Duplicate map detected!

Any idea how to solve this duplicate error ?

Any progress on this error? I get this error message in D5.

Subscribing.

I had to deactivate nodewords to get my map to display.

Yes I have the same problem, when I turn off nodeword everything works.
Is there any soloution to solve this problem, without turning off nodewords module?

Drupal 6.14

Same problem here! Only with a different module - Page Title 6.x-2.2

Posted a new issue : http://drupal.org/node/604484

Page Title and Nodewords modules are important for SEO. It's really difficult to make a choice between having a search engine friendly website or working Google Maps. Can someone please take a look at this issue?

Trackfield module got it too.

CorpX,
Thank you for posting this. Unfortunately, my PHP skills do not allow me to try your solution. Hope it works for someone else. Will keep waiting for a new Gmap version, hopefully it is not far away (the last time I checked they rolled back to v.1.0).

Greetings: not sure where the problem is coming from, but it just popped up for me when I installed and ran the first linkchecker (http://drupal.org/project/linkchecker) scan on a D6.15 site:

Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: nodemap

The site does make extensive use of GMaps, but I'm not sure what the reference to "nodemap" actually means.

You might often want a Gmap on the same node as a URL which uses the Link module: http://drupal.org/project/link (like a "Contact" page!).

The trouble is, if a Link field is present you get this Duplicate Map error again. So it's quite a problem.

Going by the multiple reports it certainly does seem to lie with Gmap rather than with other modules...

Subscribing, having the same..

EDIT: Working solution is adding

.$node->nid 

to the Gmap ID as stated above!
greetings, Martijn

subscribing, having the same using trackfield module (not using page title or nodewords by the way).

I don't see anything wrong with the code in the trackfield module:

...
          /* Default is gmap embedded */
          $path = sprintf(' |line=#%s/%d/%d:%s', $path_colour, $path_width, $path_opacity, join(' + ', $line_points));
          $gmap = sprintf('[gmap zoom=%d |center=%s |width=%dpx |height=%dpx |id=%s %s%s%s]',
            $zoom,
            $map_centre,
            $gmap_width, $gmap_height,
            "trackfield_map_" . $node->nid . "_$formatter",
            $trackfield_map_format_sizes[$formatter]['gmap_attr'],
            $path,
            $markers);

          _gmap_doheader();
          $out .= gmap_filter('process', 0, 1, $gmap);
...

Also tried the latest -dev of gmap, same results.

I faced this problem to. What I have is a node and in it you can reference various nodes containing a Gmap. If you reference twice the same node, it appears the error

Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: 53

I am using a template to draw the nodes that contains a Gmap and debbuging the code I saw the problem is taht when calling to ther function to get the map, you have to pass a parameter as the map ID, so if you use the node ID it will be duplicated.

To fix it, I have used PHP rand() function to get a random ID to generate the map:

Code needed in node-CT.tpl.php is:

    <?php
      $rand = rand(); 
    ?>
    <div class="entry-<?php print $rand?>-<?php if ($sticky) { print " sticky"; } ?>" style="float : left; padding-right: 1.5em;">
      <div class="ct-map-content"><?php print $node->content['body']['#value'] ?></div>
    
        <?php
          # Call Map Function
          # I have separated the parameters so that it easier to see
          print node_map_maker(
            $rand, 'small red'
            ,$node->locations[0]['latitude']
            ,$node->locations[0]['longitude']
            ,16
            ,'300px'
            ,'200px'
            ,'Small'
            ,'Map: Standard Street Map.'
          ) ?>
    </div>

Code needed in template.php:

#function to make Gmap macro data into a map
function node_map_maker($id, $mark, $lat, $long, $zoom, $width, $height, $control, $map_type) {
  #intialize output
  $output = '';
   
  #put together array
  $arr_map = array(
        'id' => $id
  ,'zoom' => $zoom
  ,'width' => $width
  ,'height' => $height
  ,'latitude' => $lat
  ,'longitude'=> $long
  ,'maptype' => $map_type
  ,'controltype' => $control
  ,'markers' => array(
  array(
                'markername' => $mark
  ,'latitude' => $lat
  ,'longitude' => $long
  )
  )
  );

  #display map through GMap theme function
  $output = theme('gmap', array('#settings' => $arr_map));
   
  #return output
  return $output;
} #end function

Anyone figured this one out yet?

I'm using trackfield with no problems, but get this error when i add a cck link.

Tried giving different id's to node and teaser versions in node-CT.tpl,php (see #9 above), but that didn't work.

Tried latest dev version, but that didn't work

Surely someone is using gmap and links on the same node - so how'd you do it?

