RE: Problem with logic:equal?
You have defined the user bean between the logic:equal tag this will visible if it is
out of scope.
Like
If(something==true)
{
User userName = someUser;
}
if(something!=true){
userName
}
if you try to use user it is out of scope
logic:equal name=elem property=status value=10
bean:define id=username name=UserContainer
scope=session property=user.username /
logic:equal name=elem property=caseworker
value=%= (String) username %
td class=text bean:write name=elem
property=annCreated //td
td class=text bean:write name=elem
property=filnavn //td
td class=text html:radio property=checked
idName=elem value=annID//td
/logic:equal
logic:notEqual name=elem property=caseworker
value=%= (String) username %
td class=textdis bean:write name=elem
property=annCreated //td
Thanks

Subject: Problem with logic:equal?
I have this code in my jsp page:
logic:iterate id=elem name=annList
tr
logic:equal name=elem property=status value=0
td class=text bean:write name=elem
property=annCreated //td
td class=text bean:write name=elem
property=filnavn //td
td class=text html:radio property=checked
idName=elem value=annID//td
/logic:equal
logic:equal name=elem property=status value=10
bean:define id=username name=UserContainer
scope=session property=user.username /
logic:equal name=elem property=caseworker
value=%= (String) username %
td class=text bean:write name=elem
property=annCreated //td
td class=text bean:write name=elem
property=filnavn //td
td class=text html:radio property=checked
idName=elem value=annID//td
/logic:equal
logic:notEqual name=elem property=caseworker
value=%= (String) username %
td class=textdis bean:write name=elem
property=annCreated //td
td class=textdis bean:write name=elem
property=filnavn //td
td class=textdis bean:write name=elem
property=caseworker //td
/logic:notEqual
/logic:equal
/tr
/logic:iterate
But this just gives me an error message telling me that cannot resolve
symbol
symbol : variable username
But this variable has been defined, hasn't it??
Any suggestions?

Re: Problem with logic:equal is actually a problem with bean:define and Weblogic 8.1
I tried just running bean:define id=username name=UserContainer property=user.username / Test: %= username % in a jsp file under Tomcat and that works ok, but doing the same under Weblogic 8.1 with SP 1, generates a cannot resolve symbol error. Is this a bug in WL or am I doing something wrong?

Re: Problem with logic:equal and bean:define
Hi Stephen, If you are interested in why it is happening look at the .java file that is created by jsp compiler. I've spent some time doing it but eventually I had given up because there were too many lines of code to analyze. Nevertheless I'm sure there is an important reason :-). Despite I don't know why it is happening, I know how to solve the problem and that is why I'm replying to your email. What you have to do is to define a bean with the same name outside of any logic:... tag. When you repeat bean:define ... inside logic:.. tag bean's value just changes. And that is all. You can then use bean as you want. What you must remember is to keep the same classname of the bean in each bean:define ... statement. When you use value attribute it is done automatically, assuming that the classname is java.lang.String. If you use another attribute (name, property and so on) don't forget to add type attribute as well. Regards, Pawel stephen.chambers wrote: All, When I use the bean:define tag inside a logic:equal, why doesn't the scriptinh variable created stay in scope outside of the logic tags? What am I doing wrong? Code snippet below: logic:equal name=myattribute value=5 bean:define id=myvar value=50/ /logic:equal Once outside of the logic tags, even out.print(myvar); results in null.

Re: Re: Problem with logic:equal and bean:define
Pawel, I appreciate the suggestion, but I couldn't get it to work somehow. It keeps coming back with compile errors that java.lang.String is already defined. I put exactly the same bean:define tag, albeit with a different value outside and above the logic:equal tag. Which struts are you using 1.0.2 or 1.1 b1?

Re: Problem with logic:equal tag
One time I had this problem. Double check to make sure that you have the %@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic % at the top of the page.

RE: Problem with logic:equal tag
Make sure you have included the logic taglib in your page %@ taglib uri="WEB-INF/struts-logic.tld" prefix="logic" % If you dont have this, the logic tags are just ignored and you will get the output you described.
