Instance-bound overrides Tag attributes ?

I bound a selectboolean_checkbox Tag to a UISelectBoolean component. The instance was set to the value "false", but the attribute in the tag was set to "true". The outcome is a NOT SELECTED checkbox.
Can one generally say, that binding always overrides values set throught the attribute of a tag?
thanx!

If you'e specified a value binding expression, in this case, that will be used to set the underlying component's value. You can see that in the tag handler's "setProperties" method.

Unable to Deploy WAR file (Unknown assembly root-tag attribute: version)

Hello,
I created a simple web application with eclipse + tomcat plugin + struts2 (JPA Spring Hibernate ) and created the WAR file using the tomcat plugin compiler. When I deploy the war file into Tomcat 6 the file is deployed properly and i can view the website properly. But when I try to deploy the the WAR file from Oracle 9i Application Server I get the following error.

During the initial upload the previous error doesn't show anymore, however, I'm getting this new error and currently I'm a bit at a loss since i included the spring.jar library file in my war file. I tried the new war file in Tomcat and the war file deploys fine. Am I missing a configuration or setup ?

EL in jtls tag attributes?

I keep getting an exception when I try to use an expression in a jstl tag attribute and I don't understand why. I'm new to jstl, but everywhere I look online people are using these expressions just like I'm trying to. In fact, if I'm not mistaken, this is what the expression language was originally developed for, so I'm extra confused.
an example:
<c:forEach items="${someClass.someCollection}" var="myItem">
blah blah blah
</c:forEach>throws this exception:
According to TLD or attribute directive in tag file, attribute items does not accept any expressionsthis happens when I run it with taglib uri set to http://java.sun.com/jstl/core but if I point it at a local .tld I get no exception. It appears that the tld at java.sun.com/jstl/core has a validator that disallows expressions in tag attributes, but I don't understand why. Will I always need to supply my own .tld files?
any clarification of whats going on would help scrape off some of my shiny newbieness, and thus would be greatly appreciated.
thanks

what webserver are you running? And what version of JSTL are you using?
You should go for a webserver that has JSP 2.0 support (Tomcat 5.5 for example) and you should use at least JSTL 1.1. You can download the latest version (1.2) here:
http://people.apache.org/builds/jakarta-taglibs/nightly/projects/standard/
Also be sure that in your web.xml file the servlet version is set to 2.4. It will look something like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
</web-app>Your best bet is to install an IDE like Netbeans and let it create a web project for you, then all the basic setup steps are performed for you and you have the correct library versions.

Repeating Regions and Editable Tag Attributes?

I want to produce a template that will let users create pages
that list items as a thumbnail image and a short text description,
one after the other.
I can set this up as a repeating region, but I would also
like to make only certain attributes of the image editable (src and
alt for example). However, when I use editable tag attributes to do
this, the image in each repeated region ends up with the same
attribute values - when I add a new repeat region and then change
the src tag through the Template Properties dialog,
all of the images take on the same src value. Looking at the
code, it looks like the editable instances in each repeated region
get the same name, and so I can see that DW will get confused.
Is this a limitation in DW? Is there a work around anyone can
suggest?
TIA

So, you have some number of people who are editing the child
pages and you
want to constrain their editing choices? Are you using
Contribute?
Anyhow, I am not aware of any convenient way you can do
something like this
using DW's Template features.

Struts2 and Tiles2 - Error executing tag: Attribute 'title' not found.

I keep getting Error executing tag: Attribute 'title' not found when I go to the baseLayout.jsp page. I am figuring it is not seeing the tiles.xml file, but I have placed it in the /WEB-INF directory like every web page I have found says too. Any help or pointers would be appreciated.

I was playing around with it some more and was trying to follow this page:
http://www.vaannila.com/struts-2/struts-2-example/struts-2-tiles-example-1.html
I made sure I had the same jar versions. I still get the same exception in the Browser, but I get a few more log messages in the tomcat log;
Obviously I have something configured wrong. I'll see what searching brings up, and of course any help would be appreciated.

