Library Save to Copy does not copy folders accurately #1003

Steps to reproduce the issue

  1. Start with a relatively fresh install of JCB. I have my one component I'm working with.
  2. Create a library pointing to a folder. The id of my library is 7, since there are 6 previous libraries existing in JCB.
  3. Add a folder to the new library, which of course points to ADMIN/com_componentbuilder/custom/myfolder. Save this new library, test it and see that it compiles into the component properly.
  4. Edit the new library, and click the Save As Copy button.
  5. See that the new library is saved, but the Files, Folders & URLs tab contains data from one or more of the previous libraries that come with JCB, not from the library with id = 7.

Expected result

Save As Copy function should copy all the for data correctly.

Actual result

As described above.

Additional comments

I can do a record dump of the tables

#__componentbuilder_library
#__componentbuilder_library_files_folders_urls

which I think might be the most useful. You can see that in the newest #__componentbuilder_library_files_folders_urls record, the library field actually points to the wrong record in #__componentbuilder_library. I've traced the code but I've been unable to see where the mixup occurs.

This is currently the code we are looking at:

// get the state object (Joomla\CMS\Object\CMSObject)
$state = $model->get('state');
// if we save2copy we need to also copy linked tables found!
if ($state->task === 'save2copy' && $state->{'library.new'})
{
	// get new ID
	$newID = $state->{'library.id'};
	// get old ID
	$oldID = $this->input->get('id', 0, 'INT');
	// linked tables to update
	$_tablesArray = array(
		'library_config',
		'library_files_folders_urls'
	);
	foreach($_tablesArray as $_updateTable)
	{
		// get the linked ID
		if ($_value = [[[Component]]]Helper::getVar($_updateTable, $oldID, 'library', 'id'))
		{
			// copy fields to new linked table
			[[[Component]]]Helper::copyItem(/*id->*/ $_value, /*table->*/ $_updateTable, /*change->*/ array('library' => $newID));
		}
	}
}

Which is converted to:

// get the state object (Joomla\CMS\Object\CMSObject)
$state = $model->get('state');
// if we save2copy we need to also copy linked tables found!
if ($state->task === 'save2copy' && $state->{'library.new'})
{
	// get new ID
	$newID = $state->{'library.id'};
	// get old ID
	$oldID = $this->input->get('id', 0, 'INT');
	// linked tables to update
	$_tablesArray = array(
		'library_config',
		'library_files_folders_urls'
	);
	foreach($_tablesArray as $_updateTable)
	{
		// get the linked ID
		if ($_value = ComponentbuilderHelper::getVar($_updateTable, $oldID, 'library', 'id'))
		{
			// copy fields to new linked table
			ComponentbuilderHelper::copyItem(/*id->*/ $_value, /*table->*/ $_updateTable, /*change->*/ array('library' => $newID));
		}
	}
}

If you can see where my logic is breaking down... we can add a fix.

The copyItem code is found here.
