You seem to have a custom block_unsearchable template. What is its content?

[mlwebworker]

Nein es gibt kein individuelles Template block_unsearchable von mir.
Was der Catalog-Manager an dieser Stelle tut, habe ich noch nicht genau herausgefunden.

[fritzmg]

Nein es gibt kein individuelles Template block_unsearchable von mir.

According to the error message you are using a custom template:

  at templates/block_unsearchable.html5:3
  at include('/srv/www/mlweb/public/ml-webseiten.de/projektentwicklung/hebammenlisten/templates/block_unsearchable.html5')

[mlwebworker]

So gesehen hast Du Recht. Ich habe mir die Variablen angeschaut, die zur Verfügung stehen und wahrscheinlich daraus dann die Fehlermeldung gezogen. Der Fehler tritt aber genauso ohne dieses Template auf.
Hier der Vollständigkeit halber der Code des Templates:

<?php $this->dumpTemplateVars() ?>
<!-- indexer::stop -->
<div class="<?= $this->class ?> block"<?= $this->cssID ?><?php if ($this->style): ?> style="<?= $this->style ?>"<?php endif; ?>>

  <?php $this->block('headline'); ?>
    <?php if ($this->headline): ?>
      <<?= $this->hl ?>><?= $this->headline ?></<?= $this->hl ?>>
    <?php endif; ?>
  <?php $this->endblock(); ?>

  <?php $this->block('content'); ?>
  <?php $this->endblock(); ?>

</div>
<!-- indexer::continue -->

I have the same problem and do not have a custom template

 Actually, there are a lot more warnings everywhere also in the backend.

[fritzmg]

This error also occurs with the regular block_ templates. The reason is that ContentCatalogFilterForm executes

$this->objForm->render( $this->Template );

in its compile() method. However, at this point $this->Template does not yet have the correct template variables set. This would happen after the compile() method is called by parent::generate().

I don't quite understand how ContentCatalogFilterForm is supposed to work. $this->objForm->render( $this->Template ); would return the rendered template of the form - however, this is then never used.
