The specific example I am trying to do is build two if-else expressions and use the evaluation on one if expression as the input for a second if expression.
let expression1 = if(condition_on_input, fixed_value, fixed_value);
let expression2=if(condition_on_input_1, value_from_input2, fixed_value);
and then I want to evaluate this composite $(expression2(input1, $(expression1(input2))))
as if(condition_on_input_1, if(condition_on_input2, fixed_value1, fixed_value2), fixed_value3);
However, if I try the normal way to avoid commas, the expression $(expression1(input2)) statement gets partially evaluated first, this seems to put the commas back into the expression as normal and prevents using it as an input for expression2.
I've attached a dummy dataset where I can reproduce these issues in QlikSense.
So, following the escaping rules, and replacing special characters, on that data I can get two expressions which separately work:
let eNiceYesNo_char_replace = 'if('&chr(36)&'1 = 1 or '&chr(36)&'1 = "Y" or '&chr(36)&'1 = "y"'&chr(44)&' ''Yes'' '&chr(44)&' ''No'')';
let f_partB_char_replace = 'if(match('&chr(36)&'1'&chr(44)&' ''B'' '&chr(44)&' ''C'')'&chr(44)&' '&chr(36)&'2'&chr(44)&' null)';
and in the expression editor we can see that
$(eNiceYesNo_char_replace(OUTCOME2)) expands to if(OUTCOME2=1 or OUTCOME2="Y" or OUTCOME2 = "y", 'Yes', 'No')
and $(f_partB_char_replace(MANAGEMENT_PROCESS, OUTCOME2)) expands to
if(match(MANAGEMENT_PROCESS, 'B', 'C'), OUTCOME2, null) . These both work as they should.
However, the nested expression $(f_partB_char_replace(MANAGEMENT_PROCESS, $(eNiceYesNo_char_replace(OUTCOME2))))
expands to if(match(MANAGEMENT_PROCESS, 'B', 'C'), if(OUTCOME2=1 or OUTCOME2="Y" or OUTCOME2 = "y", null) and here it was truncated at the comma.
I have also tried replacing all of the commas with ; and then running replace(expression, ';', ',') but when I replace the commas with ';' in the expression strings it breaks the loading script.
Any advice on how to make this work would be appreciated.
