Bug report: Logic with blank/null value

Here is how to reproduce the issue:


1) Create a text input, TextInput1 and clear its content to leave it blank


2) Create a text box, set its text property as follows, and ensure that it returns "true"



3) Create a second text box and set its text property as follows, and ensure it returns "true"

IsBlank(Last(Table({Field_A: 123, Field_B: 456}, {Field_A: 123})).Field_B)


4) Create a third text box and set its text property as follows

{Field_A: 123, Field_B: Value(TextInput1.Text)} in Table({Field_A: 123, Field_B: 456}, {Field_A: 123})

The problem is that the text box in step 4 will show "false" whereas the expression is actually "true"


Any idea of if and when this will be fixed would be very useful.


PS You can confirm that this is a bug by creating a fourth text box which will show "true" for the following:

{Field_A: 123} in Table({Field_A: 123, Field_B: 456}, {Field_A: 123})

I believe @AndyPennell could be interested in this behaviour

Hi Meneghino,


Thanks for your detailed steps.

I tried your scenario, I found that only when there are value for both two fields, can the third text box be True.

I am going to involve someone who is familiar with this issue to take a further investigation on it.


Best regards,
