Here's a minimal example:

DynamicModule[{var = "", searchlist, randobutton},
 searchlist = 
  Table[StringJoin[RandomSample[CharacterRange["a", "z"], 7]], 40];
 randobutton = 
   var = StringJoin[RandomSample[CharacterRange["a", "z"], 2]]];
 Deploy@Panel[#, ImageSize -> {Automatic, 300}] &@
        Column[{Dynamic[var, TrackedSymbols :> {var}],
                PopupWindow[Button["pop", Nothing], randobutton],
                InputField[Dynamic[var, TrackedSymbols :> {var}], String, 
                        ContinuousAction -> True],
                Dynamic@Column[If[var === "",
                                Select[searchlist, StringContainsQ[var]]]]
                }, Center]

If you press the main button, the InputField's string updates. If you press the popup's button, this does not occur. If the Dynamic[var] outside of the InputField did not have the TrackedSymbols option specified, it would exhibit the same behavior as the InputField, but the same fix does not work for the InputField.

How do I fix this bug?

Thank you very much for the help.

  • $\begingroup$ So, I replaced PopupWindow for CreateDialog[ __ ] which works on the front end. Thanks! @Kuba I'm curious why the TrackedSymbols change worked for the Dynamic[] but not the InputField[]. $\endgroup$

PopupWindow is the wrong function. You can use CreateDialog instead.

Here's an updated version:

                    DynamicModule[{}, randobutton, InheritScope -> True]]],
            InputField[Dynamic[var], ...],
