Hello,
Thank you for your feedback.
Regarding the issue description, it looks like Joomla 4 doesn't know how to handle a form with pre-check fields.
To fix the issue, you can edit the backend view "views/vendormarket/tmpl/delete.php" and replace
By
</form>
<?php
$doc = JFactory::getDocument();
$doc->addScriptDeclaration('window.hikashop.ready(function(){Joomla.isChecked(true);});');
And the Joomla 4 "Delete" toolbar button will be enabled.
Regarding the Joomla 4 bug details.
It's in the "joomla-toolbar-button" javascript file :
github.com/joomla/joomla-cms/blob/4.0-de...utton.w-c.es6.js#L49
By default, the button is set-up disabled
if (this.listSelection) {
this.setDisabled(true);
}
When it register to check the modification of the field value
this.formElement.boxchecked.addEventListener('change', this.onChange);
It should also read the current "boxchecked" value in order to set the "disabled" state, like it's doing in the "onChange" function.
Regards,
