JSF Float Conversion
- by Phill Sacre
I'm using JSF 1.2 with IceFaces 1.8 in a project here.
I have a page which is basically a big edit grid for a whole bunch of floating-point number fields. This is implemented with inputText fields on the page pointing at a value object with primitive float types
Now, as a new requirement sees some of the fields be nullable, I wanted to change the value object to use Float objects rather than primitive types. I didn't think I'd need to do anything to the page to accomodate this.
However, when I make the change I get the following error:
/pages/page.xhtml @79,14 value="#{row.targetValue}": java.lang.IllegalArgumentException: argument type mismatch
And
/pages/page.xhtml @79,14 value="#{row.targetValue}": java.lang.IllegalArgumentException: java.lang.ClassCastException@1449aa1
The page looks like this:
<ice:inputText value="#{row.targetValue}" size="4">
<f:convertNumber pattern="###.#" />
</ice:inputText>
I've also tried adding in <f:convert convertId="javax.faces.Float" /> in there as well but that doesn't seem to work either! Neither does changing the value object types to Double.
I'm sure I'm probably missing something really simple but I've been staring at this for a while now and no answers are immediately obvious!
