Gatewayed Portlet ignoring Form Items

I have a rather simple form with an Infragistics Web Control on it. The Portlet works as needed when NOT gatewayed. When Gatewayed the Portlet works as far as interactiveness and display etc. When I do a POSTBACK the only object making it back to the Remote Server is the ASP.NET viewstate, the object (UltraWebGrid) viewstate is ignored, I have tried using the ptrender tag as a last resort, it does nothing. When examing the Trace.axd file I see that the object has no ViewState being passed back, under the Form Collection Object Header. I wonder if anyone has had any experience with this sort of problem?
Thanks.

Carolus,
You have found the problem here. It looks like your control is trying to call the __doPostBack function on the form - which no longer exists if the form is a portlet. This is because there could be more than one form on the page and in this case the window.__doPostBackwould not know which one to get. Even worse here is that the code here actually tries to replace the __doPostBack function with it's own code (igtblGrid) - I don't know what it tries to replace it with but I'd bet it's not gonna keep you in the portal! So the short story is this control is not going to work with the web controls.
Basically you can do a few things here.
Fix the UltraWebGrid so that it behaves nicely - i.e. not try to completely steal control of everything & also handle forms based upon the portlet id so there are no collisions (unless you implement a javascript switching technique so that the __doPostBack calls the one you want). You may be able to do this by modifying it's JavaScript, but I expect this will be very difficult & may be against their terms.Abandon in-page refresh. Either open this control in a popup or gatewayed/hosted mode - in either case you probably don't want to use the EDK Web Controls at all.Use a more simple Grid - the standard DataGrid should work - I'm not familiar with this UltraWebGrid so I don't know what extra features it gives you, but you may also be able to extend the DataGrid to support them.Find another 3rd party control which does have the required features and does work - I don't know of any though so don't ask me!Use our JS controls. Check out the table control in the samples - it's a reallynice control, but beware, it's not yet supported.I am sorry that this doesn't work however you can see that with code like this control supplies it really is impossible to support all 3rd party controls.

Which Forms Item properties are converted to APEX?

Has it been documented which Forms item properties are converted to APEX with the Application Migrations tool?
For instance the 'required' property will be converted, but item properties like 'format', 'initial value', 'hint', 'tooltip', 'auto hint', 'justification', 'case restriction' and 'max length' are ignored
I hope more Forms item properties will be converted in a next APEX release.
Regards,
Mathieu

Hello Roel,
Thanks for the suggestion. I have read that piece of paper, but it doesn't tell you in detail what item properties are converted.
I would have liked for instance that the "hint text" property is converted into a help text for a page item.
If the auto hint or tooltip is set in forms, than the Template label of a page item should be set to optional/required with help.
and so on...
There are more item properties which could have a destination in APEX, I reckon.
Now it's difficult to tell which are and which aren't converted.
As soon as you have this kind of list you know which post configuration actions you have to perform.
regards,
Mathieu

How to update a report from a form on the same page when form item changes

I have a portal form from a table and a portal SQL report with a bind variable on a page. I want the report to get updated with details based upon what was selected from a form item. The form item is a selection from a dynamic LOV. Whenever the form item gets changed, the report should get updated to reflect the change. Can this be done using a javascript ONCHANGE event?
Oracle Portal Version is 10.1.2.2.0.

Your applet can open an URLConnection and read directly a document from your webserver.
public String readText() {
java.net.HttpURLConnection conn = (java.net.HttpURLConnection)myURL.openConnection(); ...
}So using JavaScript on your page, you might call readText() to fill that textarea.
The interesting link you gave, handled the JavaScript/Applet interaction. Test that with just return "Hello";.
The real programming is more interesting.

Getting a form item to load first in target page

according to ben forta who i met many years ago, cf loads the complete page and then does functions in a particular order. i.e. includes, queries, etc.
my problem is that i am sending over a unique identifer in the formset that is needed in an include on each page of my cart (i don't use cookies or sessions and don't want to get into that).
what i want to know is if there is a way to force cf 10 to look at form. items first. the page needs that number or the include (header.cfm) crashes.
i also have that issue with cfabort where cf does a lot of functions before it recognizes that tag which can really foul up things if a variable isn't there.
site needs to be pci compliant
tnx in advance,

I receive no errors as stated in the original post.
Eventually the webpage does load, but it takes 2 minutes for anything to start happening.
During that time, the program is responsive, but displays no errors or status messages.
This happened in Firefox version 6, as it did for the other poster in this thread.

