Here's the stuff that's working with an Array property.
<logic:iterate id="predicate" name="AdvancedQueryForm"
property="predicates" indexId="index">
<tr>
<td class="checkbox">
<html:checkbox property='<%="predicates[" +
index + "].enabled"%>'/>
</td>
<td class="predicate">
<html:select property='<%="predicates[" +
index + "].displayTag"%>'>
<html:options
property="fieldNames"/>
</html:select>
</td>
<td class="op">
<html:select property='<%="predicates[" +
index + "].op"%>'>
<html:options
property='<%="predicates[" + index + "].ops"%>'/>
</html:select>
</td>
<td class="value">
<html:text size="40"
property='<%="predicates[" + index +
"].value"%>'/>
</td>
<td class="action">
<html:image property="resetbutton"
src="images/rowinsertbefore.gif"
alt="Insert before."
onclick='<%="rowInsertBefore( " +
index + " )"%>'/>
</td>
<td class="action">
<html:image property="resetbutton"
src="images/rowinsertafter.gif"
alt="Insert after."/>
</td>
<td class="action">
<html:image property="resetbutton"
src="images/rowdelete.gif"
alt="Delete."/>
</td>
</tr>
</logic:iterate>
Here's my propery access
/** Get search predicates.
* @return Predicate [] search predicates. */
public Predicate [] getPredicates() { return predicates; }
/** Set criteria.
* @param list criteria list. */
public void setPredicates(Predicate [] predicates)
{ System.out.println("SETTING PREDICATES"); this.predicates
= predicates; }
And my reset
/** Reset all properties to their default values.
* @param mapping The mapping used to select this instance.
* @param request The servlet request we are processing. */
public void reset(ActionMapping mapping, HttpServletRequest request)
{
System.out.println("RESET!!!!");
action = "";
profileNames = new String[0];
currentPredicate = 0;
predicateCount = 1;
predicates = new Predicate[predicateCount];
predicates[0] = new Predicate();
type = "";
includeLockedLoans = false;
}
The problem with this approach seems to be that one submit my Array size
gets defaulted (to one) and then populated so modifying the Array size
dynamically seems difficult.
