Struts portlet data binding

Struts project using syntax like
<c:out value="${bindings.RaeCustomersView1.labels['Role']}"/> works fine unless deployed as a struts portlet.
As a portlet all the bindings are null.
This is a major pain !!!
Has anyone any ideas.

ok, just to be more specific.
If it is a bind control that is modified from the front panel, it works fine even from remote panel. However, if you modify it through a local variable, it wont have any effect on the bound shared variable.
For this reason, all the changes made to bind indicators wont take effect on the corresponding shared variable either.
A 2nd work around is to use the property node -> value and that will affect the shared variable correctly. However, I read somewhere that we should reduce the number of property nodes to a minimum when planning to use the remote panel so updating the shared variable directly still seems best.

Trouble with console-extension using struts portlet

hello everyone,
I'm developing a console-extension for wls9.2 but couldn't get is to work despite all the documentation available. The console-ext is a struts portlet which gathers data from custom mbeans via jmx and renders the result with a jsp. What already works is fetching the data from the MBeans in the struts action. What does not work is the display of the results in the admin console. So I removed all the stuff from the jsp to just display "Hello World" which should be displayed on the desktop in the admin console, but even this didn't work (it's just a blank spot). Having a look at the log file I get the following:
e.netui.pageflow.internal.AdapterManager ERROR ServletContainerAdapter manager not initialized correctly.
e.netui.pageflow.internal.AdapterManager INFO No ServletContainerAdapter specified or discovered; using class org.apache.beehive.netui.pageflow.DefaultServletContainerAdapter

.netui.pageflow.PageFlowRequestProcessor INFO Attempting to instantiate SharedFlowControllers for request /console/ChangeManagerAction.do
ive.netui.pageflow.FlowControllerFactory INFO No Global.app was found in /console
Despite the errors it seems to find my struts config (struts-auto-config-loggingController.xm) and execute the action, but then it seems to have trouble findingd/displaying the jsp (helloWorld.jsp). I tried to set various controller-elements in the struts config, like this ([url http://edocs.bea.com/wlp/docs92/portals/integrate.html#wp1005659]source):
<controller inputForward="true" processorClass="com.bea.struts.adapter.action.AdapterRequestProcessor" />
but this didn't work either (and results in other errors). The log from above was created with a config without any controller element (since this is never mentioned in the eDocs for console extensions).
Despite spending several hours trying to figure out what goes wrong here I wasn't able to get one step closer to a solution. Does anyone have a clue what I did wrong (please ask if you need further information)? Thanks a lot!
Btw. Sorry if this is the wrong forum, I could't find another one which matches better. Feel free to move the topic to a more appropriate place. thx.
====================================
Struts config:
<struts-config>
     <form-beans>
          <form-bean name="loggingForm" type="...web.forms.LoggingControllerForm" />
     </form-beans>
     <action-mappings>
          <action path="/LoggingControllerAction"
               type="...web.actions.LoggingControllerAction"
               name="loggingForm"
               scope="request"
               validate="false"
               input="/ext_jsp/helloWorld.jsp">
               <forward name="success" contextRelative="true"
                    path="/ext_jsp/helloWorld.jsp" />
          </action>
     </action-mappings>
</struts-config>

The problem could be solved by adding the "handle" property (of type com.bea.console.handles.Handle) to the form bean.
This is stated on page 7-4 in the "Extending the admin console" guide or [url http://e-docs.bea.com/wls/docs92/console_ext/simpleext.html#wp1083856]here
In addition the following controller element must be used in the struts config: <controller inputForward="true" processorClass="com.bea.struts.adapter.action.AdapterRequestProcessor" />
This is not mentioned anywhere and should definitely be added to the guide.
Hope this helps someone encountering the same problem.

