Using IA 2010 SP1. I recently made a change to replace a Simple Get User Input panel with an Advanced one to fix a globalization problem (text not wrapping). Both panels have Yes/No radio buttons with variables $X_1$ assigned to Yes and $X_2$ assigned to No and No is selected by default. The associated code (written for the Simple input panel) tests $X_BOOLEAN_1$ = "1" to know if Yes was selected. However, this stopped working with the Advanced panel. I printed out the associated variables when I ran the installer and selected Yes. I see:
The boolean variables are not even set and the X_1 and X_2 have the boolean values. Before I make any code changes, is this to be expected? The IA help discussion about results variables makes me think that this is not correct.
The Simple Get User Input panel has only one "result variable" which contains the result of all the inputs, so the result is "_1", then "_2", then "_n" and depends on the number of fields (see VAR_BOOLEAN_X Variable in the IA help)
While the Advanced mode has only one variable per input so if you name it "VAR", result will be "VAR=1" if it was selected. So this is the boolean value. So your results $X_1$: 1 and $X_2$: 0 simply means that you named the result variable "X_1" for first choice and "X_2" for the second
Also take care if you support the console mode installer which also show different values (with '"' double quoted values).