OAF:Unable to bound a viewobject attribute in child VO using a viewlink

Hi
I am using the following piece of code to bound the viewobject attribute to prompt in my inner table.
OADataBoundValueViewObject promptBV =
new OADataBoundValueViewObject(colHeaderBean,"Counter1","MRStatusLastAccVO1");
While the above piece of code works for all the viewobjects attributes, it is not working if I use an attribute of inner Viewobject(i.e the VO which is linked by viewlink with the outer VO). This is done in processRequest()
In processFormRequest(), I am overriding the values in the inner VO by querying it from another VO(if show event happens). All the overridden values are shown on the UI correctly.
However if I use the same view attribute which is shown on the UI correctly, to bound with the prompt , the prompt is shown as blank.
I have 2 inner VOs. For both of them bounding of view attribute doesn't work, while it works for all other VOs
Can you please tell what must be the reason for this? Is it because they are linked by view link to outer VO?
Thanks
Abhinav.

Hi Raj,
We have 4 buttons on page Search Clear, ADD_ANOTHER_ROW and SAVE
I have already posted code for all 3 buttons.
Sample code written for Search button click,
Sample code written for ADD NEW ROW button click,
Sample code written for Save button click,
What i missed out it code for CLEAR button, its a single line of code on that button,
    pageContext.forwardImmediatelyToCurrentPage(null,false,null);
This is how the page code which makes a call to individual functions above,
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
    super.processFormRequest(pageContext, webBean);
    PlannerapprAMImpl am = (PlannerapprAMImpl)pageContext.getApplicationModule(webBean);
    if (pageContext.getParameter("Go")!=null)
    am.Manualsearch(pageContext);
    if (pageContext.isLovEvent())
      String lovInputSourceId = pageContext.getLovInputSourceId();
    if (pageContext.getParameter("Clear")!=null)
    pageContext.forwardImmediatelyToCurrentPage(null,false,null);
     if(pageContext.getParameter("Save")!=null)
      am.save(pageContext);
    if(ADD_ROWS_EVENT.equals(pageContext.getParameter(EVENT_PARAM)))
        am.frCreateRow();

Variable Substitution with tag attribute

Hi,
is possible to use variable substitution with tag attribute? as follow:
<root directory="xxx" filename="yyy">
<....
</root>
using variable substitution for directory : root,1,directory,1
root,1,filename,1

Hi,
I solved my problem using Dynamic Configuration to set the FileName and Directory fields in Adapter Specific Configuration. To use Variable Substitution only accept element in XML.
Thanks for all.

How to tag attribute member with standard dimension member in EIS

hi,
would any one please help me how to tag attribute member with standard dimension member in EIS
THANK U IN ADVANCE

In your OLAP model, view columns for the base dimension table. Go into the column properties and for the columns that have Attribute values highlight them and click the Attribute button.
Go into Metadata Model and those fields will be available to drag into your outline as attribute members.
Once in the outline, go into the properties of the attribute and assign the level of the base dimension they associate with.

JSP ${} expressions in JSF tag attributes

Does anyone know why the expert group decided not to allow ${} style expressions within JSF tag attributes? I understand that a different syntax is needed to implement the 'late binding' #{} expressions used to link input controls to form beans, but not why the JSF tags actually prevent the use of immediately evaluated ${} expressions for accessing variables in the page scope in JSP 2.0.
I know there has been a lot of discussion about this and other threads mention a security loophole that would be opened up by allowing expressions like #{blah.${someProperty}}, but I'm not sure why this sort of thing would cause a problem. Is there any way to enable this behaviour, such as editing the JSF tag library descriptors to allow runtime expressions (horrible though that sounds)? Or perhaps another JSF implementation that supports both immediately evaluated and late-binding expressions? It seems a rather unnecessary restriction that is going to cause much confusion and mistyping for all...
Thanks in advance,
Keith.

