RE: Struts 1.0.2 checkbox - Error Message: No collection found

[Mike Finn]

Yu,
This looks like the same problem I posted this AM (subject = logic:iterate
and "no collection found"). I found that if the array actually has data in
it, everything works OK. It's only when it's empty or null that it blows up.
Post if you find a solution and I will do the same. I am going to try to
step through the source this afternoon.
Mike

Sorry I forgot that the reset method in the ActionForm looks like this:
==============================================================
public void reset(ActionMapping mapping, HttpServletRequest request)
{
cat.debug("ConflictResolutionForm reset");
/*
this.checked = false;
this.linenum = null;
this.field = null;
this.level = null;
this.currentValue = null;
this.overrideValue = null;
*/

 if(conflicts != null) {
            for(int i=0; i< conflicts.size(); i++) {
                ((ConflictBean) conflicts.get(i)).setChecked(false);
            }
        }
}
==============================================================
Looking forward to hearing any hints, thank you very much,
Yanhui

Hi All,

We are using struts verions 1.0.2 here.  I have a problem using checkbox in
a jsp, getting No collection found error.  Here is my sample code and I
really appreciate if anyone can give me a hand on this.

in jsp
=====================================
        <logic:iterate id="conflicts" name="ConflictResolutionForm"
property="conflicts"
                 type="com.pioneer.sales.terrmaint.demo.ConflictBean">
        <tr>
                <td><html:checkbox name="conflicts"  property="checked"
/></td>
                <td><bean:write name="conflicts" property="field" /> </td>
                <td><bean:write name="conflicts" property="level" /> </td>
                <td><bean:write name="conflicts" property="currentValue"
/></td>
                <td><bean:write name="conflicts" property="overrideValue" />
</td>
                </tr>
        </logic:iterate>
=======================================

in ConflictBean class
========================================
        private String linenum = null;
        private String field = null;
        private String level = null;
        private String currentValue = null;
        private String overrideValue = null;
        private boolean checked = false;

        // all public getters and setters for all the String attributes

        public boolean getChecked() {
                return checked;
        }
        public void setChecked(boolean _checked){
                checked = _checked;
        }
==================================================

in Action class
==================================================
        ConflictResolutionForm conFlictForm = new ConflictResolutionForm();
        ArrayList conflicts = new ArrayList();
        // Fill in the list here

        ConflictBean cb = new ConflictBean();
        cb.setLinenum("1");
        cb.setField("Field 1");
        cb.setLevel("Area");
        cb.setCurrentValue("012345678");
        cb.setOverrideValue("012345678");
        conflicts.add(cb);

        conFlictForm.setConflicts(conflicts);
        return (mapping.findForward("conflictresolution"));   //set up in
struts-config.xml
====================================================

in ActionForm
=====================================================
        private ArrayList conflicts = null;

        public ArrayList getConflicts() {
                return conflicts;
        }

        public void setConflicts(ArrayList _conflicts) {
                conflicts = _conflicts;
        }

        public ConflictBean getConflicts(int index) {
                return (ConflictBean) conflicts.get(index);
        }

        public void setConflicts(int index, ConflictBean conflict) {
                conflicts.set(index,conflict);
        }
======================================================


Any help would be greatly appreciated.  What I did wrong here? Maybe
multibox is what I need?
