Netui form tag - onLoad

How can I execute some javascript when the jsp loads. Basically something like
what the onLoad would do?
-Joe

Vindhyachal,
You didn't include your checkbox tag code but I expect that you may not be
binding to the correct value which would be something like
"actionForm.checkBoxValue. I have attached code to an example that you can
play with. Remember that in page flows the form is scoped to request by
default.
If you are using 8.1 sp2 you should consider using page flow scoped forms if
you need to keep the form and its values around for more than a single
request.
I hope this example helps you.

Netui Form Tag Missing DOM Name Attribute

Without a way to specify the HTML name or DOM id of the form, you cannot access
the form in JavaScript. Both tag attributes (name, id) are already used for something
totally unrelated. Is this going to be fixed in the next service pack?
Thanks,
Troy

Netui:form in edit mode

Hi,
I am trying to use netui:form in the JSP of the edit mode like this :
<netui:form action="testAction">
 <netui:button value="Valider" type="submit"/>
 <netui:button value="Annuler" type="reset"/>
</netui:form>
but I always get the following error : Action 'testAction' is not a valid action
If I try to use netui:form tag in another JSP (not in the edit mode, for example the JSP displayed after the begin action), it works fine.
And it works fine in the edit mode with a netui:anchor tag. The action specified is called.
Here is the PageFlow Controller :
@Jpf.Controller()
public class favorisController extends PageFlowController {
 @Jpf.Action(forwards = { @Jpf.Forward(name = "success", path = "/site_unisvers/favoris/favoris.jsp") })
 public Forward testAction(TestActionFormBean form) {
 System.out.println("je suis testAction");
 System.out.println(form.getTextBox());
 Forward forward = new Forward("success");
 return forward;
Here is the portlet xml file :

Error in form submit through netui:anchor tag onClick event

Hello,
I am working on a portal application. Below is my jsp code of a simple search screen. The search parameter is customername.
<netui:form action="searchCustomer" style="form" tagId="myForm">
<netui:textBox dataSource="{actionForm.customerName}"></netui:textBox>
<netui:anchor onClick="sayHello(); return false;" styleClass="button" action="searchCustomer" formSubmit="true"> Search</netui:anchor>
</netui:form>
I have an onClick event as I want to implement some customer logic on click of the anchor tag.
function sayHello(){
// customer implementation here
document.forms[getNetuiTagName("myForm",this)].method="POST";
document.forms[getNetuiTagName("myForm",this)].action="/searchCustomer.do";
document.forms[getNetuiTagName("myForm",this)].submit();
In the searchCustomer method of the controller, the form has zero parameters. The customerName has null value.
Can anyone tell me what am I doing wrong here.
Any help is appreciated.
Thanks
Manju

I also want to add a confirm() dialog before submitting. However, setting the onClick handler overrides the one generated when formSubmit="true". I worked around this by calling the generated function directly:
<... onClick="if (confirm('[msg]')) { anchor_submit_form(getNetuiTagName('[formName]'), this.href) } return false;">
Where [msg] is the message to display and [formName] is the name of the form containing the anchor.
Hope this helps someone.

Netui anchor tag in netui:form

I have some code like following:
<netui:form action="action1" >
<netui:anchor action="action2">Check</netui:anchor>
</netui:form>
Action1 and action2 willl be finally redirected to the same JSP(for example one.jsp).
The weird thing is that: according to log output, it seems that one.jsp has been hit twice when user click "check" link.
Is it possible that when user click "check" link, weblogic not only trigger action2 but also trigger action1? forsubmit attribute is not set to true explicitly for netui:anchor tag.
Thanks in advance

hi
verify from a browser trace tool (e.g. livehttpheaders, fiddler or firebug) how many requests your browser is making. (or you can inspect the code that portal generates in the HTML). Once we have determined whether its the browser making the two requests or something on the server, we can see if there are workarounds.

