Hello,

I have the following code:

\<%= select\_tag :role, options\_for\_select(Project::COMPANY\_ROLES.concat  
([‘Other…’]), @relationship.role), :class =\> ‘selectInput  
hasOtherValue’ %\>

For some reason it concatenates “Other…” to COMPANY\_ROLES but saves  
this past the view that was loaded.

1st Run = 1 option of “Other…”  
2nd Run = 2 options of “Other…”  
3rd Run = 3 options of “Other…”

I simply want it to concatenate during run-time and not save state.

Any ideas?

Thanks!

This does the trick:

\<%= select\_tag :role, options\_for\_select(Project::COMPANY\_ROLES +  
[‘Other…’], @relationship.role), :class =\> ‘selectInput  
hasOtherValue’ %\>
