ComboBoxItem.getEnteredValue() not a function?

[bade]

Hi,

SC_SNAPSHOT-2011-03-24/EVAL Deployment
FireFox 3.6.16

In my custom editor, which extends ComboBoxItem, I'm calling the getEnteredValue() and I'm getting the below error.

I have added a standalone test case. Type in "test%" as soon as you hit '%' the error is shown.

String ComboBoxItem.getEnteredValue()

Returns the raw text value typed into this form field, which can differ from FormItem.getValue() in various cases - for example:
for items that constrain the value range, such as a DateItem with enforceDate:true, or a ComboBoxItem with addUnknownValues:false
for items with a defined valueMap or edit value formatter and parser functions which converts display value to data value
while the item has focus if changeOnKeypress is false


Returns:
type: String - current entered value

public class Standalone implements EntryPoint {
		
	private static Canvas masterPanel = null;
	
	boolean pickerShowing = false;
	
	public void onModuleLoad() {
		 
		 devConsole = new Button("DEV Console");
		 devConsole.addClickHandler(new com.smartgwt.client.widgets.events.ClickHandler() {

				public void onClick(ClickEvent event) {
						SC.showConsole();
				}
		});	 
	  		
		//masterPanel should be a Layout
		masterPanel = new Canvas(); 
		masterPanel.setHeight100();
		masterPanel.setWidth100();
		masterPanel.setStyleName("pageBackground"); //background style from skin
		
		masterPanel.addChild(testCase14());
		masterPanel.draw();	
	}

	    public DynamicForm testCase14() {   
		  	  
	        DataSource dataSource = new DataSource();   
	  
	        DataSourceField myTestField = new DataSourceField();   
	        myTestField.setName("textField");   
	        myTestField.setTitle("textField");   
	        myTestField.setType(new MyComboBoxItem());   
	        myTestField.setEditorType(new MySimpleComboBoxEditor());
	  
	        dataSource.setFields(myTestField);   
	          
	        DynamicForm form = new DynamicForm();   
	        form.setHeight(170);   
	        form.setWidth(500);
	        form.setDataSource(dataSource);
	   
			return form;
	    }
}

public class MyComboBoxItem extends SimpleType {   
    public MyComboBoxItem() {   
        super("myComboBoxType", FieldType.ANY);   

    }  

}

public class MySimpleComboBoxEditor extends ComboBoxItem {
	
	public MySimpleComboBoxEditor() {
		super();
		
		setChangeOnKeypress(false);
		setCompleteOnTab(true);
		setSelectOnFocus(true);
		setAddUnknownValues(false);
		
		addKeyPressHandler(new KeyPressHandler() {
			
			public void onKeyPress(KeyPressEvent event) {
				
				if(event.getCharacterValue() != null && event.getCharacterValue().equals((int) '%')){
					//to avoid null pointers in grid
					MySimpleComboBoxEditor editor = (MySimpleComboBoxEditor) event.getSource();
					String enteredValue = editor.getEnteredValue();
					
//					String enteredValue = MySimpleComboBoxEditor.this.getEnteredValue();
					SC.logWarn("entered value is: " + enteredValue);
				}
				
			}
		});
	}

The below error is generated in our app, not the stand alone test case.
But you should get the same.

Hi,

Any update on this?

No resolution yet. We see the issue and will let you know when we have a solution or workaround.

I hate to be a pain, but is there a resolution yet?

thanx

Hi Bart
A workaround: Instead of using event.getSource() - try event.getItem()
This will give you back a TextItem instance but you can call the getEnteredValue() API on that object.
Also note that you may need to use 'keyUp' rather than 'keyPress' - the enteredValue is updated at the end of the keyPress thread so during the keyPress handler it will reflect the value without the keyPress character.

[bade]

Thanks... that seems to be working for the KeyPress event.

You are right, using the KeyUp event would be a lot better, only one big problem... what is the keyName for '%'?
'%' is a combination of two keys (shift + ù) => so it doesn't work with keyUp, as the KeyUpEvent doesn't have
a getCharacterValue() like the Keypress event :-(

My next step was to implement more or less the same logic in the "onEditor" exit. But sadly enough the 'enteredValue' is no longer available in the onBlur
when setAddUnknownValues(false). If setAddUnknownValues(true), the enteredValue is available in the onBlur.

Maybe it's best that I explain the idea behind all of this...

User can initiate a search in three ways:
1) typing a value and pressing '%' (hence the onKeyPress)
2) Typing the exact value and tabbing out => exact search is initiated.
If there's a result good, otherwise an error is shown 'not a valid value'.
3) Double clicking an empty field, search window is shown

Options 1 + 3 are working.
For option 2, I wanted to use the "enteredValue" and check if it exists in the underlying valueMap if so, great.
If not try to find an exact match (initiate search).

Regards,
Bart

Probably a couple of ways this could be achieved.

1) For catching "%" when the character value is not available you could use the keyName + EventHandler.shiftKeyDown(). This might allow you to use keyUp and keep your current approach

2) An alternative might be to get rid of addUnknownValues(false) and instead have just completeOnTab(true) and have either a changedHandler or editorExitHandler perform the search based on the entered value.

Will either of these get you what you need?
