<div dir="ltr">Thanks everyone for your suggestions. Based on the feedback, we identified the issue being Nulls in a Date formatted field in the database table.

I suspect that it is because it is a numeric value that contains null, and there is a bug in the function that returns value in MapGuide that causes null value to give an error. Is there probably information about this in the log file for MapGuide? Kind regards,
Dan</div>

We're experiencing an issue where random items on the map won't select, even though the layer is set to be selectable. I've been unable to identify a common setting between the various layers that are experiencing this issue.<span></span></p>
<p style="margin:0cm 0cm 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">
In the below image, the outermost lines are selectable (labelled as “S”), however the inner ones are not selectable (labelled as “NS”), unless you also select one of the outer lines. We're getting similar behaviour in other layers that correspond to different
tables.<span></span></p>
<p style="margin:0cm 0cm 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">
Has anyone else encountered this issue? We're using MGOS 4 Final Release. We don’t encounter this issue in an environment that’s set up with MGOS 4 Beta 2, reading from the same database. Additionally, I'm not noticing any entries in the error logs that would point
to the issue.</p>
