Suppose there's a sample code below:
I put zscript code outside of Window component, when zscript code try to access components inside Window, an 'Typed variable declaration: Attempt to resolve method: getValue() on undefined variable or class name username...' error is reported.
If move zscript code into Window, it will work.
This sample code works ok when using ZK 3.5.2
Sample code:
<?xml version="1.0" encoding="UTF-8"?>
<?taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c" ?>
<?page title="FaxBox WebAccess"?>
<zk>
<zscript>
<![CDATA[
public OnTimer()
{
// Keep alive
}
public LDAPLogin ()
{
String u = username.getValue();
String p = password.getValue();
info.setValue (u);
}
]]>
</zscript>
<window id="login_window" title="登录" border="normal" width="400px" sizable="false" mode="overlapped"
position="center, top" style='margin-top:50px;'
onOK='LDAPLogin()' xmlns:h="http://www.w3.org/1999/xhtml">
<timer id="timer" running="true" delay="30000" repeats="true" onTimer="OnTimer()"/>
<div style='text-align:center;'><label style='font-family:黑体; font-size:20px;'>FaxBox</label></div>
<grid>
<rows>
<row>
Domain/Email Account
<hbox><textbox id="username" constraint="no empty"/>@DOMAIN.com</hbox>
<zscript>
username.focus ();
</zscript>
</row>
<row>Password <textbox type="password" constraint="no empty" id="password" /></row>
<row><label/><hbox><button label=" Login " onClick="LDAPLogin()"/></hbox></row>
</rows>
</grid>
<label id="info" style="color:red;"/>
</window>
</zk>
Hi,
Exactly that's a bug of ZK 3.5.2, the formal use should be
<zscript>
<![CDATA[ //@DECLARATION
public void OnTimer()
{
// Keep alive
}
public void LDAPLogin ()
{
String u = login_window.getFellow("username").getValue();
String p = login_window.getFellow("password").getValue();
login_window.getFellow("info").setValue(u);
}
]]>
</zscript>
You could not access components within a window directly.
So, the bug has been fixed since Zk 3.5.3
Thanks for notice.
Thank you for your response hideokidd.
That piece of code works with ZK 3.0.x and 3.5.0/1/2, if it's a bug, it's not just exists in ZK 3.5.2.
The "The ID Space" section in zk-dev-guide show a restricted component access method, but this BUG/feature provide a convenient component access method.
suppose there are 3 level ID spaces like this:
<window id='w1'>
<window id='w1_1'>
<window id='w1_1_1'>
<label id='labelTest' value='Test'/>
</window>
</window>
</window>
Hi,
Obviously the original use of component access is convenient, but it doesn't obey the rule of namespace. Maybe we will make a shortcut to achieve this without using getFellow() method.
BTW, there is a discussion similar to the problem, please see

Thanks.
