pages widget not compatible with elgg 2.2.x

[oseg]

There is a database exception in views/default/widgets/pages/content.php when calling:
$widget->eligo_subtype = array('page_top', 'page');
It seems the database does not like the array...

I workaround the issue

by replacing:
$widget->eligo_subtype = array('page_top', 'page');
by
$widget->eligo_subtype = 'pages';
in both files views/default/widgets/pages/content.php & views/default/widgets/pages/edit.php

and by replacing

		if (is_array($widget->eligo_subtype)) {
			$options['subtypes'] = $widget->eligo_subtype;

by

		if ($widget->eligo_subtype === 'pages') {
			$options['subtypes'] = array('page_top', 'page');

in both eligo_get_display_entities_options() and eligo_get_selected_entities_options() functions in lib/functions.php

But what about the migration from an elgg v1.12.x to an elgg v2.2.x website ???
