ZK Configuration Reference/zk.xml/The Library Properties/org.zkoss.zk.ui.input.grouping.allowed

Property:
org.zkoss.zk.ui.input.grouping.allowed

Applicable:
 globally in zk.xml via <library-property>
 nested in a zul file via <custom-attributes> (at page scope)

Default: true
[since 5.0.5]

Turn on/off whether the user is allowed to key in the grouping character when entering a number. The grouping character depends on the Locale. For example, it is a comma in English, and a dot in Germany. By default, ZK will allow the user to key in the grouping characters and the grouping characters are simply ignored when the input is parsed to a number.

Some people still get confused whether the application considers a comma as a decimal point or not, when he is new to the application. By disabling the entering of the grouping character will help in this case.

<library-property>
	<name>org.zkoss.zk.ui.input.grouping.allowed</name>
	<value>false</value>
</library-property>

If you want to disable it only for a particular page, you could specify it in the page's attribute (note: the page must be the root page). For example,

<zk>
<custom-attributes org.zkoss.zk.ui.input.grouping.allowed="false" scope="page"/>
<doublebox/>
</zk>
