Nice. Is it in the Power Edition dated 9-8 (today)? Or should I look for it tomorrow?

**Isomorphic** · 8 Sep 2014, 09:41

Tomorrow - September 9th

SmartClient Version: v9.1p_2014-09-09/PowerEdition Deployment (built 2014-09-09)
GWT 2.6.1
IE-11

I've upgraded to the latest nightly build. I've set the Tree property that you back-ported for us (thank you).

Code:

            treeGrid.setAutoFetchData(Boolean.TRUE);
            treeGrid.setLoadDataOnDemand(Boolean.TRUE);
            treeGrid.setAlwaysShowOpener(Boolean.TRUE);
            treeGrid.setDataSource(treeDataSource);

And here is the code in my service that returns an empty set (no more data to load for that folder that I clicked on).

Code:

            DSResponse dsResponse = new DSResponse();
            dsResponse.setData(new ArrayList<Map<String, Object>>(0));
            dsResponse.setStartRow(0);
            dsResponse.setEndRow(0);
            dsResponse.setTotalRows(0);

            return dsResponse;

I'm still seeing this error on the client side log:

Code:

Should I be returning something different to make this error go away?

**JLivermore** · 9 Sep 2014, 11:44

OK, I've resolved the error above in the last posting by changing the data part of the DSResponse

Code:

            DSResponse dsResponse = new DSResponse();
            dsResponse.setData(new ArrayList(0));
            dsResponse.setStartRow(0);
            dsResponse.setEndRow(0);
            dsResponse.setTotalRows(0);

            return dsResponse;

This is slightly different that what I have previously.

The Opener remains on the node now thanks to the TreeGrid.setAlwaysShowOpener() method call. Great, however, we need the state to remain in the '+' state and not change to '-' when there is an empty set returned.

How can we retain the '+' state of the opener when returning an empty set? Previously I was getting errors when returning a dummy record?

**JLivermore** · 9 Sep 2014, 12:42

Trying to isolate this error further, I've discovered that this error is being thrown on the client after my RequestTransformer is called and before the DSRequest is sent to the server. This is happening when I click on the node at the end of our tree (the leaf node):

I also get a pop-up dialog in IE-11:
Run debugger?
undefined
OK Cancel

I thought this error was after I returned a empty set in the DSResponse, but no, this error is happening on the client from clicking on the leaf node for load on demand?

**JLivermore** · 10 Sep 2014, 04:38

Further isolation of that error above, I'm seeing an exception thrown on the server before we see the exception thrown on the client:

javax.naming.NameNotFoundException
Resource /WEB-INF/classes/META-INF/services/javax.xml.parsers.DocumentBuilderFactory not found

Not sure if this is related.

Setting the debugger to break on all Exceptions, I'm seeing some Isomorphic exceptions being thrown on the server:

java.lang.NoSuchMethodException: com.isomorphic.datasource.FileSystemDSRepo._initialize()
java.lang.NoSuchMethodException: Method _initialize not found on class com.isomorphic.datasource.FileSystemDSRepo

These are thrown before we see the client error above. Any ideas?

**Isomorphic** · 10 Sep 2014, 05:37

These errors suggest that, as you previously speculated, your server and/or client-code is still sending back a DSResponse with either null for data or some other invalid value, such as a String, or a singular Record instead of the expected List/Array.

This may be because your server code is crashing; we would need the usual diagnostics (server logs, RPC tab request and response contents) to help debug further. Note that we always need this information in order to help.

The fact that Exceptions are thrown on the server is normal, so long as you do not see actual warnings or errors reported in the log (but again you've not shared the log so it's hard to be definitive).

**JLivermore** · 10 Sep 2014, 06:06

Server Log (just the portion when I click on the leaf node that causes the error) We don't see the exceptions I posted previously in the logs, only when I set the debugger to look at every exception thrown is when I see those exceptions above.

**Isomorphic** · 10 Sep 2014, 06:20

OK, the problem is definitely that your server is returning some kind of unexpected object - it's not null, and not an empty Array, so it may be a String.

You would normally be able to see what it is in the response tab of the Developer Console and we're not sure why you can't (we'll double check on whether observe the same thing with an obviously bad response), but regardless, you should be able to flip the "RPCManager" log category to DEBUG to see what's wrong with your response.

**JLivermore** · 10 Sep 2014, 06:25

So I understand you correctly, you think that the data being returned that goes into the TreeGrid is problematic?

**Isomorphic** · 10 Sep 2014, 06:26

Yes. An array is expected or null, and whatever you are returning is neither of these.

**JLivermore** · 10 Sep 2014, 06:28

When we have data, this is what is being sent back in the DSResponse:

Code:

        List<Map<String, Object>> list = dao.fetchPivotTableDataAsTreeOnDemand(spc);

        if(list == null) list = new ArrayList<Map<String, Object>>(0);
        DSResponse dsResponse = new DSResponse();
        dsResponse.setData(list);
        dsResponse.setStartRow(0);
        dsResponse.setEndRow(list.size());
        dsResponse.setTotalRows(list.size());

        return dsResponse;

This is not correct? If I understand you correctly, it should be

Code:

ArrayList<Map<String, Object>>

**Isomorphic** · 10 Sep 2014, 06:42

That code would be correct if the result was that Array or null makes it to the client. But that's not what's actually happening, based on the diagnostics you've provided.

Is there some reason you're not looking at the RPCManager log? That should clear things up.

**JLivermore** · 10 Sep 2014, 06:43

I made the change to return an array:

Code:

List<Map<String, Object>> list = dao.fetchPivotTableDataAsTreeOnDemand(spc);
        if(list == null) list = new ArrayList<Map<String, Object>>(0);
        DSResponse dsResponse = new DSResponse();
        dsResponse.setData(list.toArray(new Map[list.size()]));
        dsResponse.setStartRow(0);
        dsResponse.setEndRow(list.size());
        dsResponse.setTotalRows(list.size());

Note that these are the logs, DSRequest/DSResponse for the node expansion that returns the leaf node. It is this leaf node that blows up when I click on it (which I showed in posting #38).

Right. Now we need to see what the logs look like for the response that actually blows up.
