Action class

public class ProductAction extends ActionSupport implements Preparable {
    private Document product;
}

Model

public class Document {
    private Map<String, Object> properties;
}

JSP

<s:textfield name="product.properties.PRODUCT_NAME" 
             value="%   {product.properties..PRODUCT_NAME}" 
             label="%{getText('label.PRODUCT_NAME')}" size="40" />

<s:textfield name="product.properties.SUPPLIER" 
             value="%{product.properties.SUPPLIER}" 
             label="%{getText('label.SUPPLIER')}" size="40" />

Product_name and Supplier are populated as Array in Map (Map<String, String[]>) properties.

PRODUCT_NAME : [Ljava.lang.String;@4e96ac47]
SUPPLIER     : [Ljava.lang.String;@1c90a278]

If I change the Document->properties to Map<String, String> it works fine.

But I want to retain Document->properties as Map<String, Object> because of other datatypes.

How to solve this issue, I want form data to be populated as String instead of String[].

I don't have multiple text fields with the same name.

what do you want to display, the key or the value. –  Uchenna Nwanyanwu Jun 12 '13 at 9:01

I want to pass private Map<String, Object> properties to dao layer for save, but Map<String, String[]> array is causing an issue where dao layer accepts only Map<String, String> –  Chethan C Jun 12 '13 at 10:24
    
Why are you holding different data types in the same map? –  Aleksandr M Jun 12 '13 at 10:41
    
Because it is the easiest way to process data, where I can have date, string, integer, etc –  Chethan C Jun 12 '13 at 10:42

Try this

<s:textfield name="product.properties.SUPPLIER" 
             value="%{product.properties.SUPPLIER[0]}" 
             label="%{getText('label.SUPPLIER')}" size="40" />

This will retrieve the first item in the Array

Thanks for the reply. I have no issues in jsp, but the actual problem is I don't want array in action Map<String, Object>. –  Chethan C Jun 12 '13 at 10:16

Modify the model and introduce methods to work with Map but save the data to the underlying Map like below

public class Document {
    private Map<String, Object> properties;


    public Map<String, String> getStringProperties() {
        //logic to populate Map<String, String>
        return new HashMap<String, String>();
    }

    public void setStringProperties(Map<String, String> stringProperties) {
        properties.putAll(stringProperties);
    }
}

In the jsp use stringProperties like below

<s:textfield name="product.stringProperties.SUPPLIER" 
             value="%{product.stringProperties.SUPPLIER}" 
             label="%{getText('label.SUPPLIER')}" size="40" />
