Bug with SpinnerItem

[dmius]

I have create SpinnerItem:

SpinnerItem spinner = new SpinnerItem();
	spinner.setName("fieldName");
	spinner.setDataPath("fieldName");
	spinner.setMin(0.0);
	spinner.setMax(50.0);
	spinner.setStep(0.1f);
	spinner.setDefaultValue(1.0f);

and later I setup value

	Float value = 2.2;
	FormItem field = styleForm.getField("fieldName");
	if (field != null) {
		field.setValue(value);
	}

And on screen i see value: 2.200000047683716
If I click up or down i see 2.300000047683716 or
2.100000047683716 accordingly.
How I can limit quantity of deduced signs after a comma?
But if I save again value from DynamicForm I receive 2.2 again.
Also How I can see step not 1.0 but 1.00000000xxxxxxx in this case...

Do you see this in development only or even in web mode? If you want a faster response, always post a minimal but complete standalone testcase with an onModuleLoad() rather than snippets of code.

An example of using SpinnerItem without DataSource

package mytest.client;

import java.math.BigDecimal;
import java.util.Map;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.smartgwt.client.data.Record;
import com.smartgwt.client.widgets.form.DynamicForm;
import com.smartgwt.client.widgets.form.fields.SpinnerItem;
import com.smartgwt.client.widgets.form.fields.events.ChangedEvent;
import com.smartgwt.client.widgets.form.fields.events.ChangedHandler;

/**
 * Entry point classes define <code>onModuleLoad()</code>.
 */
public class Testsgwt implements EntryPoint {

    /**
     * This is the entry point method.
     */
    public void onModuleLoad() {

        final DynamicForm styleForm = new DynamicForm();
        SpinnerItem spinner = new SpinnerItem();
        spinner.setName("fieldName");
        spinner.setMin(-50.0d);
        spinner.setMax(50.0d);
        spinner.setStep(0.1d);
        styleForm.setFields(spinner);

        /*
         * Sets the value.
         */
        Double setValue = new Double(12.1d);
        Record record = new Record();

        // Using String here also can work.
        record.setAttribute("fieldName", setValue);

        styleForm.editRecord(record);

        spinner.addChangedHandler(new ChangedHandler() {

            @Override
            public void onChanged(ChangedEvent event) {

                /*
                 * Gets the value.
                 */
                Double returnValue = null;

                Map<String, Object> valueMap = styleForm.getValues();
                Object tempVal = valueMap.get("fieldName");
                if (tempVal instanceof Float) {
                    returnValue = new Double((Float) tempVal);
                    GWT.log("Instance of Float.");
                } else if (tempVal instanceof Integer) {
                    returnValue = new Double((Integer) tempVal);
                    GWT.log("Instance of Integer.");
                } else if (tempVal instanceof Double) {
                    returnValue = (Double) tempVal;
                    GWT.log("Instance of Double.");
                }

                GWT.log("Before round up: " + returnValue.toString());

                // GWT-Math is used. See [url]http://code.google.com/p/gwt-math/[/url]
                int decimalPlace = 2;
                BigDecimal tempValue = new BigDecimal(returnValue);
                BigDecimal roundedValue = tempValue.setScale(decimalPlace,
                        BigDecimal.ROUND_HALF_UP);
                Double roundedReturnValue = roundedValue.doubleValue();
                GWT.log("After round up: " + roundedReturnValue.toString());
            }
        });

        styleForm.draw();

    }
}

valueman,

did you get your problem solved? I have the exact same issue and need a solution. (I might try your gwt-math bit if nothing else works...)

[tdk]

looks like it works in Production mode, kinda strange tho'...
