Values not found for the selected row.

Error message

Values not found for the selected row.

What it means

After the component check passes, onGetInspectorConfiguration looks up the snippet by code via SnippetManager::instance()->findByCodeOrComponent(theme, snippetCode, componentClass). A null result — no snippet registered in the current theme with that code — throws this ApplicationException with the code substituted for :code. Snippets are theme-scoped: the code must match the `code` setting of a snippet partial or a registered component snippet in the active theme.

Solutions

1. Open the snippet partial in the active theme and confirm its `code = "..."` setting matches the posted code exactly.
2. Check the correct theme is active — snippets resolve only within the current theme via SnippetManager.
3. If the snippet comes from a component, make sure the providing plugin is installed and enabled, then re-save the content that uses it.

Example fix

{# before: partial has code = "cta-box" but request sends old code #}
component: '', snippet: 'cta'  -->  ApplicationException

{# after #}
component: '', snippet: 'cta-box'

// Server-side: verify the snippet exists before opening its inspector
use Cms\Classes\SnippetManager;
$snippet = SnippetManager::instance()->findByCodeOrComponent($theme, $snippetCode, $componentClass);
if (!$snippet) {
    // refresh the snippet list instead of requesting configuration
    return Flash::error('Snippet "'.$snippetCode.'" not found in the active theme');
}

try {
    $config = $widget->onGetInspectorConfiguration();
} catch (ApplicationException $e) {
    // 'Snippet with the requested code ... was not found in the theme.'
    // -> reload the snippet palette for the active theme
}

When it happens

Trigger: Posting `snippet: 'old-code'` after the snippet partial's `code` setting was changed or the partial deleted; switching the active theme so previously available snippets vanish; a typo in the snippet code string; a component-based snippet whose plugin is disabled.

Common situations: Renaming snippet codes during a content refactor; theme switching in a multi-theme setup; editor sessions holding stale snippet codes across deploys; plugin disablement removing component snippets.
