Update of LiveComponent fails with error "component ABC with ID XYZ does not exist or it has been removed"
Hi,
I’m rendering a live component in a for loop:
<%= for mapping_form <- inputs_for(f, :mapping) do %>
...
<.live_select
form={mapping_form}
field={:source_field}
phx-target={@myself}
options={source_field_option_list(@changeset)}
update_min_len={0}
/>
<% end %>
“live_select” renders a live component. What I want to do is to update the component dynamically using send_update:
send_update(LiveSelect, id: id, options: options)
This fails with the error:
send_update failed because component LiveSelect with ID "custom_mapping[mapping][0]_source_field_live_select_component" does not exist or it has been removed
However, when I inspect the DOM, I see the live compnent is there and has the expected id custom_mapping[mapping][0]_source_field_live_select_component
I’m kind of puzzled by this issue, as far as I know sending updates to LiveComponents should work even if they’re rendered in a loop.
Wondering if anyone can give me a hint or can think of any reason that would cause the LiveComponent not to be found by LiveView.
Thanks!
P.S: using the new <.inputs_for> component instead of the loop didn’t change anything

The id you need is the one you use with
<.live_component id="…" />, which doesn’t necessarily match what is rendered to the DOM.Edit:
Also consider this:

Nope. I know for sure that it does.
I know about the PID thing too. It’s all the same LiveView process

hahah absolute brain fart
I was using the wrong module name: it should be
LiveSelect.ComponentnotLiveSelect.And I wrote the damn library!! I should go back and read my own docs
In my defence: It’s been a really hard week for me. I will close this topic and sorry.
