Trigger action is not specified.

Error message

Trigger action is not specified.

What it means

The third required attribute of InputTriggerControl: data-trigger-action defines what happens to the element when the condition matches, and its absence (config.triggerAction === false) throws this error in init(). Valid actions are 'show', 'hide', 'enable', 'disable' and 'empty', combinable with a pipe, e.g. "show|enable" (updateTarget splits on '|' and applies each).

Solutions

1. Add data-trigger-action with a valid action: show, hide, enable, disable, or empty.
2. Combine multiple outcomes with a pipe: data-trigger-action="show|enable".
3. Re-check all three trigger attributes are present (condition, trigger, action) — each has its own missing-attribute error.

Example fix

<!-- before -->
<div data-control="input-trigger" data-trigger="[name=is_company]" data-trigger-condition="checked">...</div>

<!-- after -->
<div data-control="input-trigger" data-trigger="[name=is_company]" data-trigger-condition="checked" data-trigger-action="show|enable">...</div>

var TRIGGER_ACTIONS = ['show', 'hide', 'enable', 'disable', 'empty'];
function triggerActionValid(el) {
    var raw = el.getAttribute('data-trigger-action');
    if (!raw) return false;
    return raw.split('|').every(function (a) { return TRIGGER_ACTIONS.indexOf(a.trim()) !== -1; });
}

When it happens

Trigger: <div data-control="input-trigger" data-trigger="[name=x]" data-trigger-condition="checked"> with no data-trigger-action; supplying a list with a comma instead of a pipe; markup copied from docs examples that omit the action.

Common situations: Authoring dependent-field markup and forgetting the outcome attribute; combining multiple outcomes with the wrong separator (comma) so only parsing of the first happens at runtime even though the attribute exists — but full absence is what throws here.
