Possible bug in geodir_listing_permalink_structure()

This could be my bug, but I’m confused about what’s happening.

I have a client using my GT Vouchers plugin and in one of the widgets, I show the most recent vouchers and link to them. On his site, the links come back NULL when I call get_post_permalink( $voucher_post->ID );

I traced this and get_post_permalink runs your filter geodir_listing_permalink_structure and this is where the NULL comes from. My link is passed in, the post information is there etc. The code I don’t quite get is this (line 1028) but I cleaned it up to post here:

	if ( isset( $post_obj->ID ) && isset( $post->ID ) && $post_obj->ID == $post->ID ) {
	} elseif ( isset( $post_obj->post_status ) && $post_obj->post_status == 'auto-draft' ) {
		return $post_link;
	} else {
		$orig_post = $post;
		$post      = $post_obj;
	}

I’ve debugged this and we’re hitting the third condition – the ELSE. My $post_obj coming in has an ID of 321, but the current post – for some reason – is 128, the don’t match and so the posts get swapped. Which is fine, but confusing.

Then we get to 1054:

		if ( isset( $gd_permalink_cache[ $post->ID ] ) && $gd_permalink_cache[ $post->ID ] ) {
			if ( isset( $orig_post ) ) {
				$post = $orig_post;
			}

			return $gd_permalink_cache[ $post->ID ];
		}

The code checks if the cache exists for $post->ID (which is 321 coming from my $post_obj) and if it is set checks if we have an $orig_post and then returns THAT link instead, which is obviously not going to be the link that I asked for.

Any thoughts on WHY this is and how I should handle this? Maybe because I am in a widget and don’t setup the full global $post object? but I’m not sure why GeoDirectory is overriding that…
