First of all, thanks much Merrill for helping out.
Here are the code snippets:
1-The relevant portions of your ActionForm public class MyActionForm extends ActionForm {
// Other beans/EJBs fetch and populate results and bkupResults ArrayList in this form;
//then this form is displayed (upon "success" mapping from there)
private ArrayList results = null, bkupResults = null;
...
public ArrayList getResults() {
return results;
}
public void setResults(ArrayList results) {
this.results = results;
}
public void setResult(int index, MYBean o) {
this.results.set(index, o);
}
public MYBean getResult(int index) {
return (MYBean)this.results.get(index);
}
...
/*
Currently I am not sure how I can unset the checkboxes to the original state - for now I just want to get the checkboxes to work based on user clicks - then I will figure out the contents of this reset method (to make checkbox change from checked to to unchecked). However this is what I have now. If I remove the if check I get a null pointer exception!!
*/
public void reset(ActionMapping mapping, HttpServletRequest request)
{
if (results != null) {
//hmmm...why do I need this check? results = (ArrayList)bkupResults.clone();
logger.severe("Results after reset:"+results);
}
}
}
2-The relevant portions of the javaBean that is in your List public class MYBean {
...other private fields...
private boolean flag = false;
...
public boolean isFlag() {
return flag;
}
public void setFlag(boolean val) {
this.flag = val;
}
...other setters/getters and toString()
}
3-The relevant portions of the JSP (<html:form tag, and the iterate portion) <logic:iterate id="result" name="MyActionForm" property="results"
indexId="index" type="MYBean">
<html:form action="/MyAction.do">
<!-- showing other properties here -->
<html:checkbox value="true" property='<%= "result[" + index + "].flag" %>'/>
<!-- showing some other properties here -->
<html:submit property="action">
<bean:message key="delete.submit"/>
</html:submit>
</html:form>
</logic:iterate>
<html:form action="/MyAction.do">
<html:submit property="action">
<!-- In this commit() method I am processing the checkboxes --> <bean:message key="commit.submit"/>
</html:submit>
...
</html:form>
4-The relevant portion of your struts-config.xml file <form-bean name="MyActionForm" type="form.MyActionForm"/>
<action path="/MyAction"
name="MyActionForm"
parameter="action"
type="action.MyAction"
input="/mypage_tiledef.jsp"
validate="true">
<!-- Am not yet validating; the form's validate() just returns null -->
<forward name="success" path="/mypage_tiledef.jsp"/>
</action>
Thanks,
T. Vetri