Beginners question - making sense of form, item, pane & variable (with relation to where data is stored in the SQL database)

Hi Everyone,
I am new to writing reports (SQL code) for SAP, however I am aware that inside SAP Business One it is necessary to enable System Information (from the View menu) in order to see which tables (and related table attributes / column names) are related to various aspects of the various SAP 'modules' (e.g.: A/R Invoice).
Using an A/R Invoice as an example I can see at the row (or line) level that an item with the description of 'Opening Balance Transfer' is contained in the table INV1, within the attribute (or column) called Dscription.
However not every 'on screen object' shows a table / attribute. For example in the same A/R Invoice if I hover my mouse over the Balance Due field all I see is Form related information.
My question is 'How do I make sense of the Form, Item, Pane, Variable information?', with relation to where data is stored within the SQL database?
Links to online tutorials explaining how this feature of SAP Business One will be much appreciated, along with any personal advice regarding working with this information.
Any (and all) help will be greatly appreciated.
Kind Regards,
David

Hi David,
1.Here I am explaining use of each field except pane
a. Form ---> Used in additional authorization creator
b. Item, column--->Useful in creating Formatted search queries (FMS)
c. Variable --> Some of the field values based on another values. ie. indirect values.
d. INV1---Table name
2. How to get variable?
As per your second attachment, to get balance due ,you need doc total field from OINV table. For example,
SELECT T0.[DocNum], T0.[DocTotal] FROM OINV T0 WHERE T0.[DocNum] = 612004797

How to identify listeners types for forms, items and events in addon wizard

Dear users,
I have developed a sample addon through B1DE wizards and successfully installed and connected the addon and can view menu and form of my addon. Since i am new to this, i didn't add any listeners to my form, items and events because i don't know what type of listeners to add and what coding to add after adding listeners.
If anyone describe me how to work with listeners, i would be glad. My form has basic fields like BPcode, BPname, Docnum, Itemcode, Item name, quanity, price, total etc. Uptil now my addon form has no function of getting list of BP and Items and calculating the totals based on price and quantity but it has some basic functions like add, update,del, add print view, next record previous, record next etc. which are due to object registration and auto-code generation wizards i think.
Please help me in adding listeners and their relevant coding.
Thanks in advance.

Thanks for reply, Actually I am asking about listeners in the wizard of B1DE, code generator wizard. I think you are telling me about adding listeners directly in the vb.net. Kindly, tell me first, what event type I should add for item, form etc while adding listeners during the wizard. Or If you know some link where event types of listeners are decribed, you are more than welcome.
Thanks,
Farhan

How to fetch the value of tabular form item in javascript

Hello all
I want to do some calculations on the value entered by the user in the textfield of a tabular form, how can I fetch the value of tabular form item in the javascript?
I am using normal tabular form, not using apex_item tabular form.
I can pass the current textfield value to the function using "this" as a parameter, but how can I fetch the value of other rows of that same column?
Thanks
Tauceef

Hi Alistair
jQuery is still not working, but I got it done through some other means, this is the code:
function total(pThis){
var l_Row = html_CascadeUpTill(pThis,'TR');
var l_Table = l_Row.parentNode;
var l_Row_next = l_Row;
var n_rows = l_Table.rows;
var lInputs;
var v1;
var sum = 0.0;
var temp;
var i = 0;
var j = 0;
//alert(n_rows.length);
while(j < (n_rows.length - 1))
temp = 0;
if(l_Row_next != null){
lInputs = html_Return_Form_Items(l_Row_next,'TEXT');
v1 = lInputs[0].value;
//alert(v1);
sum = parseFloat(sum) + parseFloat(v1);
l_Row_next = l_Row_next.nextSibling;
temp = 1;
if(temp == 0){
l_Row_next = l_Table.getElementsByTagName('TR')[1];
lInputs = html_Return_Form_Items(l_Row_next,'TEXT');
v1 = lInputs[0].value;
sum = parseFloat(sum) + parseFloat(v1);
l_Row_next = l_Row_next.nextSibling;
j= j+1;
$x('P78_TOTAL').value= parseFloat(sum);
I am calling this function onblur event of the textfield.
Still I am having one problem, I want to perform this calculation on load of the page also, how can I do that? because while calling onblur of the textfield I can pass that textfield to this function but on onLoad how I will pass the textfield to call this function so that I will be able to get the textfield value in the function?
there may be some rows already existing, so I want the total of the existing rows to be displayed in my P78_TOTAL textfield that is why I need to do this calculation on onLoad of the page.
Thanks

