condition not working

[willy30870]

Hello again ,

I have a new mistake with conditionnal step that are in a "apply to each" loop : 

she is still true so she should not.

my condition : 

not(empty(outputs('Compose_2')))    is egual to  true (expression)

I want to know if the compose 2 output is empty or not

but I have always the same result whereas the output compose_2 switch well...

If someone have an idea...thank you!

Hi @willy30870 ,

Thanks for the screenshot. 

I did tested this and I got the expected results.

Find the length of the compose output using the below expression.

length(outputs('Compose_2'))

You must have a blank value returning.

Let me know the results.

Hi @willy30870 

Thanks for the quick response.

What I meant is find the length of the compose output in a variable. If it's more than zero that means there is something in the compose output.

It's working, I find it a little complicated but it works.

in case :
I have a table of data with a "select" step and 2 columns. I want to hide column 2 when it's empty.
if there is another solution than the one above I am interested!

Hi @willy30870 ,

The reason for this result is that the value in Compose is actually space, so the result of the condition is not empty.

Although there is no specific value, it will still be treated as a character, so the result is always true.

Based on this situation, you could use the length() function to determine the number of characters directly in Condition. If it is equal to 1, it implies that the value here maybe just space and there is no actual value.

Expression reference:

length(outputs('Compose'))
