Code only works in debug mode

[BrianBulla]

Hi,

I have some code I'm trying to troubleshoot.  It does some editing of attributes to a point and the intersecting line feature.  A user can select multiple points, and then click the tool to run the code on each selected point.  I get no error messages, but the results are not as expected when selecting more than one feature.

The weird thing is that if I step through the code, line by line, everything works fine.  The only time I have problems is when running the code in real-time.  For some reason, only the first feature selected gets updated, and all the other features keep their original attributes.

I will post the code below, but here is the main logic behind it:

1.  select one or more hydrant features and click on the tool

2.  the tool work through each selected hydrant one at a time

3.  it finds the intersecting water service connected to the hydrant and updates the SUBTYPE attribute of the water service

4.  it then finds the intersecting water main of the water service, and updates the WATERMAINSIZE and WATERMAINID on the hydrant feature

5.  goes to the next selected hydrant and repeats steps 2 through 4

If anyone has any ideas as to why this code will not work in real-time, please let me know.

Thanks!

OK, I think I have figured it out.  I have moved my

var insp = new ArcGIS.Desktop.Editing.Attributes.Inspector();

to before the foreach loop, and now all is working as expected.  I'm still not really sure why it worked in debug mode before, but it seems to be working now in real-time and debug mode now.

Thanks!!
