Adding new or editing existing marker resets the map center latitude and longitude expression

Issue:

We are using a map component from the 'Basic Elements' palette and have set the latitude and longitude values for the map center (under Map tab) to reference fields as $F{lat} and $F{long} respectively. 

However, when navigating to the Markers tab and adding a new marker or editing an existing marker, the map center latitude and longitude expression values were reset to 45.439722 and 12.331944 overwriting what was defined.

Solution:

This was reported as a defect (reference JSS-2682) and the workaround is to define all your markers first and then set/re-set the map center expression values last or copy and paste the relevant two lines back into the source code under the Source tab:

<c:latitudeExpression><![CDATA[$F{lat}]]></c:latitudeExpression> 
<c:longitudeExpression><![CDATA[$F{long}]]></c:longitudeExpression>
