Jill wins the award for unearthing an obscure ERMA bug with columns named "id."
You can try it for yourself!
- Find a favorite ERMA layer that has an "id" column.
- Use the identify tool to click on a feature
- Notice that the value in the id column is a really long number.
- Click on the same feature again
- Notice that the value in the id column is a similar, but different really long number.
Wha?!!!! Wacky stuff.
This is because in MapServer template files, "id" is used as a special word to display a session id which includes a unix time stamp.
See http://mapserver.org/mapfile/template.html#general if you want techie details
This issue does not affect the actual data themselves or the downloads, just the display with the Identify tool
So....until this bug is fixed in ERMA, if your id column is something that contains data of interest to the end users (rather than some arbitrary value that is not needed), use a different column name for that column.
