[Cartoweb-users] Problem creating new layers

[Nicolás Eugenio Ozimiça]

You're right!

Here is the code that tries to make visible a new layer (simulacionesGrupo):

    public function filterPostRequest(FilterRequestModifier $request) {
        $layerList = $request->getValue('layers');
        $layerList[] = 'simulacionesGrupo';
        $request->setValue('layers', $layerList);
        $this->tempinfo = implode('--', $layerList);
    }

it is in the Client part of a plugin that implements FilterProvider.

To create the layer:

    function initializeRequest($requ) {
        if ($requ) {
            $pluginManager = $this->serverContext->getPluginManager();

            if (empty($pluginManager->mapOverlay))
                throw new CartoserverException("mapOverlay plugin not
loaded, ");

            $mapOverlay = $pluginManager->mapOverlay;
            $layer = new LayerOverlay();
            $layer->name = "simulacionesGrupo";
            $layer->action = BasicOverlay::ACTION_INSERT;
            $layer->data = "raster/ozono.99.tif";
            $result = $mapOverlay->updateMap($layer);
        }
    }

it is in the Server part of the same plugin that extends
ClientResponderAdapter.

Anyway, if the "simulacionesGrupo" layer is defined in the mapfile, and the
line with ACTION_INSERT is not used in the last piece of code, and the next
line is commented in 'layers.ini':
; mapInfo.initialMapStates.default.layers.simulacionesGrupo.selected = true

it doesn't show up in the main map.
