Text input for multi-valued attribute

Question

I need to create an input form that will allow a user to enter any number of values for a particular attribute.

I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like:

public class Product {
  private String name;
  private ArrayList<String> tags = new ArrayList(5);

  {
    tags.add("");  //seed with 1 non-null element
  }

  ...accessors...
}

The input fields look something like:

    <h:dataTable id="tags" value="#{product.tags}" var="tag">
      <h:column><h:inputText id="t" value="#{tag}"></h:inputText></h:column>

My plan was to allow the user is to use javascript to add additional form fields as needed.

This type of setup gives me a 'Target Unreachable' error. What am I missing?

My problem now is that the setter for tags does not get called. Oddly enough, the setter for name does.

I am using JSF 1.1 on WebSphere 6.1

Answer 1

shouldn't "#{product.tag[0]}" be "#{product.tags[0]}"?
