JSF RI 1.1_01: UIInput component value was not set during render response

Question

I've just started to learn JSF, read corresponding chapters in J2EE guide and spec and tried to play little bit with JSF RI 1.1_01. I found very strange (at least for me) behaviour of regular input component (corresponds to inputText tag).
I have very simple example form (contains "select one", input component and command button). Corresponding backing bean has request scope. I set breakpoints in backing bean getters and during debug found:
1. On initial request both getters were called during rendering phase.
2. On form submit request getter for property bound to input component was called again (this looks strange for me) but getter for property bound to select box was not called (it looks as I've expected). This strange call occurs during validation phase. As far as I understand it was the following flow:
a) During initial request rendering response input box value wwas not stored in component state (I even may suggest that it was not set on component, just corresponding HTML tag with initial value was rendered).
b) On submit form submitted string value of input component was decoded from request parameters but local value was set to null (see above).
c) During validation phase submitted value was successfully converted and validated.
d) Then implementation had to detect component value change and called getValue() in order to obtain old value.
e) Implementation of getValue() first looked for local value field - it is null, then it should request for bound value from model.
I tried different ways to store state (client or server) but it was the same. Sadly MyFaces 1.1.1 implementation did even worse - local value of select was also null during first postback.
I wonder why it was implemented this way...
Thank you
