Hi, Cimballi,
I find it out, it's a bug of xwork 2.1.2, not ognl~~.
The converstion failed in xwork2,
Acctually , xwork guys has already noticed this and have it
fixed since xwork2.1.3.
Xwork2.1.3. Changlong :
http://jira.opensymphony.com/secure/ReleaseNote.jspa?projectId=10050&styleName=Html&version=21790
<http://jira.opensymphony.com/secure/ReleaseNote.jspa?projectId=10050&styleName=Html&version=21790>
[XW-677 <http://jira.opensymphony.com/browse/XW-677>] -
double/float parameters not converted when <= 0
Struts2.1.8 is using xwork 2.1.6 so it didn't have this problem in
dealing with 0.0:-)

Frankie, here it works also with "0.0" entered in the UI.

Hi Cimballi,
Have you tried to set latitude = 0f (in java class) or 0.0 in the web
textfield and then submit the form?
I debuged the source code and I believe there is a bug in ongl when
handling float value 0,
Of course when the value is not 0f, ognl can handle converition from string
to float quite well.

I have a working case with this declaration :
private Float latitude; and getXxx setXxx.
And in the JSP : <s:textfield key="latitude" />
Using Struts 2.1.8.1

Hi,
Just curious,
Lib Version:
ognl 2.6.11/Struts2.1.6,
Initial setting:
I have a float variable utm1 in my java model class, the initial value
is set to to 0f,
Problem Desc:
when submitting the form, struts2 throw a error something like "can't
find the setter methods SetUtm1(String)".
Debug and trace info:
After the submitting, struts2 call ognl to set value of utm1, first ognl
look up for a converter to convert the para type(String) to the java
class type(Java.lang. float). However, there isn't any converter handle
such kind of convertion. So the ognl try to treat the para as a string
and apply the SetUtm1(String) methods.
Question:
Is it true that ognl didn't handle convertion from string to float? How
do you guys handle float variable in struts2 form?
Any comments? Thanks
Frank
