typo3 6.1.0
indexed search

I get this error after installing indexed search.

Oops, an error occurred!

PHP Catchable Fatal Error: Argument 2 passed to TYPO3\CMS\Form\Controller\FormController::cObjGetSingleExt()
must be an array, null given, called in

Solution

After uninstalling extension system extension form it works

=> This solutions works, but not really a solution if you want to use the form system extension.

sorry for the bad error message from thomas.

thanks to koen van nuffelen, but * we need the form extension installed.*

the error message is:

PHP Catchable Fatal Error: Argument 2 passed to TYPO3\CMS\Form\Controller\FormController::cObjGetSingleExt() must be an array, null given, called in D:\wamp\www\psroggwil\typo3\sysext\frontend\Classes\ContentObject\ContentObjectRenderer.php on line 732 and defined in D:\wamp\www\psroggwil\typo3\sysext\form\Classes\Controller\FormController.php line 93

we have the problem without the indexed search extension installed (only with the placed search content element)!
so i think the category indexed search is wrong. I think it shoud be Form wizzard.

Indeed. Uninstalling the Form sysext "fixes" the issue.
You can also apply the changes proposed in this patch:
https://review.typo3.org/#/c/6537/

The changes in https://review.typo3.org/#/c/6537/ solve the crash issue but standard search not working properly, the form is not displayed correctly. I get
###LABEL### ###FIELD### as output for the search field.

As #31572 was merged, does this issue is resolved in latest TYPO3?

Das the issue with "###LABEL### ###FIELD###" still exist?

Yes, it still exists. The following line solves the problem:

in /typo3/sysext/form/Classes/Controller/FormController.php
line 107
'10.' => is_array($mergedTypoScript) ? $mergedTypoScript : array(),

Ok, would you like to provide a patch against master by using Gerrit? http://wiki.typo3.org/CWT

Sorry, I have to correct myself: The standard search form still isn't displayed, the only difference between the two patches is that with our patch, no form is displayed at all (no labels either). I had to add the form manually via html, the standard search is still working though.

So which TYPO3 are you running now?
And which issue is left (without using a patch)?

TYPO3 version is 6.1.7
Without using a patch i get Label code displayed but no search form. The search itself is working.

Ok, can you please add an illustrative screenshot?

I can confirm the non-replaced labels with current 6.2-master and the default search-form.

Problem appears if EXT:form is installed, no matter if its static template is loaded or not. Thanks to Olly for the clarification. If you can, deactivate EXT:form for the moment.
EXT:form "overlays" the form-functionality and produces the undesired output.
