Bug: rows selected lags behind

[Tauvic]

Im working on an multi page application with tabs. I want to select multiple rows and get a list of the selected rows. When the users returns to the table I want to show the selected rows using pre_selected_rows.

But when get selected_rows it looks like the selection lags behind.
Looks to me for every selection i make table send two events, the original/old situation and the new situation.
Also it looks like the table keeps updating and looping sometimes.

Is this a bug? What is the correct way to do this? Has it to do with other incluences of multipage and tabs?
Im new to streamlit so I try now to test the most simple setup with a single page.

gb = GridOptionsBuilder.from_dataframe(df)
gb.configure_default_column(hide=True)
gb.configure_column("name",hide=False,width=300,tooltipField="name",
headerCheckboxSelection=True
)
gb.configure_column("branch",hide=False,width=150)
gb.configure_column("startDate",hide=False,width=90,type=["customDateTimeFormat"])
gb.configure_column("endDate",hide=False,width=90,type=["customDateTimeFormat"])
gb.configure_column("roles",hide=False,width=300,tooltipField="roles")
gb.configure_pagination(enabled=True,paginationPageSize=10,paginationAutoPageSize=False)
gb.configure_selection(use_checkbox=True,
selection_mode='multiple',
pre_selected_rows=selected_rows
)
gb.configure_grid_options(tooltipShowDelay=500)

table = AgGrid(df,
gridOptions=gb.build(),
enable_enterprise_modules=False,
update_mode=GridUpdateMode.SELECTION_CHANGED
)

selected_rows = [item['_selectedRowNodeInfo']['nodeRowIndex'] for item in table.selected_rows]
st.session_state[selected_name] = selected_rows

I'm seeing the same problem, but I'm using the GridUpdateMode.VALUE_CHANGED. The grid is always one event behind and fires multiple events

I now have added a button. When clicked i determine the selected rows and store in session state. This is a workaround for the somethwat strange behaviour. Now i can save selected rows and also show them when i switch between pages in a multipage App.
I see new errors in the browser log:
​ AG Grid: do not use api for selection, call node.setSelected(value) instead
t.selectIndex @ main.dc43edd4.js:2
​ AG Grid: suppressEvents is no longer supported, stop listening for the event if you no longer want it
