Hello!

I've a very strange problem using JSF-RI 1.2, Spring 2.55 and Hibernate using Oracle OC4J 10.1.3.3 as JEE conatiner. It is strange, because it only occuring on a Linux- platform, a standalone container running in windows does not show the problem.

If I try to set a number value in a JSF page, the following error shows up:

SEVERE: /blaetter/hBlatt.xhtml @171,81 value="#{hblattBean.hblattDTO.sehwertDTO.ferneRechtsSph}": Can't set property 'ferneRechtsSp' on class 'at.sozvers.bva.loewe.online.dto.SehwertDTO' to value '1'.

But nothing special about this property:

The JSF property:


<h:inputText id="frsId" label="FRs" style="text-align:center" disabled="#{hblattBean.hblattDTO.readonly}" value="#{hblattBean.hblattDTO.sehwertDTO.ferneRechtsSph}" size="3" maxlength="8">
<f:convertNumber locale="de"/>
</h:inputText>


The object:

private Float ferneRechtsSph;

public void setFerneRechtsSph(Float ferneRechtsSph) {
this.ferneRechtsSph = ferneRechtsSph;
}

public Float getFerneRechtsSph() {
return ferneRechtsSph;
}


Is there a possibillity that this error deends on the java version? But couldn't verify this by now.

Thanks in advance for your help!

Stefan

Hi!

Ar least, now I know which part is causing trouble:

If I remove <f:convertNumber locale="de"/> from the JSF page, everything works fine, butb unfortunatley I need this line for localisation...

Any ideas?

Just a wild guess - and it shouldn't be doing this, since it's a validation error, not an Exceptional one: Are you seeing differences between decimal formats (comma vs. point)?

Yes, there are differences. Here in our country "." is for grouping and "," for seperating integer digits from fraction digits.

Try changing the data type from float to double.

Unfortunately this isn't an option, because we need float values (values like "1,25" are most likely)

Welcome to the JavaRanch, Deepthi!

We prefer that rather than awakening old dormant message threads ("raising zombies") that people start new threads.

We do need more specific details on your particular problem, however.
