I have faced serious difficulties while installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4 w/ Doctrine ORM. The installation directly from the server did not work out like with previous plugins that I have installed:

C:\path>symfony plugin:install sfJqueryTreeDoctrineManagerPlugin
plugin installing plugin "sfJqueryTreeDoctrineManagerPlugin"

No release available for plugin "sfJqueryTreeDoctrineManagerPlugin"

This is why I needed to install the plugin by downloading the tgz-archive and install it manually like this:

C:\path>symfony plugin:install "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz"
plugin installing plugin "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz"

sfSymfonyPluginManager Installing web data for plugin

I guess everything should be fine this far?

After that I edited \apps\admin\config\settings.yml like instructed in the plugins readme file.

all:
  .settings:
  enabled_modules:     [default, sfJqueryTreeDoctrineManager]

I also checked that the plugin was enabled in \config\ProjectConfiguration.class.php like this:

$this->enablePlugins(array(
  // other plugins,
  'sfJqueryTreeDoctrineManagerPlugin'
));

I published assets and cleared cache:

C:\path>symfony plugin:publish-assets
>> plugin Configuring plugin - sfJqueryTreeDoctrineManagerPlugin
C:\path>symfony cc

Finally I added the required helper to the newly created apps\admin\modules\category\templates\indexSuccess.php

<?php
use_helper("sfJqueryTreeDoctrine");
echo get_nested_set_manager("Category", "name");

When loading the page I unfortunately get the following error:

500 | Internal Server Error | InvalidArgumentException
Unable to load "sfJqueryTreeDoctrineHelper.php" helper in: SF_ROOT_DIR\apps\admin\modules/businessunitgroup/lib/helper, SF_ROOT_DIR\apps\admin\lib/helper, SF_ROOT_DIR\lib/helper, SF_SYMFONY_LIB_DIR/helper.

The file sfJqueryTreeDoctrineHelper.php exists indeed but not in any previously mentioned folder. The file can only be found in the folder \plugins\sfJqueryTreeDoctrineManagerPlugin\lib\helper. I guess that Symfony doesn't look to that folder while finding helpers?

I have tried to move the helper file to one of the previously mentioned folders. As expected, that changes the error. Now I get:

500 | Internal Server Error | sfConfigurationException
The component does not exist: "sfJqueryTreeDoctrineManager", "manager".

Unfortunately I can't figure out how should I be able to retrieve the "missing" component from the correct folder.

I would be very grateful for any advice to help me forward.

By the way, I am aware that there are other nested-set / tree plugins available for Symfony (like sfDoctrineTreePlugin and caPropelTreePlugin) but unluckily those are either uncompatible or too limited for my needs.
