[mapguide-internals] Does the Select Within only work for polygon

[Dave Wilson]

SelectWithin is a replication of functionality that existed in MG 6.5. The only documentation is from the 6.5 help which isn't entirely accurate because we didn't replicate the full functionality.

The basic premise is: the user selects one or more polygons (and/or buffers) and wants to find objects "within" those polygons. The current implementation uses an intersection if I am not mistaken so any feature that intersects the polygon should be selected.

I logged 2 defects previously 1223510 and 1223511 regarding the fact that a "within" select (meaning only inside) actually uses intersects which is a bit of a contradiction.

In MG 6.5 we had options for Select Within including selecting objects whose centroid was within the polygon. We never replicated the centroid functionality.

Hopefully that makes things clearer.

Hi Dave,

Do we have any specs or something to describe the SelectWithin feature?

Thanks,
-Buddy

SelectWithin should work with a polygon or multi-polygon. Whether or not the logic is clean enough to handle a case where more than one type of feature is selected (a polygon and a line for example) is another question.

The 500 error is a bug for sure.

Regards,
Dave

Thanks Kenneth!
I think so. It seems that there are some logic error for the selectwithin.php.
Any other comments?

It sounds a like a bug to me.
At least there should not be a "500" error.

If there are some other features (such as multipolygon, polyline) selected with polygon, there will be a 500 internal Server Error for selectwithin.php. If there are only multipolygon selected, everything will be cleared after I press the "Done" button.
