Hi,
I have successfully created a JSP to output a collection that looks like
this:
<logic:iterate id="permissionLanguage" name="permissionForm"
property="permissionLanguageData">
<tr>
<td>
<bean:write name="permissionLanguage"
property="languageName"/>
<html:hidden name="permissionLanguage" property="languageId"
indexed="true"/>
</td>
<td colspan="2">
<html:hidden name="permissionLanguage"
property="permissionTranslationId" indexed="true"/>
<html:text name="permissionLanguage"
property="permissionName" indexed="true" maxlength="200"/>
</td>
</tr>
</logic:iterate>
%%%%%%%%%%%%%%%%%%%%%%%%%%%
Which will in turn generate:
<tr>
<td>
Italiano
<input type="hidden" name="permissionLanguage[0].languageId"
value="it">
</td>
<td colspan="2">
<input type="hidden"
name="permissionLanguage[0].permissionTranslationId" value="1">
<input type="text"
name="permissionLanguage[0].permissionName" value="test">
</td>
</tr>
<tr>
<td>
English
<input type="hidden" name="permissionLanguage[1].languageId"
value="en">
</td>
<td colspan="2">
<input type="hidden"
name="permissionLanguage[1].permissionTranslationId" value="2">
<input type="text"
name="permissionLanguage[1].permissionName" value="test 2">
</td>
</tr>
%%%%%%%%%%%%%%%%%%%%%%%%%%%
and my form class looks something like:
public final class PermissionForm extends ValidatorForm {
/**
* The Collection to hold all of the PermissionLanguageData objects
*/
private ArrayList records = null;
/**
* Standard constructor.
*/
public PermissionForm() {
}
/**
* Get a specific row from the records ArrayList, based on index
*
* @param index The index of the row to retrieve
*/
public PermissionLanguageData getPermissionLanguage(int index) {
// a a bit of test code
System.out.println("index = " + index);
System.out.println("records.size() = " + records.size());
return (PermissionLanguageData) records.get(index);
}
/**
* Copies the data from the EJB into the form.
*
* @param value The Collection of PermissionLanguageData
*/
public void copyFrom( Collection value ) {
records = new ArrayList(value);
this.permission = ((PermissionLanguageData)
records.get(1)).getPermission();
}
/**
* Returns a Collection of PermissionLanguageData
*
* @return The Collection of PermissionLanguageData object
*/
public Collection getPermissionLanguageData() {
return this.records;
}
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%
This part is just what I wanted as it "should" allow me to edit my
recordHowever, I thought that this would work without a problem but I now
have the problem that when I submit my form, the Collection (it's an
ArrayList) that I am trying to populate/edit is empty. How do I ensure that
the ArrayList in my form class that I am submitting to contains the
Collection of objects that I am trying to edit? I am not sure how this would
be done because the form class gets called before the action class. All I
can think of is to add a couple of lines to add a new row into the ArrayList
in the getPermissionLanguage() method.
The error that I am getting is caused by a
java.lang.IndexOutOfBoundsException
Any suggestions that anyone may have would be greatly appreciated as I have
been stuffing around with this for some time now.
thanks
Jordan
