Bug #91382
Updated by Jonas Götze about 4 years ago
When using a fluid ajax widget (custom or from core, e.g. autocomplete widget) which stores its configuration in the session you get an Exception: >#1588178538 TYPO3\CMS\Fluid\Core\Widget\Exception > >Widget configuration items either must be null, scalar, array or JSON serializable, got "TYPO3\CMS\Extbase\Persistence\Generic\QueryResult" <pre><code class="html"> <input type="text" id="myautocomplete" name="myautocomplete" /> <f:widget.autocomplete objects="{news}" for="myautocomplete" searchProperty="title" /> </code></pre> This is because the security related change here https://github.com/TYPO3/TYPO3.CMS/commit/e4fb92a85bed8067d45d2c25c4b559642f206248 which does not accept such an object as it is not JsonSerializable. Though I am unsure about where and how this should be fixed.
