Hello,

I recently posted a comment about my question in https://drupal.org/node/1343482#comment-8147741 .

I want to expose a filter in a view, that is text list field and allow the user to choose what value he wants.

The text list field is like this :

1|name_1
2|name_2

When the view is displayed, it appears a drop down menu for this filter with options:

select all
name_1
name_2

By default, when I first edit the view and add this filter, it shows the error message "No valid values found on filter:..", having "select all" as chosen value (I suppose). There was one time, that I could save the view (now the system does not let me do this) and see it then as an anonymous user, when another error was displayed : some parameters are not well defined by the administrator.

But then, if I press the submit button (having again the "select all" as choice), it works fine.

I checked "Always show the master display" in views settings, as I saw that it's usefull, but I do not wish to delete this filter, because my client needs it in the view.

Is there a possibility that the function that displays the results in the view, receives as a parameter an empty string for field value ? I wish to select the "select all" option, in order to have all the instances displayed at the begging and filter some of them later.

Thank you very much,
