Re: GWT CELLTABLE How to restore old value in EditableTextCell?

Take a look at AbstractEditableCell#clearViewData(Obect key)

EditTextCell automatically recognizes when the pending value becomes the actual value (successful commit).  If it fails, you have to revert the value manually by clearing the ViewData, which contains the pending value.  The key in this case is the key associated with the value you are editing.  If you do not specify a KeyProvider, the key is the value itself.

Hi,

I want to used editableNumbercell like intger,decimal etc.. But there
is no such gwt widget present so I am using editable text cell and
using validation for numbers when user update value in cell.

Problem is that if validation fail then editabletext cell value
restored to old value.

intgerColumn.setFieldUpdater(new FieldUpdater<RecordInfo, String>() {
       public void update(int index, RecordInfo object, String value) {
           // Called when the user changes the value.
           if(value.matches("(-)?(\\d){1,8}")){
               object.setColumnInRecordEdited(true);
               object.setValue(value);
               RecordData.get().refreshDisplays();
           }else{
               Window.alert("Specify valid integer value for parameter");
               // How to reset old value here? currently updated
value immediately set to cell

           }

       }
   });

Any help or guidance in this matter would be appreciated.
