Views OpenLayers generated map is empty [#1325446]

I have OpenLayers and Geofield installed.

My goal is to have 2 pages.
First - node edit, where user can input his location using Geofield with Openlayers Map widget. This works fine.
Second - custom Views using OpenLayers, showing some nodes in map based on some filters(doesn't work).

The problem is in empty map, views shows map but empty. Views for OpenLayers are created and configured step by step using documentation (before this I had successful openlayers configurations). I'm trying to find possible problem for hours.

After issuing this problem i have created simple lat and long float fields and modified views to use that fields. Again, no luck.

OpenLayers Data Overlay renders the following

You can use the following parameters in your styles as dynamic values
------------
${field_lati_rendered}
${field_lati}
${field_longti_rendered}
${field_longti}

------------
The following is a dump of the data that is rendered from this display. It is used for debugging purposes only.
        array (
  0 => 
  array (
    'projection' => '4326',
    'attributes' => 
    array (
      'field_lati_rendered' => '41.0000000000',
      'field_lati' => '41.0000000000',
      'field_longti_rendered' => '42.0000000000',
      'field_longti' => '42.0000000000',
    ),
    'wkt' => 'POINT(42.0000000000 41.0000000000)',
  ),
)

So, this looks OK, it seems that this Display sends correct information.

I have also dumped dprint_r($this->view) in openlayers_views_style_map.inc file's render() function. I tried basic search using browser to find '42.000' coordinate. So I don't found. I'm not familiar with Views API. But I think it should be there.

Any ideas? What can cause problem like this? Anyway to debug?

Hi @Toktik. Are you using filters or arguments with your Views OpenLayers Data Overlay?

I'm having a similar problem where I'll create a page view, set up an openlayers map on it, then add the openlayers data overlay display which OVERWRITES my openlayers map page display, essentially trying to render the map itself as the datasource instead of lat/lon or wkt.

So, essentially I'm stuck with either Format: OpenLayers Map on both displays, or Format: OpenLayers Data Overlay on both displays.

Toktik commented 12 November 2011 at 06:10

@zzolo, I'm using argument.
@swombrother, it seems you are not overriding Format. See Views Override feature.

davycw commented 12 November 2011 at 20:08

I'm having trouble finding that feature. Where is it?

Comment #5

zzolo commented 26 November 2011 at 00:40

@davycw . I think your issue is different and it sounds like you are just not using Views correctly. Try creating a separate View for the Data Overlay, and one for the Map Display.

@Toktik. There could be many reasons why your map isnt showing up.

* Are you sure your argument is working correctly?
* Do you have styles correctly set?
* Can you export your map and paste here?

Hi,

I'm having the same issue here. I had a map set up properly using features, which was working with geofield alpha5 and openlayers alpha2, upgraded both modules and now everything is gone... It seems like the openlayers data overlay works correctly and that the map finds the right layers, but no point appears on the map...

I've had problems with my points too. Can you check your JS console ? there should be an error, please paste it here.

It would also be good if you export your map, and paste the code here as well.

@Admdebian - I marked #1460988: Views arguments problem? as a duplicate.

@Toktik - thanks for the views export. Would be useful to have more feature exports for OpenLayers that made it easier for people to set up & get going with this great module.

Ok, so to try to eliminate possible problems, I've tried the following & provided the following feature to help replicate it.

I set up a very basic node with a Geofield WKT input text. I added a POLYGON at a well known location to a piece of sample content I developed. I set up a OpenLayers Map (or in D6 'Preset') and did some minor customizations on that. Then I set up three block views:
1) a basic unformatted list with a Contextual Filter (or in D6 'Argument') for the node ID
2) a clone of that with the Geofield set so that the Formatter set to OpenLayers and the OpenLayers Preset set to Geofield Formatter Map.
3) a clone of that one which is trying to use OpenLayers and has an OpenLayers Map Overlay along side a block.

1 & 2 clearly indicate that they are tied to the node which is being loaded.
I get a map on both 2 & 3, but only see the polygon on 2

Hopefully this feature makes it easier for someone else to figure out what I'm doing wrong. I can't just lean on the Geofield Formatter map as I can't use the Google Maps, but need to select a different set of images to work with.

Comment #13

nerdcore commented 15 March 2012 at 21:49

I have created an OpenLayers Data Overlay in Views which is capable of extracting WKT Geofield data from a node and making it available to an OpenLayers Map which has the Data Overlay enabled and activated. This Data Overlay has a contextual filter of Content:Nid so that I can display a single node's WKT POLYGON on a map accompanying the node.

This works fine and can be demonstrated by typing in a node ID into the "preview with contextual filters" option of the View setup. Previewing in this way on the Data Overlay returns the node title, and Geofield WKT POLYGON as expected.

I am hoping to display the map using a Block, so that it can be added to a specific content type. This produces one startling failure when previewing with contextual filters:

Setting the Block to a format of "Unformatted List" results in the preview showing the WKT data as expected (for example "POLYGON ((30 10, 10 20, 20 40, 40 40, 30 10))")
Setting the Block to a format of "OpenLayers Map" with the map that is associated to the Data Overlay results in an OpenLayers map with no POLYGON.

So, why does the block know about the WKT field (as demonstrated in an Unformatted List), but fail to render the WKT data as an OpenLayers Map?

Hi. I'm experiencing a similar problem and while I haven't been able to completely resolve my issue I hope that my discoveries may assist others.

To recap: I'm seeking to create a dynamic map using OpenLayers, Drupal 7, Views and a Custom Content Type. So far I've been able to:

successfully create a content type (using "Geolocation Field" to store geodata),
create an OpenLayers Overlay in Views (which seems to accurately render the textual overlay data), and
create a custom map (clone of Google Map example) in OpenLayers Admin.

In OpenLayers Admin I can view the sample map ('MySample Map" - a clone of the GoogleMap example) under OpenLayers Admin: Maps: Edit Map: Preview where it successfully shows data points from content in the database. However when I create a new separate View of format = OpenLayer with style = "MySample Map" almost nothing shows under Views Preview: no datapoints and no map, only the title. Visiting the resulting Views page exhibits the same.

Another poster ( @Toktik ) was also using "Geolocation Field" instead of GeoField. I discovered that in order to get Geolocation Field to minimally work I needed to add the content type's Geolocation Field twice, the first formatted as Latitude data and the second formatted as Longitude data. Then I selected Views Format: Settings and under OpenLayers Data Overlay: Style Options I configured Map Data Sources for Lat/Lon Pair and Latitude Field and Longitude Field to reference their respective fields. I was never able to get WKT to work. For more info see http://drupal.org/node/1469524.

So while I can see the map under OpenLayers Admin I am still unable to produce a usable View. Any recommendations for debugging/resolving this problem? If it could assist anyone I've attached exports of the Views Overlay, the Map Location View, and the OpenLayers Map definition. Thanks in advance.

This was because I didn't have my map's OpenLayers Data Overlay enabled and active on the layer settings for my map.
