Problem with actions "on activate"

Mon, 25 Jul 2011 08:26:02 GMT

Good day,

I want my application to have the following behavior:

- if in the "Field 1" there is only 1 value possible other than "other", select this value

- else select nothing

In my actions, I set :

- clear all

- Field1: =if(count(distinct if(Field1 <> 'other', Field1)) = 1, only(if(Field1 <> 'other', Field1)))

This should work.

BUT, when I activate the sheet with a previous selection, the "clear all" statement is not done first.

Exemple:

My data are the following :

LOAD * INLINE [
Field1, Field2
A, 1
B, 2
other, 1000
];

If I have a previous selection in "Field2" with only 1 element, the result of the actions "on activate" is that 1 value is selected whereas none should be selected.

It is like if the "count" function was done before the "clear all" action.

A solution is to use the following formula :

=if(count({1} distinct if(Field1 <> 'other', Field1)) = 1, only({1} if(Field1 <> 'other', Field1)))

but I think that the fact the actions are not done in the correct order is a bug.

HI,

Please have a look at the example attached here with.

Hope this is what you want.

Delete 1 value from the field and reload it again and check.

If I have only "A" and "other", I select "other", I go to the sheet --> nothing is selected.

The usage of "invert selection" is quite counterintuitive

I have a solution using

=if(count({1} distinct if(Field1 <> 'other', Field1)) = 1, only({1} if(Field1 <> 'other', Field1)))

but I'd like to know why "clear all" is not done first.

How can I suggest a bug ?

Hi,

Actually it did, but then you had the if statement, i think that didnt work.

Good day Luis,

Unfortunately, I don't understand what your application shows.

Do you say that, for you, the selection of "B" doesn't affect the :

- CLEAR ALL

- Field1 = if(count(distinct if(Field1 <> 'other', Field1)) = 1, only(if(Field1 <> 'other', Field1)))

Hi Nicolas,

For me when you select a unique value in Field2 in tab 1 (in Field1 only is possible a value), then when pass to tab 2 (with option Set Anz $), automatic deselect value in Field2 (Clear All), after by Select in Field for Field1 is select a only value¡¡, then for me all ok.

Good luck, Luis.

I go to the first sheet and make sure 1 value is selected:

Next step, I click on the second sheet.

What I expect is :

- CLEAR ALL --> nothing is selected

- =if(count(distinct if(Field1 <> 'other', Field1)) = 1, only(if(Field1 <> 'other', Field1))) --> there is 4 values different than "other" if "Field1", so, I should select nothing in "Field1"

What I have is:

A value is selected in "Field1", and it's wrong.

I suppose that the "clear all" is not taken into account when my formula "if(count(distinct if(Field1 <> 'other', Field1)) = 1, only(if(Field1 <> 'other', Field1)))" is calculated, whereas the "clear all" is the very first action.

I tried with QV 9 SR7 and QV 10 SR2.

Wich version do you use ?
