Exception when setting setValueMap in ListGridField

[zaj]

Hello there,

I am trying to get the data for my Listgrid from the java class instead from the Datasource field. But I get this exception

10:48:49.274 [ERROR] [kaizenbehsa] Uncaught exception escaped
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

    at com.behsa.client.view.datamanagement.menu.ProductionLineController.initView(ProductionLineController.java:22)

My java code is like so

DataSource ds = DataSource.get("productionlineDS");

		listgrid = new MyListGrid();
		listgrid.setDataSource(ds);
		
		ListGridField name = new ListGridField("name");
		ListGridField bize = new ListGridField("bize");
		
		ListGridField pu = new ListGridField("pu");
		pu.setValueMap(CommonUtil.unitComboValueMap);
		
		ListGridField ways = new ListGridField("ways");
		
		listgrid.setFields(name,bize,pu,ways);

public static final LinkedHashMap<Integer, String> unitComboValueMap = new LinkedHashMap<Integer, String>();

static{				
		unitComboValueMap.put(0,"Gram");
		unitComboValueMap.put(1, "Liter");	
		unitComboValueMap.put(3,"Pcs");
		unitComboValueMap.put(4, "Other");
	}

and my datasource is

<DataSource ID="productionlineDS" serverType="sql" tableName="proine">
	<fields>
		<field name="id" type="sequence" hidden="true" primaryKey="true" />
		<field name="name"  type="ntext" required="true"/>
		<field name="bize"  type="integer" required="true"/>
		<field name="pu" type="integer" required="true"/>
        <field name="ways" type="integer" required="true"/>
	</fields>
</DataSource>

When you file a bug report, you need to provide us with the exact version of SGWT that you're using. This means the branch and date of the build that you've installed.

Hi Isomorphic,

I am using SmartClient Version: v10.0p_2015-05-08/PowerEdition Deployment (built 2015-05-08) with FF26.

Hi Isomorphic,

Can you please give me feedback on my issue.

The exception is being thrown because the SGWT Framework expects the keys to be Strings. We're going to make a change to allow Integer keys as well - this will likely be available in tomorrow's nightly build.

This has been fixed in SGWT 5.0p and newer and will be available in the nightly builds marked 06-26-2015. (The exception has been suppressed in todays builds, but some additional changes are needed.)
