Hi,
v1.34.0 changes the behavior of the selectbox
widget. Here is our widget:
st.selectbox(
"QUERY",
key=query_selection_key,
options=st.session_state[query_select_options_key],
help=st.session_state.q_select_tooltip,
index=st.session_state[query_selection_index_key],
on_change=self._callbacks.q_selection_changed,
)
In our app, we use the index
argument to set the initial state. We have verified it works on all versions pre-v1.34.0. Here is how the widget lookson v1.34.0, when the index
argument is set to 0.
Here are the v1.34.0 widget variables state:
(Pdb) st.session_state[query_selection_key]
(Pdb) st.session_state[query_selection_index_key]
0
(Pdb) st.session_state[query_select_options_key]
['WS1_BinData']
Here is v1.33.0:
(Pdb) st.session_state[query_selection_key]
'WS1_BinData'
(Pdb) st.session_state[query_selection_index_key]
0
(Pdb) st.session_state[query_select_options_key]
['WS1_BinData']
On v1.34.0 the selectbox
session state value is None, on v1.33.0 it is set to ‘WS1_BinData’. I don’t see any changes in the v1.34.0 release notes that look to be the cause. Looks like an escape in your unit testing or an undocumented change in behavior.
thx
