Not really clear on what you’re trying to do, but try looking at one of the following approaches:
1) use a “computed for display” field to display the value of the field you’re interested in –
So, you’d have a field called dspFld1 (for example) and the formula for it could be @GetField( “Salary” )
Or, it could be @GetField( VariableThatContainsStringNamingAnotherField )
2) use “computed text” to do the same thing as above.
If things don’t seem to update properly (or dynamically enough) for you, you may need to add @Command([ViewRefreshFields]) to the code behind your button(s).