Form bean with int property and netui:select tag

Hi,
I've recently started using WebLogic 8.1 for a client project. There's
been a bit of a learning curve, but I've been able to find most of my
answers in the docs or on the dev2dev site. This one, though, I've been
unable to manage.
I have a database table, call it foo. In it I have columns for id
(numeric) and name (string). I created a database control to read that
data:
select id, name
from foo
I then want to use this data to populate a select list in a form, which
is going to be used to submit new records for another table. For the data:
id name
1 Foo
2 Bar
3 Bletch
I want to generate a select list (this is the output HTML, not the netui
tags):
<select name="foo">
<option value="1">Foo</option>
<option value="2">Bar</option>
<option value="3">Bletch</option>
</select>
My first question is what the best way to do this is. I was able to get
this working by creating a database control, which returns an array of a
custom Foo class. I then pass that array into a utility method which
converts it into a Map, and pass that map to the netui:select tag in the
optionDataSource attribute. This works, but it seems rather roundabout,
so I'm wondering if there's a better way to do it, without needing the
conversion utility method in the middle. I tried playing around with
the control, I tried using different netui tags (I thought I could do it
with a repeater and netui:selectOption tags, but that didn't work), and
nothing else worked.
The second problem arose when I was tying the result to a Form Bean. I
created a bean with all the data that I was reading from the form, and
at first, I just made everything in the form bean be a String. For this
select, though, the values are ids, so I thought I'd just make them be
ints in the form bean instead. However, when I did that, WL decided
that it wanted to add in a default option with a value of 0:
<select name="foo">
<option value="1">Foo</option>
<option value="2">Bar</option>
<option value="3">Bletch</option>
<option value="0" selected>0</option>
</select>
I've tried to find a way to get rid of that 0, and I can't. Is there a
way to prevent it from sticking in a default value like that? Or do I
have to just leave it as a String in the form bean to get it to work the
way I want?
Thanks in advance for your help.

wrt your 2nd problem, in the jpf, for the form bean, are you declaring your id
like this:
private int id;
if so, try declaring it w/ a valid value, like:
private int id = 1;

Netui: anchor tag with target attribute.

I am using the netui:anchor tag inside an iframe to post to an action. But the
resulting page is displayed within the iframe. Will the target attribute of the
netui:anchor tag help solve the problem. What is a valid value of the target
attribute.
thanks,
Shankar

does the action have a formSubmit = true? If not then your modal dialog should be shown via the onclick and you have to javascript the link click (based on your modal dialog options)
If you do have a formSubmit=true, then you'd have the onclick show the modal dialog and you would have to write additional javascript to submit the form (Along with setting its action)

Set selected in netui:select tag

Hi, all
I wonder how to set the selected item after come back from server. I have
--- jsp
<netui:select dataSource="{actionForm.personStr}" optionsDataSource="{actionForm.personOptionsHashMap}" defaultValue="-- select one --">
--- server (.jpf)
form.setPersonStr(form.getPersonStr());
form.setPersonOptionsHashMap(hashMap);
So when screen come back, it has selected duplicated at bottom of the selection. Is there a way like normal html select behavior ?
Thanks inadvance for any inputs.

Murthy,
Unfortunately, though a very reasonable requirement, there is no option for
placing the default item.

Hi,
I am using <netui:select dataSource="{actionForm.xyz}" defaultValue="Any"optionsDataSource="{actionForm.someMap}"
/>
Now I am getting the values from database to populate the dropdown usingthe optionsDataSource.
As I am using the defaultValue, it is being added to the end of thedropdown and
selected by default when I a mopening the page on browser.
In my dropdown, the values are as follows:
apple
orange
banana
Any
Now my requirement is, the defaultValue, Any, must be there at the top ofthe
list instead at the bottom of thge dropdown values. i.e., In the abovelist, "Any"
must be above apple option.
How can I achieve this using netui:select tag?
Thanks & Regards,

netui:content tag not outputting values

I am trying to output some data using the <netui:content tag in a page flow. I have a form that calls a controller which then calls a jsp. I've tried numerous scopes and all of them behave the same:
-- Controller Code Snippet:
// FOR PAGE FLOW SCOPE 
this.participant = participant; 
// FOR SESSION SCOPE 
getSession().setAttribute("participant", participant); 
// FOR REQUEST SCOPE 
this.getRequest().setAttribute("participant", participant); 
-- JSP CODE -- 
// FOR PAGE FLOW SCOPE 
PageFlow: <netui:content value="{pageFlow.participant.getCardAccount().getStatus()}"/>
// FOR SESSION SCOPE 
Session: <netui:content value="{session.participant.getCardAccount().getStatus()}" />
// FOR REQUEST SCOPE 
Request1: <netui:content value="{request.participant.getCardAccount().getStatus()}" />
-- Resulting HTML -- 
PageFlow: {pageFlow.participant.getCardAccount().getStatus()} 
Session: {session.participant.getCardAccount().getStatus()} 
Request1: {request.participant.getCardAccount().getStatus()} 
-- Only solution that works so far -- 
<%Participant participant = (Participant) session.getAttribute("participant"); %> 
<%=participant.getCardAccount().getStatus()%> 
I am new to portal, so I must be missing something very simple. Any help would be appreciated