ADF UIX programatic data binding

Oracle ADF UIX Developer's Guide mentions the possibility to use the UIX framework in Java, to create new objects or alter the existing ones.
E.g. we can create a table using a construct like:
TableLayoutBean tlb = new TableLayoutBean();
The same document demonstrates the data binding:
BoundValue rows = new DataBoundValue(_YOUR_NAMESPACE, YOURNAME, "rows");
tlb.setIndexedNodeList(new DataObjectListNodeList(rows));
For "simple" attributes using DataObject DataObjectList, etc. the procedure is clear. But what about creating a data bound table or input text:
<table model="${bindings.EmpView1}" ... >
<messageTextInput model="${bindings.DeptCode}"/>
Itâs easy to understand that model="${bindings.EmpView1}" or model="${bindings.DeptCode}" are equivalent to multiple attribute bindings (data, validation, read-only, etc.), but it looks that the classes/methods resolving these equivalences and linking the bean to the corresponding DCControlBinding, are not public (or maybe I was not able to find them).
How can we obtain programmatically, in Java, the same structure as described above (in XML)? The best would be to use the same classes used when the UIX XML document is parsed to create the page description.
It would be very nice to be able to use a structure like
tbl.setModel( new JUCtrlRangeBinding(...) );
txt.setModel( new JUCtrlValueBinding(...) );
or maybe
txt.setAttribute( "model", new TextInputModelBoundValue(...) ) etc.
In JSF we can do something like:
ValueBinding vb = application.createValueBinding(value);
component.setValueBinding(attributeName, vb);
Can we do something similar in UIX?
Any help will be appreciated,
thanks,
Mircea Ionita

Since the code is already written, it's a pity that we can't use/extend it. I don't like to say it (sorry) but I find this design choice (implement the "model" only into the XML parsing layer) a little bit strange (or maybe I don't understand... ;-) ). We should (or we are supposed to) be able to do in java everything that we can do in XML.
I would like to find more support/help for the programmatic approach. I have the feeling that you are too focalised on "use-our-state-of-the-art-tools/wizards-to-write-the-code-for-you" and you forgot that this is not suitable for all projects. E.g. our application creates the user interface according to a layout defined by each user. To generate it, we need to use at maximum the extension mechanism and we can't simply relay on "rendered" attribute etc.
-When should we expect this new UIX release?
-What about the UIX controller? The Struts controller will replace it?
-What about the source code of uixexp2-demo.jar (distributed with ADF_UIX_component_guide)?
-Why while debugging we can't set a method/class breakpoint on UIX classes (to understand the data flow) - the stack is secret?
Thanks

10g: Data Binding in event handlers?

I'm trying to use data binding in my event handlers so that I can have a definitive source for the Strings that name things like this. I can see that the page is getting generated with the proper names on the elements in the page, but I always get an UnhandledEventException when I trigger the event. The idea is something like this:
        <submitButton text="Refresh" event="${ pageBean.controlRefreshEventName }" >
        </submitButton>
        <submitButton text="Hide Controls" event="${ pageBean.controlHideEventName }" >
        </submitButton>
    <handlers>
        <event name="${ pageBean.controlRefreshEventName }">
            <method class="com.avega.portlets.view.EventHandler"
                    method="handleControlFormSubmit"/>
        </event>
        <event name="${ pageBean.controlHideEventName }">
            <method class="com.avega.portlets.view.EventHandler"
                    method="handleControlFormSubmit"/>
        </event>
    </handlers>
...Now in my EventHandler I would be able to use the getXXXName methods when checking for which submit button was hit. Except I'm getting an exception instead.
(BTW, I only have the two event tags because I wasn't sure how to concatenate the el expressions with a space...)

No, there's no indication that anything is wrong until I cause the event and get the UnhandledEventException.
However, I did the an experiment with the following tags, the first in a plain JSP, the second in a UIX page, and it seems that this is the normal way of handling a non-existant bean reference. Both cases printed 'text' in the page and did not complain that 'noBean' didn't exist. It seems you get an error when you reference a non-existant property on an existing bean, but no error if the bean itself doesn't exist. Anyway, UIX doesn't appear to be any different from JSP in this regard.
<c:out value="${ noBean.noProperty } text" />
<styledText text="${ noBean.noProperty } text" />

Struts portlet redirects for outside portal

We have a standard Struts app, with many standalone pages. The idea is to wrap each page (.do) in a different portlet. Each page redirects to a validation page, and back to itself using struts.
Whe I do any redirect in the page, the browser navegates back to the page, but opening the page outside the portal.
How can I redirect correctly to the portlet?

