Re: ognl can't handle converting from string to float?
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 Cimballi 写道: Frankie, here it works also with "0.0" entered in the UI.

Struts2.16 Source Code study:Help! What happened in request.getParameterMap()?
Hi, guys
I am studying struts2 source code.
I am wondering how struts2 get those parameters from a submitted
webform. So I traced the program from filterdispatch.class into
DefaultActionMapper.class(). I found a method
public void handleSpecialParameters(HttpServletRequest request,
ActionMapping mapping) {
.
Map parameterMap = request.getParameterMap();//the line
..
}
The thing I don't understand is before this line was called. debug show
the parameterMap in request is empty! however after this line. the
parameterMap was filled with values!!!And this methods is not traceable.
So my questions are:
1) where did struts2 /xwork2 get parameter from the webform and put them
into the request body.
2) what happened in that line?
Thanks in advance!

How to do pager with two select?
Hi guys, I got a problem implementing a Pager with two select. I have 2 select, a submit button and an iterator in a s:form,. Once user hit submit, the content in select will send to a action as criterias and load the data. I have no problem with that. BUT, BUT how can I add a pager in this form? I tried to use 4 links(first last.), once user hit a link, it will call a action but I can't get the value of select in the action! They are both null. I have been bothered for similar problems for a while, any suggestions and hints will be appreciated! Thanks in advance!

Re: Generating Dynamic radio button list
Jim Kiley ??:
You need to provide Struts with an actual List (or Set or the like). It
looks like you are providing a single String. You will need to parse that
String out into a List of Strings in order for to treat it as a
List.

Hi, JK,
Thanks for your help ,
The problem is I am trying to generate a form from the DB. So the number
of radio button list could vary. That could make the parsing method
quite complex.(Actually I am not sure how to do that yet), any suggestions?