Hello
If you want to show the subvi values in main vi front panel while subvi is running, you will have to pass references to front panel indicators to the subvi . Search "references" in labview examples to learn how to use them.
If not, the from panel indicatos will be updated when subvi stops running.
Hope it helps

Netui Anchor Tag

Can we use href and action attribute in netui:anchor tag both at a time...*href* is for opening a modal dialog and action is page flow action

does the action have a formSubmit = true? If not then your modal dialog should be shown via the onclick and you have to javascript the link click (based on your modal dialog options)
If you do have a formSubmit=true, then you'd have the onclick show the modal dialog and you would have to write additional javascript to submit the form (Along with setting its action)

Netui:select tag

Hi,
I have a netui:select tag. When the user selects an option, I want it to execute
the form's action (instead of having users to click a submit button).
How do you do this?
Thanks
Laxman

Hi,
I think you can add a submit() javascript to the onselect action of the
select tag. When the user selects a value the form will be subitted that
means the form's action will be executed.

Netui:fileUpload tag ???

Does anyone know how to use the netui:fileUpload tag. When I try to use it I get
the error:
NETUI ERROR: Unable to update expression "{actionForm.theFile}" with the value
[CHANGES.txt]. The typical cause is that the object represented by the expression
is not available or is the wrong type for updating.
I set the "accept" attribute in the netui tag field, which I think is a very bad
idea since I want to upload any type of file. I don't want to specifiy a mime
type. So I tried a specific one then the octet-stream one. The JSP page when
displayed doesn't even change when you set the "accepts" attribute.
I had this working in 8.1 beta going around the form posting and using the O'Reilly
classes but 8.1 GA blows up now. So I am trying to use the netui tags but I get
the error above.
Any help??
Thanks.

Raj,
Thanks for the files but they don't have anything in them refering to the file
upload. They don't have any custom code at all. I think you sent the wrong files.

Netui:form and netui:hidden/textbox/... required datasource

Hi all,
1) Question
Can I set the value of the netui:hidden tag different from the field to
which it will post it's content?
because datasource both defines the data to get and set to, which makes
dynamicaly generating a form in a loop seem impossible.
2) Problem illustration
In a jsp of a pageflow in Portal 8.1 I am iterating through an n-size list.
How do I dynamically generate a form for each item in the list?
How does the datasource attribute actually works?
<%
List bookList = (List) session.getAttribute("bookList");
<table>
<%
Iterator it = bookList.iterator();
while (it.hasNext()) {
BookTO book = (BookTO) it.next();
pageContext.setAttribute("book", book);
%>
<tr>
<td>
<netui:label value="<%=book.getName()%>"/>
</td>
<netui:form action="viewBook">
<netui:hidden dataSource="{book.isbnPK}"/>
<%-- Generates a NETUI ERROR when
clicking on the button (not before) --%>
<td>
<netui:button value="View"/>
</td>
</netui:form>
</tr>
<%
%>
</table>
It places the isbnPK in the form without any problems,
but when submitting the form it generates this error:
NETUI ERROR: Unable to update expression "{book.isbnPK}" with the
value [1-56592-403-7]. The typical cause is that the object represented by
the
expression is not available or is the wrong type for updating.
The BookForm and the BookTO have these methods though:
public String getIsbnPK() {
return isbnPK;
public void setIsbnPK(String isbnPK) {
this.isbnPK = isbnPK;
And in the pageflow:
protected Forward viewBook(BookForm form) {
Thank you for any and all help,
Geoffrey

Figured it out.
One of the other portlets on the page had a refreshAction property set to call the begin() method for that portlets controller when the page is refreshed. It was trying to accept the multipart form data sent from the other portlet and obviously wasn't set to accept multipart data. Removing the refreshAction property fixed the problem.

Netui:repeater tags with ranges (aka prev/next)

Is there some way to implement ranges using the <netui:data-repeater> tags? By
ranges, I mean where you have 123 items in a list and you only display numbers
1-50. Clicking NEXT would give you items 51-100. When you're there, clicking PREV
would take you back to 1-50.
Sample code would be nice. I think it could be done with the <netui:data-choiceMethod>
tags, but what I am envisioning would be pretty ugly

I am still stuck. I have the pager working fine. But, I have a checkbox that needs
to be bound with the recordid. When the form is submitted after selecting records
on multilple pages, I want to retrieve the recordids of records that were checked.
How do I do that? A chckbox datasource can only be a one-value String property
of a form. But, I need to save an array of ids that were checked. I am so lost.
Please help.