I am using the standard redirection from struts. See above the configuration from struts-config.xml:

MVC - Performance of data binding

Hi Gurus out there
I have a concern regarding performance of (dynamic) data binding if I have a lot of <i>textEdit</i> fields containing huge amount of data on a view page.
<u>Scenario</u>:
The view page contains buttons <b>[Add textEdit field]</b> and<b> [Save all entries]</b>. If you click the button <b>[Add textEdit field]</b> then a (new) <i>textEdit</i> will be generated and the model remembers the total number of <i>textEdit</i> fields that have been generated.
DATA: textedit_count TYPE i,
      o_textedit     TYPE REF TO cl_htmlb_textedit,
      tabix(6)       TYPE c,
      binding_code   TYPE string,
      binding_str    TYPE string.
textedit_count = o_model->get_section_count( ).
DO textedit_count TIMES.
* Create a unique ID for a textEdit field:
tabix = sy-index.
CONDESE tabix NO-GAPS.
* String for the data binding of internal table model->data_stream_tab:
CONCATENATE '//model/data_stream_tab['
              tabix
              '].data_string'
         INTO binding_str.
* Dynamic data binding:
CREATE OBJECT o_textedit.
CONCATENATE 'myTextEditID' tabix
         INTO o_textedit->id.
o_textedit->width = 650.
o_textedit->height = 225.
o_textedit->_text = binding_str.
binding_code = o_textedit->IF_BSP_BEE~RENDER_TO_STRING( page_context ).
<htmlb:label for = "<%= o_textedit->id %>"
            text = "<%= o_textedit->id %>"
          design = "EMPHASIZED" />
<%-- Binding of the attribute (internal table) '//model/data_stream_tab<i>.data_stream' --%>
<%= binding_code %>
ENDDO.
Obviously the <u>whole</u> contents of the <i>textEdit</i> fields in the coding above are <u>always</u> "moved" from the web browser to the server and vice versa when the button <b>[Add textEdit field]</b> is hit every time even though the content of some <i>textEdit</i> fields haven't changed.
Does anyone have a good solution/optimization for this problem? Any suggestion, comment and/or answer will be very appreciated.
Thanks
HW

Place this code above any textedit elements you have in your page:
<script type="text/javascript">
var myFields = new Array();
</script>
Then place this code after every textedit elements, this code will get run when the page is loaded in the browser, right after your element. You are saving the ID and the default value of your element to an array. For every further element, increase the array counter by 1!
<script type="text/javascript">
myFields[0] = new Object();
myFields[0]["id"] = 'myTextEdit1';
myFields[0]["default_value"] = document.getElementById(myFields[0]["id"]).value;
</script>
Finally, include this function in your page (does not have to be at the bottom, I just put it here chronologically):
<script type="text/javascript">
function compareFields() {
for (var i = 0; i < myFields.length; ++i) {
    if(myFields<i>["default_value"] == document.getElementById(myFields<i>["id"]).value) {
    // nothing has changed, set to ignore-value (any highly unlikely value, like ")?.("
    document.getElementById(myFields<i>["id"]).value = ')?.(';
    // check against this value in your setter method
    // if this is set, then do not user submitted value to update your model attribute value
    // maybe do some output for debug purposes
    // alert(document.getElementById(myFields<i>["id"]).value);
}</script>
Now add this attribute to your submit button:
onClientClick = "javascript:compareFields();"
This should do, test it out and let me know.

Report data binding error

I have created a banded report split into departments. Each
recore has a value associated with it. The report runs fine if I
dont try to sub-total each departments vale, but if I add a
calculated field to the banding, I get the following error:
Report data binding error Error evaluating expression :
textField_2 Source text : calc.Department_Total.
Variable calc.Department_Total is undefined.
The calculated field is simply the sum of the values, with an
initial value of 0 and set to reset when the group changes on the
department. I am using the same data type for the calc field as it
automatically gave for the original Value field (Big Decimal)
Any ideas?
Dave H

Does anyone have any ideas about this, Its getting a bit
critical now. Has anyone else been able to do sums that calculate
on group changes?? The sum total works for the report, jusyt not
the bands. I desparate here, pulling my hair out.

Unable to find information on WS data binding error on WLS 9.2.03 startup

Dynamic Data Binding at runtime

For future applications, flexibility will be an important feature. One of the biggest drawbacks of forms is/was, on my opinion, not being able to create new items at runtime.
JClient will easily overcome this restriction. But how about data binding ?
Imagine the following situation: We've got a VO "order" with the "custname" incorporated as lookup data. At runtime, the user decides that she needs to see the "custloc" as well (put an additional JTextField into some whitespace on his panel). As I understand it is possible to build a view link to tie an instance of the VO "customer" to the "order" (I'd prefer that over adapting the query statement of "order" at runtime). But how can I create the new iterator binding and control binding needed to populate the dynamically created attributes with the data from "customer"? And, further on, how will I be able to make the changed configuration of my panel persistent, let's say into the DB ? Or does the data binding concept of 10g just not cover this requirement?

