[symfony-users] AW: [symfony-users] sfPropelActAsNestedSetBehaviorPlugin -- reload() required?

[Franke Gordon]

You must reload the object when you make something like that:

Make $root
Add $child1 to root
-----------------------
Add $child11 to $child1 (now you must reload the $child1 before add)
Add $child2 to root (now you must reload the root before add)
-----------------------

This may be the cause of similar problems I am having (incorrect left/right
values appearing after a while).

Tristan, is it true that a reload() is required after each
insertion/deletion into the tree? If so, is it the parent node, root node or
both that need to be reloaded?

...and, if so, shouldn't the Wiki & ReadMe documentation be updated to add
the reload() command after each child save() command (see below).

...or better yet, if this is required, why not add the root node reload
automatically in the plugin after any insert/delete/revision of nodes in a
given tree?

Updated documentation if reload() is required?

=== Simple tree creation ===

<?php
  $root = new ForumPost();
  $root->makeRoot();
  $root->save();

  $p1 = new ForumPost();
  $p1->insertAsFirstChildOf($root);
  $p1->save();
  $root->reload();

  $p2 = new ForumPost();
  $p2->insertAsFirstChildOf($p1);
  $p2->save();
  $root->reload();

  /*
   * Resulting tree :
   *
   * ROOT
   * |- P1
   *    |- P2
   */


=== Multiple trees in a single table ===

<?php
  $root1 = new ForumPost();
  $root1->makeRoot();
  $root1->setTopicId(1);
  $root1->save();

  $root2 = new ForumPost();
  $root2->makeRoot();
  $root2->setTopicId(2);
  $root2->save();

  $p1 = new ForumPost();
  $p1->insertAsFirstChildOf($root1);
  $p1->save();
  $root1->reload();

  $p2 = new ForumPost();
  $p2->insertAsFirstChildOf($root2);
  $p2->save();
  $root2->reload();
