JavaScript exception on Button Click in current 5.1d

[Blama]

Hi Isomorphic,

I'm getting this Developer Console exception in 5.1d (SNAPSHOT_v10.1d_2015-07-21) I'm not getting in 5.0p (v10.0p_2015-07-15).
It happens on button click but is most likely related to your request/RPC code.

Developer Console GC43 (removed server name in logs):

Developer Console FF26 (different, less details, no change to logs, especially nothing removed behind "https"):

My code:

reloadButton.addClickHandler(new ClickHandler() {
	@Override
	public void onClick(ClickEvent event) {

		// resultGrid.fetchData(combinedAC);

		FilterSectionStack.this.parent.fetchData(computeCriteria());
	}
});

//...
//This is the fetchData called above:

public void fetchData(AdvancedCriteria combinedAC) {
	RPCManager.startQueue();
	funnelDS.fetchData(combinedAC, new DSCallback() {
		@Override
		public void execute(DSResponse dsResponse, Object data, DSRequest dsRequest) {
			if (dsResponse.getStatus() == DSResponse.STATUS_SUCCESS)
				funnelSectionStack.getFunnel().setData(dsResponse);
		}
	}, new DSRequest() {
		{
			setOperationId("countLeads");
		}
	});
	leadListReporting.fetchData(combinedAC);
	RPCManager.sendQueue();
}

Please also note the difference in the sent RPC requests in the attached screenshot. Therefore I think this might be related to the RPC code, not the button click.

This is pretty important for me, so if you need more details, let me know.

For completeness:

The RPC tab here looks like the one in the FF26-screenshot.

One other thing: It worked with previous versions of 5.1d, but I don't know when it stopped working.

[Blama]

Also tested with SNAPSHOT_v10.1d_2015-07-23/PowerEdition Deployment (built 2015-07-23), same error.

[Isomorphic]

This looks like a crash inside GWT Java application code being called from a click event. Is there any reason you think this crash is inside framework code?

Perhaps using less obfuscation you'd be able to see where in the code this is occurring.

[Blama]

Hi Isomorphic,

yes, please see the Development Mode Error message:

combinedAC.asString() in the debugger:

{
    "operator":"and", 
    "_constructor":"AdvancedCriteria", 
    "$H":10
}

I have no idea what "$H" is. This computes the criteria:

private AdvancedCriteria computeCriteria() {

	AdvancedCriteria masterdataAC = leadMasterdataForm.getValuesAsAdvancedCriteria();
	AdvancedCriteria creatorAC = leadCreatordataForm.getValuesAsAdvancedCriteria();
	AdvancedCriteria resellerAC = null;
	AdvancedCriteria resellerUserAC = null;
	if (User.isResellerUser())
		resellerUserAC = resellerUserForm.getValuesAsAdvancedCriteria();
	else
		resellerAC = resellerForm.getValuesAsAdvancedCriteria();

	AdvancedCriteria combinedAC = new AdvancedCriteria(OperatorId.AND);
	if (masterdataAC != null)
		combinedAC.addCriteria(masterdataAC);
	if (creatorAC != null)
		combinedAC.addCriteria(creatorAC);
	// either
	if (resellerAC != null)
		combinedAC.addCriteria(resellerAC);
	if (resellerUserAC != null)
		combinedAC.addCriteria(resellerUserAC);
	return combinedAC;
}

Before the return, the values of combinedAC.asString() in the debugger is:

{
    "operator":"and", 
    "_constructor":"AdvancedCriteria"
}

It changes after my 1st fetch in the Queue (that uses only SmartGWT APIs, see code above). See the attached screenshots.

Hi Isomorphic,

also please see the 1st request (the 2nd is not visible in the RPC tab because the program crashes before:

{
    dataSource:"V_REPORTING_FUNNEL", 
    operationType:"fetch", 
    operationId:"countLeads", 
    data:{
        operator:"and"
    }, 
    textMatchStyle:"exact", 
    showPrompt:true, 
    oldValues:{
        operator:"and"
    }, 
    requestId:"V_REPORTING_FUNNEL$62713", 
    fallbackToEval:false, 
    lastClientEventThreadCode:"MUP7", 
    bypassCache:true, 
    dataProtocol:"getParams"
}

Note how operator:"and" is under data/oldValues and that there is no criteria.

Best regards
Blama

[Blama]

Hi Isomorphic,

please disregard the last post. This seems to be the normal position for operator.
One more observation: If the change the UI so that the generated criteria are not empty, everything is working as expected.

Best regards
Blama

[Isomorphic]

We are not able to reproduce the error you are seeing. Perhaps, we are not taking into account important data that you have in your code, so, could you please post your test code to test it?

FYI: Removing the empty AdvancedCriteria from the ListGrid-fetches fixes the problem - so it seems to be a problem with empty criteria.

[Isomorphic]

The fix for the latest reported issue will be in nightly builds on 5.1d branch as of tomorrow, July 28. Please, check whether this fix solves your previous issue.

Hi Isomorphic,

SNAPSHOT_v10.1d_2015-07-29 seems to fix the bug in the sample as well as in my application.

Hi,

I know this is an old post but it's the first that popped up when searching for $H.

Some reason $H is getting shoved into criteria making queries fail as a result.

We are using:

GWT Version :	2.8.2
SmartGWT Version :	5.1p
SmartGWT Build Date :	10/01/2018 09:08
SmartGWT Edition :	Pro Edition

Best regards,
Luke

Hi,

I also have been struggling with "$H" in criteria for some time. Although it is ignored by grid's fetch and seems to be working fine I recently noticed that it somehow stops grid's caches from working. Another words, once "$H" occurs in grid's criteria, then grid does not update its records even though you add a criteria valid record through datasource.

Here a good example of producing "$H" into grid's criteria:

package pl.com.tech4.client;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.data.AdvancedCriteria;
import com.smartgwt.client.data.DataSource;
import com.smartgwt.client.data.DataSourceField;
import com.smartgwt.client.data.OperationBinding;
import com.smartgwt.client.data.RestDataSource;
import com.smartgwt.client.data.fields.DataSourceDateTimeField;
import com.smartgwt.client.data.fields.DataSourceTextField;
import com.smartgwt.client.types.DSDataFormat;
import com.smartgwt.client.types.DSOperationType;
import com.smartgwt.client.types.DSProtocol;

        lg.filterData(fb.getCriteria());
        SC.logWarn(JSON.encode(lg.getCriteria().getJsObj()));
    }

}

As you can see grid fetches data using criteria obtained from filterBuilder. If you run this example and look into dev console log you will see:

*15:48:56.860:WARN:Log:{
    "_constructor":"AdvancedCriteria",
    "operator":"and",
    "criteria":[
        {
            "fieldName":"code",
            "operator":"iContains",
            "value":"test"
        }
    ],
    "$H":5
}

From this point, grid does not react to updateCaches of its datasource.
