I have a conversion problem with doubles and null values.
JSP snippet:
<h:inputText
value="#{!empty MyController.category&&
MyController.category.treshold>=0? MyController.category.treshold:''}">
<f:convertNumber pattern="##0.##"/>
</h:inputText>
Class Category
public double getTreshold()
{
return this.mTreshold;
}
public void setTreshold(double treshold)
{
this.mTreshold = treshold;
}
This is working fine if I enter valid doubles.
The following message is displayed if I enter nothing in the input
field:
Exception setting property Threshold: of base with class
com.recommind.litigation.client.web.model.Category, Bean:
com.recommind.litigation.client.web.model.Category, property:
Threshold:, newValue: null ,newValue class: null method parameter class:
double, null
The getAsObject method of the NumberConverter returns null as expected.
What should I do now with the treshold property of the Category class ?
I tried without success:
- setTreshold(Double treshold)
- setTreshold(Number treshold)
A workaround is to set the value to 0 via javascript but this is not a
good alternative.
