Using a session variable in an xapp:if

, ,
1

X-Application Version: 4.1.1
Tamino Version : 4.1.4.1,
Platform : WinXP
WebContainer : Tomcat 4.1.17
JDK Version : 1.4.1

I am trying to use a variable in an xapp:if statement:
<xapp:if condition=“equal” value=“${passwordin$}” select=“/User/Password”>
Passwords are equal</>
</xapp:if>

The value being compared is ${passwordin$} and not the contents of passwordin. I only get the “Passwords are equal” when /User/Password contains ${passwordin$}.
I have tried all sorts of other variations without success. Is there any way I can do the comparison against a variable?

Thanks Priscilla

Hello,

I checked the code as well as the source code of X-Application. The result is that for the attribute ‘value’ the variable resolving mechanism is not invoked. This is not a bug. The intention when we introduced the variables handling to provide this feature only within the query context (=> xapp:action and xapp:directcommand tag).

However, the plugin mechanism of X-Application should allow you to modify the behavior. I send you two code snippets:
(1) For the file xapplication.xml to define the plug-ins ‘equal’ and ‘notequal’
(2) For a Java class you can compile into the WEB-INF/classes directory of your application (perhaps you should use another package name and class name).

After this, the attribute ‘value’ should be resolved.

Bye
Christian.


xapplication.xml:

<xapplication>
...
	<plugins>
...
		<node>
			<action name="equal"
			        method=" myapplication.mysubpackage.mysubsubpackage.MyNodePlugin.equal">
				<arg>arg</arg>
				<arg>variables</arg>
   		</action>
			<action name="notequal"
			        method=" myapplication.mysubpackage.mysubsubpackage.MyNodePlugin.notEqual">
				<arg>arg</arg>
				<arg>variables</arg>
			</action>
