Template

With EXT:maps2 version 10.0.0 we have remove PoiCollection- and EditPoiCollection ViewHelper. This part will explain how to change your template to use the new implementation.

PoiCollection

Add static TS template Maps2 Default (maps2) and one of the Maps2 for Google Maps (maps2) or Maps2 for Open Street Map (maps2) templates to the page where your extension/plugin belongs to, as far as not already done in root page.

In case of `Maps2 for Google Maps (maps2)`please check, if following TS constant is set:

plugin.tx_maps2.view.googleMapsJavaScriptApiKey

Add a further entry for maps2 to partialRootPaths configuration of your extension, so that fluid can find our new partials:

plugin.tx_myext.view.partialRootPaths {
    0 = EXT:my_ext/Resources/Private/Partials/
    1 = EXT:maps2/Resources/Private/Partials/
}

Replace old maps2:widget.poiCollection ViewHelper in templates of your extension:

<maps2:widget.poiCollection poiCollection="{location.txMaps2Uid}" override="{settings: {mapWidth: '100%', mapHeight: '300', zoom: '14'}}" />

with following html:

<f:render partial="Maps2/PoiCollection"
          section="showMap"
          arguments="{poiCollection: location.txMaps2Uid, override: {settings: {mapWidth: '100%', mapHeight: '300', zoom: '14'}}}" />

EditPoiCollection

Add static TS template Maps2 Default (maps2) and one of the Maps2 for Google Maps (maps2) or Maps2 for Open Street Map (maps2) templates to the page where your extension/plugin belongs to, as far as not already done in root page.

In case of `Maps2 for Google Maps (maps2)`please check, if following TS constant is set:

plugin.tx_maps2.view.googleMapsJavaScriptApiKey

Add a further entry for maps2 to partialRootPaths configuration of your extension, so that fluid can find our new partials:

plugin.tx_myext.view.partialRootPaths {
    0 = EXT:my_ext/Resources/Private/Partials/
    1 = EXT:maps2/Resources/Private/Partials/
}

Replace old maps2:widget.editPoiCollection ViewHelper in templates of your extension:

<maps2:widget.editPoi property="txMaps2Uid"
                      title="{company.company}"
                      poiCollection="{company.txMaps2Uid}"
                      override="{settings: {mapWidth: '100%', mapHeight: '300'}}" />

with following html:

<f:render partial="Maps2/EditPoiCollection"
          section="editMap"
          arguments="{poiCollection: company.txMaps2Uid, property: 'txMaps2Uid', title: company.company, override: {settings: {mapWidth: '100%', mapHeight: '300', zoom: '14'}}}" />
