Format of Integer, BigDecimal in forms

[esschul]

Hi, in my form I use BigDecimal's and Integer's. When the user inputs values, they look like this: '100000'. When they re-open the form, after persisting, they get them in the way of '100 000', with the whitespace in the middle.

How do I change this behaviour ? SwingBinderSelectionStrategy? Any one got an example ? Thx!

By default, Spring RCP will use a simple text binder for Numbers. However, there's a NumberBinder you can use. By default, it's enabled for BigDecimals, but you can specify the specific Number type. With that binder you can:
- specify the format
- specify the number of decimals
- set left or right decoration (currency sign for example)
- enable/disable negative numbers

for example:

<bean id="euroBinder" class="org.springframework.richclient.form.binding.swing.NumberBinder" lazy-init="true">
        <property name="format" value="###,###,###,##0.00"/>
        <property name="nrOfDecimals" value="2"/>
        <property name="leftDecoration" value="€"/>
    </bean>

You can then use that binder in the formbuilders, or set it as the default for a type through the SwingBinderSelectionStrategy.

Yes! That was exactly what I needed

Is there any way to use these custom binders to format values in JTables?

For that, you'll need to create a TableCellRenderer

Can anyone provide/make a little tutorial on how to do this?
I am trying to implement this with the SwingBinderSelectionStrategy:

<bean id="binderSelectionStrategy" depends-on="serviceLocator"
 class="org.springframework.richclient.form.binding.swing.SwingBinderSelectionStrategy">
    <property name="bindersForPropertyTypes">
      <map>
      	<entry>
          <key>
            <value type="java.lang.Class">java.math.BigDecimal</value>
          </key>
          <bean class="org.springframework.richclient.form.binding.swing.NumberBinder" lazy-init="true">
		    <property name="format" value="###########0"/>
		    <property name="nrOfDecimals" value="0"/>
		  	<property name="leftDecoration" value="E"/>
		  </bean>
        </entry>
    </property>
</bean>

But somehow this fails. Am I missing something

Many thanks

Can you tell me how it fails?

Well the form is still showing the Integer or the Double with a thousand sign or decimal sign.

Form - Enter field (Integer) with the value: 3333333
Save/persist
Refresh
Form - Field shows: 3,333,333

I changed one of my field into a BigDecimal. After that, it was picked up correctly by the SwingBinderSelectionStrategy in my xml file. When entering a comma or a point, it is always represented as a point decimal separator (which is good).

For my integers/long it seems I need to have a converter... as it can't convert from source Integer to target BigDecimal
