InvalidSetError when trying to set value of field

Hello,

this is a really simple question but still I cannot see anyone with this problem.

I am only trying to set the value of a field using:

this.getField("myField").value = 3;

but I get an InvalidSetError.

However I can set the value if I use the importTextData function. So the field name is correct, it is writable but doesn't accept a value.

Thank you

that happens when you run this code in the console window:

this.getField("myField").value

If the field is empty, then nothing happens.

If there is a value in it, then it writes the value to the console.

Can this be caused by some sort of security or protection of the PDF file?

Thank you

Yes, that's most likely the cause.
