property initialization
I want to build a page with a form where a user can change her/his name. The
page displays a form with input fields for the users name (and password). I
would like the form to display the users current name. But this does not
happen. The field remains empty.
Can somebody please tell me what i am missing?
In a page file i have:
<page-specification class="myPackage.myPage">
<property-specification name="username" class="java.lang.String" />
<component id="aForm" type="Form"/>
<component id="nameInput" type="TextField">
<binding name="value" expression="username"/>
</component>
...
</page-specification>
The page implements pageRenderListener to retrieve at runtime the current user
details. This code gets called and indeed seems to work. The debugger showed
the correct user name was put into the setName() method.
This is the .java file:
public abstract class myPage extends BasePage implements PageRenderListener {
public abstract String getUsername();
public abstract void setUsername(String s);
public void pageBeginRender(PageEvent event) {
Visit v = (Visit) getVisit();
User p = v.getUser();
setName(p.getName());
}
...
}
Can somebody give me a hint? It looks like the TextField component for the
user name has already been rendered before the pageBeginRender() was invoked.
thanks!

Thank you for your reply.
Yes, you are right. I tried to edit out all non-essential java code before
sending the e-mail. In the process this error was introduced. My apologies.
The pageBeginRender() should be:
public void pageBeginRender(PageEvent event) {
Visit v = (Visit) getVisit();
User p = v.getUser();
setUsername(p.getName());
}
Actually, I introduced another one as well in the page file:
class="java.lang.String" should be type="java.lang.String"
But that is not the source of my problem. My question is: why does my
application not show the current user name?
Actually, I added a simple insert on my page, like this:
The username is: <span jwcid="testit"/>
.page:
<component id="testit" type="Insert">
<binding name="value" expression="username"/>
</component>
But it also shows an empty string.
why is that?

In your java code :

Shouldn't setName(p.getName()) be
setUsername(p.getName()) ?
