   I'd like to take a look at this. Could you download the CDI XML file with e.g. the Memory Tool in the latest JMRI version and then attach it here? Thanks.

   We are aware of this issue, but it's not clear to us what the fix would be. The CDI has a dropdown (combo box) with a certain discrete set of mapvalues. The standard functions F0 to F28 are not part of this list. This makes the dropdown menu unable to match the field's value (8) to anything in the list. To make things funnier, we actually have two fields in the CDI pointing to the same memory location. We did this with a negative offset attribute. One field has the drop-down, the other is a pure integer. I don't think this is an essential part of the repro case though, but explains why values that are not found in the map are meaningful to the product.

   There are some DecoderPro decoder definitions that do similar things (if I'm understanding correctly). DP manages this by adding a "Reserved value NN" item to the JComboBox when an unexpected value NN is encountered. That's a transient addition, so doesn't show up if just the listed values are being used.

   Would that be a suitable solution here?

   I think this is now fixed along the lines of how DecoderPro does it (see above). If the 2nd field is set to e.g. 27, the first field will get a new entry in the combobox: "Reserved Value: 27" which is shown as selected. Does that let us close this issue?