Thanks Adam, I see the problem now. It's a fairly obscure loophole but serious nonetheless. Of course, this problem could also be avoided by not using request parameters within JSF tags as it doesn't affect the majority of legitimate uses for expressions.
I have to disagree with you about mixing ${} and #{} expressions though. The majority of developers will be used to writing ${} expressions in JSTL and JSP text and so will expect them to do work the same in JSF tags. Judging by the number of posts in this forum about being unable to use page scope variables in JSF tags this issue is already confusing a lot of people.
As a rule of thumb, "use ${} for expressions that are output to the page and #{} for binding controls to backing beans and invoking methods" (which perform clearly distinct functions) is a lot simpler and easier to learn IMHO than the current one, which is "use ${} for expressions that are output to the page except within a JSF tag, where you use #{} for the same thing and also to update form values and invoke action methods"! (OK, I'm exaggerating a little for effect, but you get the point... :-)
I agree that mixing both types of expression in the same attribute might be a little confusing, but this is an unlikely edge case that should probably be prevented in value binding or action attributes anyway. It's more of an issue for label values where mistyping one for the other is already very common and, although not especially difficult to debug, is just another pitfall awaiting the unwary JSP developer. I'm not sure that JSP expressions would be much more difficult to debug anyway as the value and method bindings will simply not work, which is pretty obvious as soon as you try and test the thing.
Is this something that the EG would be prepared to reconsider for the next release of JSF, or perhaps getting the security loophole addressed in the next JSP spec? In the meantime, is there any reason that developers shouldn't enable runtime expressions in the TLD file provided that they're willing to live with the consequences?
(Sorry to harp on about it, but I've already had several complaints about this after recommending JavaServer Faces for a major development project at ingenta.com.)
Many thanks,
Keith.

Extract function not working with tag attributes

Hi all,
I have an xml document stored in the db as an xmlType. I am trying to use the extract function to retrieve values. The extract will work fine on tags without attributes. Any tags with attributes or tags beyond the tags with attributes will not be accessible.
<tag1>
<tag2>hi</tag2>
<tag3 att="hello">bye</tag3>
<tag4> hi again </tag4>
</tag1>
In the example above I can extract tag2 values but not tag3 or tag4 values.
here is my select statement
works
select e.xmlval.extract('/tag1/tag2').getStringval()
from test_xml e;
does not work
select e.xmlval.extract('/tag1/tag2/tag3').getStringval()
from test_xml e;
does not work
select e.xmlval.extract('/tag1/tag2/tag3/tag4').getStringval()
from test_xml e;
Any ideas?

Hi all,
Found the issue. The problem was that I was not specifying the second argument to the extract function.
The tag attribute that I was not handling was xmlns="".
I used this atttribute as the second argument in the extract function and now I am off and running.
Hope this helps someone.
Cheers

Custom tag attribute calculated by scriptlet expression

Hi,
          If I set the rtexprvalue subelement of the attribute element in my tld to
          "true", should I be able to dynamically determine the value of my custom tag
          attribute using a scriptlet expression?
          When I include the custom tag reference:
          <prod:getCategory id="category"
          categoryID="<%=request.getParameter("catID")%>" scope="page"/>
          it actually gets written to the html as:
          <prod:getCategory id="category" categoryID="2133" scope="page"/>
          and is not recognized as a jsp tag.
          I am using weblogic 6.0 sp1.
          Thanks in advance!

I had the same problem in a design a couple of months ago and could not get around it so I switched the functionality into code and out of the tag lib.
I take it you are trying to do something like this?
<%
String value="hiworld";
%>
<mytaglib:saysomething value="<%=value%>"/>

Custom tag attribute question

How to assign value of expression or variable to custom tag attribute in jsp?

