Validation for the Indexed properties dynamic fields in struts (JSP)

[Rithanya Laxmi]

Hi,

I have a JSP which will display the fields dynamically based on the Id which is passed to the DB , I am using indexed properties to fetch the data when you click the submit , how to do a validation for these dynamic fields.

Here is the snippet

<c:forEach items="${AdditionalInfoDetailsForm.additionalInfoItemsList}" var="additionalInfoItem">
out.println("inside the forEach loop");
<html:hidden name="additionalInfoItem" property="acctId" indexed="true"/>
<table>
<tr>
<td><label><c:out value="${additionalInfoItem.fieldName}"/>
<c:if test="${additionalInfoItem.mandatoryType == 'Required'}">
*
</c:if>
</label></td>
<c:if test="${additionalInfoItem.fieldType == 'Text'}">
<td><html:text name="additionalInfoItem" value =" " property="fieldType" indexed="true" /></td>
</c:if>
<c:if test="${additionalInfoItem.fieldType == 'DropDown'}">
<td><html:select name="additionalInfoItem" value=" " property="fieldType" indexed="true">
<html:option value="25">25</html:option>
<html:option value="35">35</html:option>
<html:option value="45">45</html:option>
</html:select>
</td>
</c:if>
<c:if test="${additionalInfoItem.fieldType == 'TextArea'}">
<td><html:textarea name="additionalInfoItem" value=" " property="fieldType" size="30" indexed="true" />
</td>
</c:if>
</tr>
</table>
</c:forEach>
<html:submit>Save</html:submit>

particularly here the "fieldType" in the form may be a text, textarea or a dropdown all these will use the same name="fieldtype". eventhough it is indexed how to do validate the "fieldtype" for a particular "fieldName" ?

I tried with validate() in the ActionForm, but without any luck as it will validate for all the 3 here which is text, textarea or a dropdown as well if they are displayed.
Please shed some light into this.

I was going through this link:

thanks.

Dear Laxmi,

I have used Indexed form in one of my Application. i have written a validation method in my action class .that method has a list as a parameter.
that list contains all the indexed propeties. and this method will return a hash map. which contains all the error messages of indexed properties.
and i will show the hash map values to the user.

  public HashMap validate(List l, String employeeid, String approver, String userid) {
        boolean list = false;
        HashMap hm = new HashMap();
        for (int i = 0; i < l.size(); i++) {
            Timesheet t = (Timesheet) l.get(i);
            String description = t.getDescription();
            String activity = t.getActivity();
            String company = t.getCompany();
            String project = t.getProject();
            String fromdate = t.getFromtime();
            String totime = t.getTotime();
            String billingtype = t.getYourbillingtype();
            System.out.println("company" + company);
            //  String approver = t.getYourapprover();

            if ((activity == null) || (activity.trim().length() == 0)) {
                hm.put("activity", "activity is empty");
            }
            if ((description == null) || (description.trim().length() == 0)) {
                hm.put("description", "description is empty");
            }


            if ((company == null) || (company.equals("Selectcompany")) || (company.trim().length() == 0)) {
                hm.put("company", "Please Select the Company");

            }
            if ((project == null) || (project.equals("Selectproject"))) {
                hm.put("project", "Please Select The project");
            }
            if ((billingtype == null) || (billingtype.equals("0"))) {
                hm.put("yourbillingtype", "Please Select the billing type");
            }
            if ((fromdate == null) || (fromdate == "") || (istime(fromdate))) {
                hm.put("fromtime", "From date Should not be empty");
            }
            if ((totime == null) || (totime.equals("")) || (istime(totime))) {
                hm.put("totime", "To time Should not be empty");
            }
            if (comparetimes(fromdate, totime).equals("error")) {
                hm.put("Comparetimes", "From Time Should not be greater than ToTime");
            }
            if (approver.equals("0")) {
                hm.put("yourapprover", "Select your Approver");
            }
            if (getLeaveandOndutyValidation(fromdate, employeeid)) {
                hm.put("leavevalidation", "You have applied for leave or onduty on this date");
            }
            if (checktime(fromdate, totime, userid)) {
                hm.put("checktime", "you have already applied on this From time");
            }
            if (findduplicates(l)) {
                hm.put("duplicate", "The timesheet List contains duplicate frometime or totime ");
            }


        }
        return hm;
    }

Thanks Srikanth, but my problem here is :-

Since the fieldType is dynamic as it can be a textfield , dropdown or a textarea with the same name="fieldType", how i can figure out this fieldType belongs to a particular fieldName. Like "Name" fieldName with a "Textfield" will have a mandatory validation check, "Age" fieldName with a "Dropdown" will not have a mandatory validation check?

Please shed some light into this and thanks for the response.
