Problem with indexed property !

[Moniphal Say]

Hi all,

With Struts, I use logic:iterate tag to iterate over a list of informations. In each iterate, it has the input text field.
When the action is execute, it has the errors.

This is my code in JSP page :

<logic:iterate scope="session" id="indexInfo" name="indexInfoList" >
<tr>
<td>
<html:text indexed="true" name="indexInfo" property="name" value="" />
</td>
</tr>
</logic:iterate>

"name" is the property of an object indexInfo.

And this is my Action Form :

public class SearchForm extends ActionForm {

private String[] name = new String[20];
...........

public String[] getName() {
return name;
}

public void setName(String[] strings) {
name = strings;
}
............
}


And this is my Action Servlet :

...........

String[] indexValue = ((SearchForm)form).getName();

...........


And when the action is execute, the error message is :

exception

javax.servlet.ServletException: BeanUtils.populate
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821)

<logic:iterate scope="session" id="indexInfo" name="indexInfoList" >

Is your bean indexInfoList in session scope?

[Moniphal Say]

Yes Shankar, I have saved the bean "indexInfoList" in the scope "session" !
I've tried this :
in the JSP, I take out the code : <html:text indexed="true" ..... />
and also take out the property : name and its setter and getter methods from my actionForm and actionServlet.

The errors messages disappear !!!
So I think the problem is with the <html:text indexed="true" ..... /> and in actionForm. But I really dont know how to solve it. And also I have to put it in my project.

Your help would be great !

Have you tried
<nested:text property="name"/>

instead of <html:text> ?

(Don't remember, but you might have to set the type in your iteration, something like:
<nested:iterate ... type="com.somepackage.IndexInfo">

[Shankar Narayana]

Hi,

I had gone through the <html:text> documentation for the indexed
property and according to my understanding, your code should work in this
way.

I suppose "indexInfoList" is of type collection/array/etc... , so when you
are putting the "indexed=true" in <html:text> it is interpreted as
indexInfo[1].name, indexInfo[2].name for each iteration incrementing the
count. Verify your indexInfoList bean. I had a similar situation but i
have used the nested tags.


Hope this should give some ideas to solve your problem.
