`solr:form` VH does not find TypoScript settings when plugin was instantiated via `EXTBASEPLUGIN`

[snk-spo]

I render the following via <f:cObject typoscriptObjectPath="lib.searchBar"/>

lib {
  searchBar = EXTBASEPLUGIN
  searchBar {
    extensionName = Solr
    pluginName = pi_search
    settings {
      search {
        targetPage = {$pages.search}
      }
    }
  }
}

to have the search bar available centrally in the navigation. But calling <solr:form> in the Form Fluid template does not respect the targetPage in any way,even though it is in the settings array, so f:uri(pageUid: settings.search.targetPage) works! Only the <solr:form> does not find it. If I also set plugin.tx_solr.search.targetPage = {$pages.search} it works, however.

Expected: The configuration in the EXTBASEPLUGIN should be found and also win over the global TypoScript, because everything under EXTBASEPLUGIN should effectively act like it was a FlexForm.

The ViewHelper render method does this, which seems to not be able to fetch settings from EXTBASEPLUGIN:

        $pageUid = $this->arguments['pageUid'] ?? null;
        if ($pageUid === null && !empty($this->getTypoScriptConfiguration()->getSearchTargetPage())) {
            $pageUid = $this->getTypoScriptConfiguration()->getSearchTargetPage();
        }
        $pageUid = (int)$pageUid;

@snk-spo Thanks for reporting that issue. Please provide infos about versions-stack.

@dkd-kaehm Sorry, forgot, I am running TYPO3 12.4.22 with Solr 12.0.5 on PHP 8.3

Ah, I found the issue. It's a little bit unintuitive however. It works when removing the settings scope, like this:

lib {
  searchBar = EXTBASEPLUGIN
  searchBar {
    extensionName = Solr
    pluginName = pi_search
    search {
      targetPage = {$pages.search}
    }
  }
}

ext:solr does not have its Extbase plugin configuration stored under settings, of course (instead it just has a custom array of configurations on the plugin root level). The core documentation of EXTBASEPLUGIN is very sparse about the allowed configuration that can be passed with it (so I intuitively assumed it would be settings, because in Extbase bascially everything is either settings, view or persistence), and ext:solr has no example at all in its documentation, either, about how to insert the search bar other than as a regular CE.

So this is rather an issue about incomplete documentation on both ends, TYPO3 and ext:solr.

@snk-spo Thanks for clarification. On which places of our docs did you expect a hints about that? Could you add it via pull-request?
