PORefreshing my fragment not working like I thought it should

Body
copied!<p>I have this nice method in my ListFragment I call to fill out the details of my other fragment:</p> <pre><code>private void showClientDetails(int pos) { myCursor.moveToPosition(pos); int clientId = myCursor.getInt(0); if(mIsTablet) { // Set the list item as checked getListView().setItemChecked(mCurrentSelectedItemIndex, true); // Get the fragment instance ClientDetails details = (ClientDetails) getFragmentManager().findFragmentById(R.id.client_details); // Is the current visible recipe the same as the clicked? If so, there is no need to update if (details == null || details.getClientIndex() != mCurrentSelectedItemIndex) { // Make new fragment instance to show the recipe details = ClientDetails.newInstance(mCurrentSelectedItemIndex, clientId, mIsTablet); // Replace the old fragment with the new one FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.replace(R.id.client_details, details); // Use a fade animation. This makes it clear that this is not a new "layer" // above the current, but a replacement ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE); ft.commit(); } } } </code></pre> <p>It is called when the user clicks on a client in the ListFragment view:</p> <pre><code>@Override public void onListItemClick(ListView l, View v, int position, long id) { mCurrentSelectedItemIndex = position; showClientDetails(position); } </code></pre> <p>This works great, but then another FragmentActivity can change the data that this displays so I thought this would work:</p> <pre><code>@Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); //update the client list incase a new one is added or the name changes if(requestCode==1899) { myCursor.requery(); theClients.notifyDataSetChanged(); showClientDetails(mCurrentSelectedItemIndex); //now if client was edited update their details in the details fragment } } </code></pre> <p>Now I know the line:</p> <p><code>if (details == null || details.getClientIndex() != mCurrentSelectedItemIndex) {</code></p> <p>Prevents the block of code being reached when its called in my onActivityResult. So if I remove that <code>if</code> statement, then things freak out and the ft.commit() has a hissy fit and gives me the error:</p> <p>`07-08 16:53:31.783: ERROR/AndroidRuntime(2048): Caused by: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState</p> <p>So I guess what I am trying to do isn't as cut and dry as it sounds, it makes no sense to me since I can do that onListItemClicked all day and the fragment displays the details of the newly clicked client constantly very well...</p> <p>I even tried this in my <code>onActivityResult</code>:</p> <pre><code>//simulate a click event really fast to refresh the client details showClientDetails(0); showClientDetails(mCurrentSelectedItemIndex); </code></pre> <p>that does nothing, is it im trying to call something from the onActivityResult which isn't a Ui thread or what not?</p> <p>I do have this in my code of the ListFragment as well</p> <pre><code>@Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putInt("currentListIndex", mCurrentSelectedItemIndex); } </code></pre> <p>Is this what the error is complaining about?</p>
