EL with Struts

Hi,

I need to access an indexed property inside a <logic:iterate> tag.

<logic:iterate id="col" indexId="i" name="sheetForm" property="cols"
type="de.fortu.ccdata.sheet.Column">
...
<util esignrule rule="${bean.editable[i] == false}" styleClass="readonly"/>
...
</logic:iterate>

The class behind "bean" has an ArrayList with a getter method

public boolean getEditable (int index)

The code above results in an exception saying:
javax.servlet.jsp.el.ELException: Unable to find a value for "editable" in object of class "de.fortu.ccdata.tree.LeaveNode" using operator "."

How do I have to modify my code to access the i-th element of that ArrayList?

Thanks,
Ralf.

You should write a method for your bean that returns an ArrayList that takes no arguments. Then, you should loop through the elements in the ArrayList and call the getEditable() method on them.

It is sorta covered in the JavaRanch Style Guide.