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

Error after creating a struts portlet in weblogic 8.1 SP 5

Hi,
I am using weblogic 8.1 SP 5, to develop an struts-portlet.
I tested my struts application and it is working fine.
I have one action i.e firstAction and 2 jsp's in my struts application.
The action just forwards to the one jsp through struts-config.
However, when i try to start the server after creating the struts-portlet i get the following error:
The source of this error is com.bea.netuix.nf.UIControlException: For portlet [portlet_1_1], could not retrieve a result for the given action [firstAction] in the given PageFlow: [null]. at com.bea.netuix.servlets.controls.content.NetuiContent.preRender(NetuiContent.java:365) at com.bea.netuix.nf.ControlLifecycle$7.visit(ControlLifecycle.java:443) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:718) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender

Context Mapping and data binding

Hi,
Please explain about the context mapping and data dinding
and also differences
Thank's & Regard's.
Sri

Hi Sridevi Sudunaguntla ,
context mapping-> means mapping between different contexts
ie suppose if we are creating a node in the component controllet and if we want to use that node in view a and view b, then we have to map this node from component controller to the required view.. this mapping of context nodes is called context mapping..for context mapping, create nodes in compcontroller.. tehn go to view-> context-> tehn drag and drop required node from component controller to the view ..
data binding-> means binding the data from nopde to the ui elements or viceversa... after the nodes are created in indudual views or after context mapping.. we have to bind these nodes to the ui elements... suppose we have an input field and we want to read that,, so we have to bind the input field to an attribute in the node.. this binding is called.. data binding.

Report data binding error unknown column name

Hi,
I am having a problem with the new 7.02 update of Report
Builder. The issue is it's not finding my SQL query.
I have wrote my query initally in the advance mode, and it
doesn't seem to reconize it. Is there an issue with this?
I did manage to fix one of my reports by using the basic mode
and selecting all my tables and seting my linkage and criteria.
I have other computers that i have not updated to 7.02 and
they do not have this issue. Below is the error:

Anyone have any Ideas??
Thanks,

Thank you very much for help.
The "Unknown column name " is a field still used in my
report, so I can't remove it.
After I clear the query in the report and reopen the report
and apply the same query back to it, I get different error message:
Element TASKNUM is undefined in QUERY.
The error occurred in : line 1
-1 : Unable to display error's location in a CFML template.
I know for sure this "Element TASKNUM is undefined in QUERY."
is defined in query. each time it complains something different. I
get really confused.
Thanks again.

I'm writing a very simple WPF app, one view. I've got a few models defined for the small handful of tables this app works with. I'm making some sort of boneheaded mistake, but I can't see what it is. I'm trying to bind to a property of one of the model
classes I've define, to a textbox in a stackpanel. Here's the XAML:
<StackPanel Orientation="Horizontal" Margin="0, 5" DataContext="{Binding cvsSpecMapping}">
<TextBlock Margin="10,0,5,0">Specimen Mapping: </TextBlock>
<TextBox x:Name="txtHl7SpecMap"
Text="{Binding HL7SpecimenTypeName}"
ToolTip="{Binding HL7SpecimenTypeName}"
MinWidth="50"
MaxWidth="100"
MaxLength="250" />
</StackPanel>
Earlier in the same XAML file I've got the following collection view source defined in the windows' resources:
<CollectionViewSource x:Key="cvsSpecMapping" />
This isn't rocket science. Here's the model class definition. I'm removing all but the relevant property:
using System;
using System.ComponentModel;
using System.Runtime.CompilerServices;
namespace SpecMapException.Models
* This class I am interested in knowing what properties change.
* Also note that the properties in this class do NOT represent all of the properties
* in the Prism.SpecimenMapping table. It only represents what this application has
* to store.
public class SpecimenMapping : INotifyPropertyChanged
private const int MAX_HL7SPECIMENTYPENAME_LEN = 250;
#region class properties
private string _hl7SpecimenTypeName = "";
public string HL7SpecimenTypeName
get { return _hl7SpecimenTypeName; }
set
if (value != _hl7SpecimenTypeName)
_hl7SpecimenTypeName = EnforceMaxLength(value, MAX_HL7SPECIMENTYPENAME_LEN);
NotifyPropertyChanged();
#endregion //class properties
#region local routines
private string EnforceMaxLength(string PassedValue, int MaxLength)
if (PassedValue.Length <= MaxLength)
return PassedValue;
return PassedValue.Substring(0, MaxLength);
#endregion
#region PropertyChanged code
* The usual property changed code.
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
#endregion
And lastly here's the relevant code which I've put into the windows Loaded event:
Models.SpecimenMapping sm = null;
private void Window_Loaded(object sender, RoutedEventArgs e)
var cvsSpecMapNames = (CollectionViewSource)(this.FindResource("cvsSpecMapping"));
cvsSpecMapNames.Source = sm;
So what is the mistake that I've made? Why isn't the data binding to the textbox txtHl7SpecMap working?
(I'm using VS 2013, .NET 4.5.)

