Execution queue of setEmbeddedData() in addOnload within a loop?

Question

Hi everyone,
I have a loop repeating n questions in random order for t times. The questions contain references to embedded fields. The embedded fields need to be changed in each iteration of the loop. The fields are not pre-populated.

I use javascript in addOnload() to change the embedded field data. What happens is that in the first iteration of the loop the embedded fields are not set. In the second iteration the fields are set.

It seems that addOnload() executes the setting of the embedded data only after the page loads (?).

Pseudocode to illustrate

For (t in times) {
        set embedded data field of question n_i
       display question n_i
       set embedded data field of question n_i + 1
      display question n_1 + 1
      ...
    }

I cannot pre-populate the fields. I tried hiding the first loop iteration and using t+1 loop iterations, but this does not execude the code in iteratio no 1.

Any recommendations?

I am happy to use javascript directly without the embedded fields, i don't mind. :D

Embedded data fields don't get set until they get sent to the server (i.e., you go to the next page). I'm not clear on what your embedded fields actually are or what they are being set to. One solution would be add a text display question to the beginning of the block followed by a page break, then add the JS that sets the embedded data field to that script and then have it click the next button.