Having the same issue with a custom module I wrote. This is really weird. I get the error 5 times:

Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: gmap-1897-a7c37d8c590f903b4b30185fe7e3cd56

Here's part of the code

function theme_venued_events_map($node) 
{
	$output = '';
	if ($parents = venued_events_get_parent_nid($node->nid)) {
		$output .= '<div class="field field-field-location">'. 
			venued_events_get_map_output($parents[0]->nid, $options = array('width' => '400px', 'height' => '350px')) . 
			'</div>';
	} else {
		$output .= '<div class="field field-field-location">'.
			$node->field_location[0]['view'].
			'</div>';
	} //endif;

	return $output;
}

If I comment out the function call to venued_events_get_map_output the error goes away. The really weird thing that's not event the code segment being executed on the page. The page is executing the else portion. This makes me insane.

Here's the code that makes the map

function _venued_events_get_node_map($node, $options = null) 
{
	$marker_popup = "";
  $places_gmap_setting = array(
      'id' => 'gmap-' . $node->nid . "-" . md5($_SERVER["REQUEST_URI"]),
      'type' => 'Map',
      'maptype' => 'Hybrid',
      'controltype' => 'Small',
      'width' => (isset($options['width']) ? $options['width'] : '450px'),
      'height' => (isset($options['height']) ? $options['height'] : '400px'),
      'zoom' => '17',
      'latitude' => $node->field_location[0]['latitude'],
      'longitude' => $node->field_location[0]['longitude']
	);
  $marker_popup .= '<div class="point-title">' . $node->title . '</div>';
  if (module_exists('image_attach')) {
    $marker_popup .= $node->content['image_attach']['#value'];
  }    
  $marker = array(
    'text' => $marker_popup,
    'markername' => 'blue',
    'autoclick' => true,
    'longitude' => ($node->field_location[0]['longitude']),
    'latitude' => ($node->field_location[0]['latitude'])
  ); 
	$places_gmap_setting['markers'][] = $marker;
	$output = theme('gmap', array('#map' => 'venued_events_map', '#settings' => $places_gmap_setting));
  return $output; 
}

Guys!!! Awesome! I think i find the solution (or maybe just one of the solutions).

In settings of block of Location there is "Map Macro" field (see screenshot).
There is id=usermap setting.

Need to DELETE this.

WRONG:
[gmap |id=usermap|center=40,0|control=none|zoom=12|width=100%|height=300px]

NEED:
[gmap |center=40,0|control=none|zoom=12|width=100%|height=300px]

I think in this case id will generated automaticaly and all is ok.

Found the same solution as #20, but I was using an attachment and cck location.
Delete id from the macro in Attachment>Style:GMap>Macro

I'm still getting this error message on my site, and I checked the set-up from #20 and that doesn't seem to be the issue, as id=usermap is not there. Instead, it reads

[gmap |width=100% |height=200px |control=None |behavior=+autozoom +notype]

My exact error message reads:
Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: trackfield_map_145_default

Any suggestions on how to resolve this error from coming up?

At the very least, I would like the error to stop showing up for users on their page. I have write errors to screen turned off, but the "Duplicate map detected" is still showing up on the screen periodically for anonymous user.

My exact error message reads:

"Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: trackfield_map_151"

solution #20 seemed to work for me ... I had two GMAPS on one page ... and removed both id's in Site Configuration > Gmap Location > ...

#20 also does it for views in 7.x. I had been using unique id's for the map views I was creating and was getting the same error when the views were embedded in nodes and the nodes displayed on teaser lists.

Removing the id= part of the macro fixed it and it had no other impact on displaying the maps (I'm only doing one map per page though, so I haven't tested if multiple maps will fail).

#20 also worked for me! Thanks for the tip. I think the problem at my site has started by activiting the fusion starter theme

In my case, I had to remove the id from a custom made view, but #20 works nevertheless.

#20 did not solve my problem. I'm still getting the error message consistently on my site. At the very least, I would like a way to hide this message from anonymous users, because it shows for them too.

This seems to work.

$id = rand(0, 1000000);
$map_array = array(
    'id' => "my-map".$id,
...

I get "Duplicate map detected! GMap does not support multiplexing maps onto one MapID! GMap MapID: nodemap" when I have a map showing all the nodes on the frontpage.

This happens ONLY when I have NOT logged in AND the "language" parameter is set in the url.

I have only created block to show the map

$block = array(
      'subject' => t('Map'),
      'content' => gmap_location_node_page(),
    );

No solution has yet been found...

@brisath for drupal 7 go to admin/config, than chose error reporting and select the options to not show any errors ;-).

#9 worked for me! Custom template node-yourtypehere.tpl.php and the code mentioned in #9 that adds the nid to the id to keep it unique.
