Re: Question regarding action form

[Manisha M Sathe]

Thanks for the reply, I looked further,

My guess, I am facing this problem because on jsp I am looping thr the 
thresholdCollection

--------------------------
   <logic:iterate name="reconThresholdEditForm" id="ReconThresholdBO" 
property="reconRuleBO.thresholdCollection" indexId="counter" type=
"admin.ui.bo.ReconThresholdBO">
         <b><bean:write name="ReconThresholdBO" property="thresholdOpertr"
/></b>&nbsp;
           <html:text name="ReconThresholdBO"  property="thresholdValue" 
size="30" maxlength="30"/>&nbsp; 
           <html:hidden name="ReconThresholdBO"  property="thresholdID"/>
&nbsp; 
   </logic:iterate>
------------------------------------------------
This is giving me multiple  input text   <input type="text" name="
thresholdValue" maxlength="30" size="30" value="1000000.00">&nbsp; 
So from form name is not clear that it is from reconThresholdEditForm.
reconRuleBO.thresholdCollection. 

I tried 
           <html:text name="reconThresholdEditForm"  property=
"reconRuleBO.thresholdCollection"/>&nbsp; 
           <html:text name="reconThresholdEditForm"  property=
"reconRuleBO.thresholdCollection.newThresholdVal"/>

first gives me address as expected, second gives class cast exception.

What I want is after submit I get back ReconRuleBO with collection of 
ReconThresholBO with new values. Any suggestion is highly appreciated.

Thanks
Manisha

Since you show your fields having static initializers, the only way to 
get a null reference there is if it's being overwritten. I'm not sure 
why Struts would be doing that.

I would suggest starting by adding tracing to the setter method to find 
out where/when it's being called with a null value. Then try simplifying 
your code and/or JSP until you isolate the cause.