cvsSpecMapping is a resource and not a property so you should set the DataContext using the StaticResource markup extension instead of Binding:
<StackPanel Orientation="Horizontal" Margin="0, 5" DataContext="{StaticResource cvsSpecMapping}">
Also, the Source property of a CollectionViewSource is supposed to be set to a collection:
private void Window_Loaded(object sender, RoutedEventArgs e)
sm = new Models.SpecimenMapping();
var cvsSpecMapNames = (CollectionViewSource)(this.FindResource("cvsSpecMapping"));
cvsSpecMapNames.Source = new List<Models.SpecimenMapping>() { sm };
You may also want to set a default value of the HL7SpecimenTypeName property to confirm that the binding actually works after you have done the above changes:
public class SpecimenMapping : INotifyPropertyChanged
private const int MAX_HL7SPECIMENTYPENAME_LEN = 250;
#region class properties
private string _hl7SpecimenTypeName = "def....";
public string HL7SpecimenTypeName
get { return _hl7SpecimenTypeName; }
set
if (value != _hl7SpecimenTypeName)
_hl7SpecimenTypeName = EnforceMaxLength(value, MAX_HL7SPECIMENTYPENAME_LEN);
NotifyPropertyChanged();
Hope that helps.

Report data binding error with date values

I have CF7.02 with a Microsoft Visual FoxPro 9.0 SP1 Database
that I connect to using ODBC (FoxPro Driver 6.01.8630.01). I send
my sql results to a CF Report Builder 7.02 PDF report and it works
fine. If I dump the date values before I change them, they look
like the following: {ts '2004-12-20 00:00:00'} . However I have
tried a number of ways of manipulating the date before sending it
to the report, but I continue to get errors. I don't care what
format they go to the report in, since the report reformats them
anyway. I checked to make sure that none of the dates were null.
For example <cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDateTime(#ldCFPrcInputDate#) /> yields values in the
{ts '2004-12-20 00:00:00'} format when I dump the query results to
screen. Where:
ldCFPrcInputDate = 12/20/2004
CreateODBCDateTime(ldCFPrcInputDate) = {ts '2004-12-20
00:00:00'}
ReportQuery.PrcInputDate[lcCurRow] = {ts '2004-12-20
00:00:00'}
I get the error:
Report data binding error Unable to get value for field
'prcinputdate' of class 'java.util.Date'.
coldfusion.runtime.OleDateTime -> Date
Not using the CreateODBCDate function for example <cfset
ReportQuery.PrcInputDate[lcCurRow] = #ldCFPrcInputDate# /> I
get:
Report data binding error Unable to get value for field
'prcinputdate' of class 'java.util.Date'.
java.lang.String -> Date
Here are some of my failed attempts:
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDateTime(#ldCFPrcInputDate#) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
#ldCFPrcInputDate# />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
DateFormat(CreateODBCDate(#ldCFPrcInputDate#),'mm/dd/yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(DateFormat(#ldCFPrcInputDate#,'mm/dd/yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(DateFormat(#ldCFPrcInputDate#,'mm-dd-yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
Trim(createODBCDateTime(ldtmpdate)) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate({05-07-2006}) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate('{05-07-2006}') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(05/07/2006) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate('05/07/2006')/>
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(parseDateTime('05/07/2006')) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
parseDateTime(CreateODBCDateTime(05/07/2006)) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
parseDateTime(CreateODBCDateTime('#ldCFPrcInputDate#')) />
<cfset ReportQuery.PrcInputDate[lcCurRow] = '{05-07-2006}'
/>
<cfset ReportQuery.PrcInputDate[lcCurRow] = '{05/07/2006}'
/>
<cfset ReportQuery.PrcInputDate[lcCurRow] = '05/07/2006'
/>
I also did some googling without success. Any help is
appreciated.

You may want to make sure that the column is not included in
the query variable list in your report cfr file.
The newest version of the Report Builder, which may be
installed on the server, no longer tolerates vars appearing in that
list of they are not in the query itselft.
