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