[jira] Created: (TOBAGO-335) and
Double object in backing bean
<f:convertNumber type="number"> and Double object in backing bean
-----------------------------------------------------------------
Key: TOBAGO-335
URL: https://issues.apache.org/jira/browse/TOBAGO-335
Project: MyFaces Tobago
Issue Type: Bug
Components: Core
Affects Versions: 1.0.10
Reporter: Guido Dubois
If you need to clear an input field, the easiest way is to use an object type like String, Date or Double. So you can set it simply to null and the field will be cleared. But in case of Double there will be a problem with <f:convertNumber>.
In RI there is the same problem. See issue https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=286 for more details.
This workaround helps:
<tx:in value="#{bbg.f3}" label="field3" labelWidth="120px">
<f:convertNumber type="number" maxFractionDigits="2" pattern="#,##0.00" />
</tx:in>
...
private Number f1;
private Double f1double;
...
public Number getF1() {
return f1double;
}
public void setF1(Number f1) {
this.f1double = f1.doubleValue();
}

[jira] Commented: (TOBAGO-335) and

Guido Dubois commented on TOBAGO-335:
-------------------------------------
correction:
public void setF1(Number f1) {
this.f1double = null;
if (f1 != null) {
this.f1double = f1.doubleValue();
}
}
This doesn't works for empty fields.

-------------------------------------
If using simple type double, the field is initially preset with "0,00" (assumed pattern="#,##0.00") and it seems that you can't clear the field...

-------------------------------------
This works with empty fields!
The error message corresponds to an other field of simple double type.