Using TAG Attributes within JSF Tags

I'm using some .tag files for templating purposes. I'm using two tag attributes via <@% attribute %> directive. How can i access this attribute to do something like follows.
<%@ tag display-name="Area de Trabajo" language="java" %>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@ taglib prefix="t" uri="http://myfaces.apache.org/tomahawk"%>
<%@ attribute name="title" required="true"%>
<%@ attribute name="location" %>
<t:div styleClass="zonaArea#{(not empty location) ? location : 'Global'}">
<h:panelGrid columns="1">
<h:outputText value="#{title}" />
</h:panelGrid>
<jsp:doBody />
</t:div>

Hola Alberto.
Any luck? Did you worked that around?
I'm just trying to do the same thing...
Tried to do something like:
<%@attribute name="enabled" type="java.lang.String" %>
<h:outputText value="test: #{requestScope['enabled']}" style="font-weight: bold;" /> to no avail...
Let me know, please!

Updating tag attributes in design time

I have a design time renderer for my custom component... As the component renders itself in design time, I set some of the component properties from within the renderer... The property sheet correctly shows those values... However, the associated JSP tag in the source view does not show those attributes... The JSP tag attributes dictate the runtime behavior and since they are not set properly, my component misbehaves.
How do I make sure that the tag attributes sync up with the property sheet values?
Also, what is the motivation behind the property sheet displaying the component values and not the JSP tag values? Having it the way it is right now opens itself up to a bunch of out-of-sync problems like the one I encountered.
Thanks,
Keyur

Ok - here are a couple of scenarios:
1. I have a component, say chart component associated with a connection component like this:
<my:connection id="connection1" />
<my:chart connectionId="connection1" />The user first drags and drops the connection component. The ID connection1 is automatically associated to it. Next he drops the chart component. Now, I would like to automatically populate the connectionId attribute without the user having to type it in manually. I am able to do that (in design time) in the renderer of the chart component - I programmatically look for a connection component on the page and set the connectionId attribute of the control. And when I do that it correctly shows the connectionId attribute populated in the property sheet but the corresponding tag attribute is not.
Sure enough, at runtime, it is the tag attribute values that count and since those are not updated by the IDE, it does not work as expected.
2. Creator updates the style attribute when I move or resize the component. Now, I also have position attributes left and top defined on my component and I use these attributes at runtime to position my component. So, in design time I extract the left and top values from the style attribute and set them on the component. But again, the tag attributes are not populated and so the component is not positioned properly.
#1 is to convenience the user so that he doesn't have to manually enter values for attributes which can be automatically populated at design time.
In fact for #1, I would ideally like to show the user a drop down list of all the connections available to him in the property sheet and select the first one by default. Is this possible?
#2 is for backward compatibility reasons - We already have runtime renderers in place which use left and top attributes explicitly to render the components at runtime. And this is not restricted to left and top only but other client attributes as well - such as borders, backgrounds etc. which we expose as separate attributes.

JSP in custom tag attributes...

Sirs,
          A very nice feature from a development perspective, would be the ability
          to use JSP code within custom tags. Say I have a page on which I wish
          to give all the information on a widget. Say further that I have
          implemented a tag that writes out all the info of a widget as HTML
          table. I would like to write something like this:
          <mytaglib:widgetTag widgetID="<%=request.getParameter("widget_id")%>"
          />
          As far as I know, in the current implementation of custom taglibs this
          does not seem to be possible. Instead you end up writing something like
          this:
          <mytaglib:widgetTag>
          <mytaglib:getWidget><%=request.getParameter("widget_id")%>"</mytaglib:getWidget>
          <mytaglib:displayWidget />
          </mytaglib:widgetTag>
          Which is much more like a scripting language than a heirarchical XML .
          Now, I could always just use the request object within the tag helper
          classes, but this gives up flexibility and can introduce security
          issues, and it also makes the tags much more difficult to work with...
          In short, we should push for JSP evaluation of tag attributes. Weblogic
          could leap ahead of other app servers in this area (making up for the
          custom tag performance issues, to be solve in sp6) and Sun would, once
          again, follow Weblogic's lead and rewrite the standard to include this
          functionality.
          Regards,

Carson,
          Perhaps the problem is that you are treating custom tags like one would
          construct an imperative language. I have never had to put Java or use beans
          or %= or even parameters to tags into a JSP because of custom tags.
          The real problem is writing/packaging/maintaining all those tags; sure could
          use a tool that did just that ;-)
          Peace,
