I am writing a small sample application to learn how
to validate a PropertySelection in a table. I am using
an html table and a ForEach component.
Each row represents a Person object, with name as a
TextField component and favorite color as a
PropertySelection component. I am using a list inside
Home.java hold a list of three Person objects. It is
populated the first time that Home.java is activated.
Upon submit, each person in the
list is being update properly.
In my submit method I loop through the list of Persons
to validate that the favoriteColor is not the choice
"Red". If it is, then I want to mark the corresponding
propertySelection field with a "**" to the right of
the PropertySelection drop down.
In the submit method, I loop through the list of
persons. I check if a person.getColor().equals("Red").
The problem is that I don't know how to mark the field
as illegal because I can't call getComponent. The
rendered components have names like color, color$0,
color$1. Therefore, I can't call delegate.record. When
I call getComponent("color$1"), the system says,
component not found.
<pre>
public void save(IRequestCycle c) {
IValidationDelegate delegate =
(IValidationDelegate) getBeans().getBean("delegate");
Iterator iter = getPersons().iterator();
while(iter.hasNext()) {
Person p = (Person) iter.next();
if (p.getColor().equals("Red")) {
System.out.println("error detected");
// this doesn't work
IFormComponent comp = (IFormComponent)
getComponent("color");
delegate.setFormComponent(comp);
delegate.record("can't be red",
ValidationConstraint.PATTERN_MISMATCH);
} else {
System.out.println("NO error detected");
}
}
}
<form jwcid="@Form">
<table>
<tr>
<th>name</th>
<th>color</th>
</tr>
<tr jwcid="@Foreach" source="ognl:persons"
value="ognl:person" element="tr">
<td><select jwcid="[EMAIL PROTECTED]"
model="ognl:colors"
value="ognl:person.color"></select></td>
<td><span jwcid="[EMAIL PROTECTED]"
value="ognl:person.name"/></td>
</tr>
</table>
<input type="image" jwcid="@Submit"
listener="ognl:listeners.save""/>
</form>
</pre>
I hope the formatting above came through ok and that I
explained the problem well enough.
Thanks,
Larry Sherrill
