Logic:iterator reading from an array or collection

[Robert Hornsby]

Hi,
I am using the logic:iterator tag in a jsp using struct to output a
collection or an array of items. This works fine, however when the
user submits the form and I try to get the changed items the array
always come back null. I have tried this with array and collection
objects. Does anyone know why the collection is not getting
ititialized with the new data?

Thanks

My bean has the field

private FeaturedAuctions[] featuredAuctions;

and methods

public FeaturedAuctions[] getFeaturedAuctions()
{
return featuredAuctions;
}

public void setFeaturedAuctions( FeaturedAuctions[] featuredAuctions )
{
this.featuredAuctions = featuredAuctions;
}

The iterator sections of the jsp goes

<logic:iterate id="currentAuction"
name="adminFeaturedListForm" property="featuredAuctions">
<tr>
<td align="center" width="213">&nbsp;</td>
<td align="left" width="308"

I guess you'd need to address the form using an indexed property in your
input fields,
and provide indexed getters and setters.

Does your code above actually compile? It seems to contain nested quotes.

It sounds like a problem of scope:

I gess your form must be in the session scope.

Am I right ? ...

Sebastian is right: you need to use indexed properties. See
