If you already have a map based on the ReportMap plugin, you can if you wish convert it to a map by simply changing the region Type to Map – the SQL data source will be preserved and you can use the same query for the new Map region type.

The Map region is free to use within your applications, just like any other built-in feature of APEX. no API key, and no APIs need to be enabled.no account on a 3rd party cloud service.To add a map to a page, I added a region of type “Map” and nominated a data source for the Layer to show on it.įirst thing you might notice is what I didn’t need: Let’s try the new Map region, and compare it to the jk64 ReportMap plugin. The APEX Map region renders the map using the MapBox API, with a number of tile backgrounds included based on OpenStreetMap and HERE map data. There will be more official blog posts coming directly from the APEX development team about this and other new features being introduced in APEX 21.1, so keep a look out for those! Note: this post is based solely on my first impressions of the new feature and is not intended to answer all questions about it. It also means that maps added to applications based on the core feature will be fully supported in future releases of APEX without needing to rely on a 3rd party. due to the lack of direct support from Oracle). This is a welcome move because it means maps will be easy for all APEX developers to use, including those who avoid plugins (e.g. This component allows the developer to show a world map on the page, and add one or more “Layers”, each based on a table or SQL query, to show features on the map. In the latest pre-production release APEX 21.1 which you can try today for yourself at, the APEX development team has introduced the new Map region. The most popular of these is the ReportMap Plugin which has received a wealth of features and enhancements, and is being used widely. Since 2016 I have built and maintained plugins that make it easy to integrate Google Maps in your APEX applications. Within the APEX development team it has been known for some time that maps are frequently required and this has been on the roadmap to be built in to the core product. by putting a NOT NULL constraint on it), which would also have resolved this problem. Alternatively, I could have ensured that the underlying column would always have a value (e.g.

When I set Display Null Value to Yes, the problem was resolved. What was happening was that the item could not handle a null value, so it was changing to the first value in the LOV this in turn marked the item as “changed” which caused the “unsaved changes” warning to show when the user tries to navigate away from the page. I noticed that the item had a List of Values, and it had the Display Null Value setting set to No however, the value in the underlying column was NULL. This pointed me to a single item and I had a closer look at it.

I found Martin D’Souza’s article How to Find Which Item has Been Changed in APEX and ran the code in the browser console. I was wondering why the user always got an unexpected warning “Changes that you have made may not be saved.” – even though they hadn’t changed anything on the page. I had an APEX page based on a Form region that I’d built by hand (rather than using the wizard). I didn’t change anything… yet I get “Unsaved changes”?
