Send context in loop

I am having a problem with the following code:

<t:form t:id="locationsForm" t:zone="myZone">
    <t:loop t:source="locations" t:value="location" t:encoder="locationEncoder">
        <t:textfield t:value="location.name" />
        <t:submit t:event="RemoveLocation" t:value="remove ${location.hashCode()}" t:context="${location.hashCode()}" />
    </t:loop>
    <t:submit t:value="save" />
</t:form>

Say, in the end, the following buttons appear:

<input type="submit" name="button" id="button" value="remove 12339020">
<input type="submit" name="button" id="button" value="remove 2504658">

Pressing any button will only trigger an event onRemoveLocationusing context 2504658.

I assume that the second component of submit overrides the event handler registered with the first, so both of them call the event handler of the second component.

I tried to set it clientIdinto something unique, but that didn't help.

I need delete buttons to submit the same form, as the user can update the name of one element and delete the second in the same operation.
