extended IDACall with handleDSRequest() override + DSRequest.addToCriteria() bug

[Isomorphic]

We've made these changes. Next smartgwt nightly build will throw an exception on method Criteria.addCriteria(criteria) if the passed criteria is an AdvancedCriteria or Criterion. Use Criteria.asAdvancedCriteria() to convert to AdvancedCriteria instead.

Just a note that we're actually going to do this a bit differently - Criteria.addCriteria(criteria) will be changed to throw an error if the passed criteria is an AdvancedCriteria (or Criterion) rather than essentially corrupting the criteria as it currently does.

We're doing it this way because we don't want to have the Criteria internally turn into AdvancedCriteria and yet still have "instanceof AdvancedCriteria" return false.

[Isomorphic]

That statement is correct, even so, the framework could automatically up-convert your Criteria to AdvancedCriteria in this instance, and we'll add that behavior at some point in the future so that even this (slightly odd :) series of calls works.

Hello Isomorphic,

you are (once again :) perfectly correct:

My client-side code was:

Criteria c = new Criteria() {
	{
		addCriteria(new Criterion("SHORTNAME", OperatorId.STARTS_WITH, "name_category"));
	}};
settingsDS.fetchData(c);

My new code is:

settingsDS.fetchData(new AdvancedCriteria("SHORTNAME", OperatorId.STARTS_WITH, "name_category"));

Is the following statement correct?
"When using AdvancedCriteria, work with Criterion inside the AdvancedCriteria. Use Criteria only for simple equality checks."
Does the constructor of the AdvancedCriteria in my code do that (create an empty add-AdvancedCriteria, then add a Criterion to it?

Thank you for your help & best regards,
Blama

[Isomorphic]

The root of the problem seems to be here:

criteria:{
fieldName:"SHORTNAME",
operator:"startsWith",
value:"name_category"
},

This is clearly intended to be AdvancedCriteria, but it lacks the required _constructor:"AdvancedCriteria" attribute, so it is treated as simple Criteria.

So you actually need a client-side fix to avoid this bad criteria being submitted. But you haven't shown how this request ends up being sent.

My T_SETTINGS.ds.xml for the sake of completeness:

Hi Isomorphic,

please see this DS-Request from the Server-log and what the IDAServlet does with it.
The suspicicous part is the FROM T_SETTINGS WHERE (('1'='1' AND '1'='1' AND '1'='1') AND (T_SETTINGS.TENANT_ID = 0 AND T_SETTINGS.TENANT_ID IS NOT NULL)).

I'm using the current nightly (v9.0p_2013-11-13/EVAL Deployment).

The server request comes in from the client with some criteria and is added a criterion for "TENANT_ID" by my IDACall (which I register in web.xml):

import java.io.IOException;

	@Override

			IOException {
		Integer i = User.getUserId(request);
		if (i != null) {
			try {
				RequestContext context = RequestContext.instance(this, request, response);
				RPCManager rpc = new RPCManager(request, response);
				rpc.setUserId(i.toString());
				// rpc.setAuthenticated(true);
				// rpc.setUserRoles((String) roles);

				// call processRPCTransaction() to iterate through all RPCRequests and
				// DSRequests and execute them
				processRPCTransaction(rpc, context);

			} catch (Throwable e) {
				handleError(response, e);
			}
		} else {
			super.processRequest(request, response);
		}
	}

	@SuppressWarnings("unchecked") 
	@Override
	public DSResponse handleDSRequest(DSRequest arg0, RPCManager arg1, RequestContext arg2) throws Exception {

		} else if (arg0.getOperationType().equals(DataSource.OP_FETCH)
				|| arg0.getOperationType().equals(DataSource.OP_UPDATE) || arg0.getOperationType().equals(DataSource.OP_REMOVE)) {

			} else
				newAc = new AdvancedCriteria(DefaultOperators.And, new Criterion[] { new SimpleCriterion("TENANT_ID",

			arg0.setAdvancedCriteria(newAc);[/B]

			// arg0.addToCriteria("TENANT_ID", "equal",
			// User.getUserTenantId(arg0.getHttpServletRequest()));
		}
		return super.handleDSRequest(arg0, arg1, arg2);
	}
}

For me it seems that I'm either completely misusing AdvancedCriteria.asCriterion() or there is a bug in the method leading to the triple '1'='1'. But I don't think I'm misusing the API as this use is suggested in the AdvancedCriteria's constructor javadoc (http://www.smartclient.com/smartgwte...erion[]%29).

Thank you & best regards,
