can I have this problem fixed by using saved-search in the Drop-Down?

resolved by enabling Search on Change on the Time component

<input type="time" token="field1" searchWhenChanged="true">