Here's an example of implementing a paged repeater.
Briefly, here's how it works:
The entire data set (a Product[]) is stored in the JPF. When paging
through this data set, a
sliding window (also stored as a Product[]) is used to contain the "current"
set of products to
render in the page. The sliding window Product[] is of size PAGE_SIZE.
When transitioning between
pages, this window is recalculated for each page.
Also calculated are the "currentPage", "lastPage", "prevPage", and
"nextPage", which are used to
render a pager like this:
Page <currentPage> of <lastPage> <anchor to prevPage> <anchor to
nextPage>
The JPF and JSP are pretty well documented. To run the Page Flow,
drop the JPF and JSP into a
directory called "repeaterPaging" in an 8.1 SP2 webapp.
There are lots of other ways this could be done (and certainly some
that are more efficient :),
but hopefully this helps get you started.

Yep, I did promise that, and nope, it hasn't been done yet. :)
But, thanks for calling me on it.
Will try to do that and distribute it to the list in the next fewdays.

Did you ever get a chance to put one together? Would really loveto
see it if
you did.

We're talking about adding a pager to the repeater in a future
release of Workshop, but I don't believe that it will appear inan
8.1
service pack.
Additionally in 8.1, we are not exposing a NetUI tag SDK.
That being said, it isn't that difficult ot build a pager from
scratch with the <netu:anchor> / <netui:parameter> tags and a little
code in a JPF.
You'd want to have "prev" and "next" actions in the JPF to which
anchors in the JSP are bound. Then, you can keep track of the "current"
page in the URL and build the previous and next page indices fromthe
value that is availble in the request. Finally, create an intermediate
data structure that contains the data to display in the "current"page
and bind the repeater to this data structure. You'd build the contents
depending on whether the prev or next links were clicked. For example,
if your data set has 100 items in it and you only want to displayitems
20-29, you'd be on page 2 (depending on whether you start countingat
0 :) and the intermediate list would contain exactly these items.
Might sound complicated, but I think this would work out prettywell.
Hope that helps...

If not, is there a way to build on the netui:taglibs to extend
their
functionality?
I know the grid has paging functionality but it ties you to rowsetsfor input, whereas the repeater is much more flexible.

* Implement data set paging. This method uses a simple _page paramater
on the URL
* to indicate the correct "page" to display when "Prev" or "Next"
are clicked
* in the JSP. The key principle at work here is a sliding window
of size PAGE_SIZE
* that is moved forward and backward through the complete dataset.
This window
* contains the set of items to render for a single "page" in the
repeater. As
* the current page changes, this window (an array of size PAGE_SIZE)
is
* reconstructed.
* The pager consists of three parts:
* - a simple "Page # of #" label
* - a previous anchor that is enabled when there is a previouspage
* - a next anchor that is enabled when there is a next page
* To render a "page" of data, the _page parameter is convertedfrom
a String
* to an int. Using the page integer, the start and end of a window
into the
* complete data set is calculated. This windows slides back and
forth along the
* data set in PAGE_SIZE increments depending on the value of the
current page.
* In this case, with a PAGE_SIZE of 5 and data set size of 17,the
possible windows
* are:
* products[0] -> products[4]
* products[5] -> products[9]
* products[10] -> products[14]
* products[15] -> products[16]
* Thus, the lastPage value is 4, which is calculated with the Math.ceil(...)
* call below.
* Given the start and end of this window, a temporary array ofsize
PAGE_SIZE
* is created to hold references to the items that should render
from the complete
* data set. This array is passed to the page as a JPF page input
and is rendered
* with the <netui-data:repeater/>.
* Finally, four additional values are made available to the page
in the request
* and are used to render "Page # of #" and to provide parameters
to anchors that
* will display the previous and next pages:
* - Page # of # -- the first # is "currentPage" and the second#
is "lastPage"
* - prevPage -- the int value of the previous page. If there is
no previous page,
* this value is null in the request
* - nextPage -- the int value of the next page. If there is no
next page, this value
* is null in the request.
* Notes:
* - In order to have multiple repeaters on a page operating independently,
* the "_page" parameter would need to change to include a namespace
that
* would be used when finding the current page for a data set.
* - This JPF is implemented with a single "page" action that performs
both
* next and previous paging. This could also be implemented with
"prevPage" and
* "nextPage" actions that implement additional logic that runs
on the previous
* and next transitions.
* - No real error checking is done to ensure that the PAGE_SIZE
is greater than 0.
* Handling errors:
* - If parsing _page from the request fails to convert to an int,
a NumberFormatException
* is shown in the console and the first page will is used.
* - If the current page value is greater than the number of pages,
the last page will
* be displayed.
