failed initialization of EPSG from address search

[SvenLVGL]

Describe the bug ¶

The map viewer throws error messages and does not work as intended when opened directly from the address search if it was not initialized before.

To Reproduce ¶

Steps to reproduce the behavior:

1. Close your browser.
2. Open your browser in a private window (no cache/cookies/etc.)
3. Go directly to the address search, without opening the map viewer before
4. Search a valid address and open the resulting link to view it on the mal
5. See error similar to the attached screenshots.

Expected behavior ¶

The map viewer should zoom to the addresses location on the map and display a dot to indicate the location.

Screenshots ¶

Desktop ¶

Has been tested with

• Google Chrome
• Mozilla Firefox
• Microsoft Internet Explorer
• Microsoft Edge

Additional context ¶

The fix seems to be found already. The issue is in the file mapbender/http/javascripts/initWmcObj.php.

The following line seems to produce the problem, if the epsg has not been initialized in this session before.

$currentEpsg = Mapbender::session()->get("epsg");

The solution could look like this:

$currentEpsg = Mapbender::session()->get("epsg");
        if (!$currentEpsg) {
            $currentEpsg = $DEFAULT_EPSG;
        }

With DEFAULT_EPSG being defined in a configuration file that's included.
