Topic: Mulitselect not clearing via Javascript, when page rendered with a "selected" value

Expected behavior


should clear the select list.

Actual behavior

select list is not cleared

Resources (screenshots, code snippets etc.)

The clearing of the list does not work under this situation: a) the base HTML page is rendered with the appropriate HTML

  <select id="fldSearchFilterP1" multiple class="select" data-mdb-filter="true" name="p1">
    <option value="v1">Value 1</option>
    <option value="v2">Value 2</option>
    <option value="v3" selected="selected">Value 3</option>
    <option value="v4">Value 4</option>

b) note the "Selected" value c) I need to programmatically clear the list, thus the use of setValue([]).

What I found is: 1) The value doesn't clear 2) If I "click" on any of the check box post page render and then setValue([]), the newly selected value clear, but not the original 3) I have also tried to "dispose" of the instance, clear the select via JQuery (confirmed in the dom) and then re-create it with new mdb.Select(id), upon re-creation "Value 2 " is still selected.

Note: this is strictly cosmetic. When I submit the form, "v2" is NOT submitted (as expected), the value is NOT set at the dom layer.

Any suggestions would be greatly appreciated.

Thanks - initial rounds of testing seems to show that it is working as expected.

I tried the same (and variances of the same concept), abet with jQuery, without much luck. So thanks for a working sample.