Need to send form item inline of an email

Hi,
I need to send an email with a form item that would send REQUEST and submit a note to a database table text column.
an email with an HTML form w/ submit button..
Is there a link to a HOW TO ?
Thank you, Bill

Hi, Thank you for the link but I already send email in my app....
I guess the real question is:
when sending an email from with in the app, how do you build the syntax to have a button with in the email to take the receiver of the email into the app...
or in the email have a comment textarea and a button
When the email user clicks the button it sends the textarea to the app and updates it.
how do you make it so if the request comes from the email you don't need to logon?
As I typed this I kinda am getting ideas... just to build a form within the email but it is the ? form action line I need to know how HTML_DB needs the syntax to be...
Clear as mud?
Thanks Bill

Hi,
Country-Specific Fields: China, Korea and Japan
Primary Form Item
This field appears:
1) In the drop-down list that contains all the active primary form items
2) Only if the G/L account determined is a cash flow relevant account
After defining the cash flow line items in the Cash Flow Line Items - Setup window, specify the primary form line item that is assigned to the cash relevant transaction from the APA Cash Flow Assignment window.
Note
You can change the cash flow line item:
1) After the payment is executed, unless the payment is a credit card partial or split payment
2) At a later stage, in the corresponding journal entry or original transaction, unless the transaction has been cancelled
Check if the details and the defination are there under the following path:

How to validate htmldb_item form item

I have a multiple row form item using htmldb_item.text ( so that a user can enter a quantity for that row item ).
How is validation best handled to ensure that a value is entered for that row?
note: there is also a htmldb_item.checkbox on the row that the user checks to flag that an operation should be done.
Thanks as usual
Bill

for what this is worth:
as scott said, only checked values are passed through from htmldb_item.checkbox'es over to the htmldb_application.g_fNN arrays. that's just how conventional web checkboxes work. if you want to keep your checkboxes in your form, just do their processing in a separate loop. if you're having a hard time keeping the values of your checkbox array matched up with the other htmldb_item values from their corresponding rows, just make sure your checkboxes return values you can use to identify your checked rows. so if you were going against the emp table, i'd suggest having your checked values return EMPNO's...
select htmldb_item.checkbox(1,empno) c from emp
...that way you could more easily match those empno's up with your other htmldb_application.g_fNN values during your page processing.
hope this helps,
raj

Multiline text in form item

Hi,
I am having the following issue. I have a form with several
items, each of them containing a Text element. When the text is too
long, the text element wraps the text in a second line, but the
form only shows the first line. The curious part is that the form
item's height do increase, but the extra space is shown blank. Any
idea on how to correct this problem?
thanks.

Try giving it a pixel width instead of a percentage.

Reports Portlet Parameter Form LOV Format

Hi,
I have created several LOV's that I want to use in the Reports Portlet Parameter Form for running Oracle Reports, but the format I am choosing when creating the LOV's is not showing correctly on the parameter form. I am picking 'Check Box' and 'Radio Group' for several of the LOV's, but they are still displaying as Dropdowns on the parameter for. Am I doing something wrong here, can the parameter form show check boxes and radio buttons?
Thanks

hello,
i am afraid the answer to both questions is 'no'. i would suggest you create some HTML/JSP parameter forms for your reports. the parameter form editor of reports is very limited and for more complex requirements we suggest using other tools (or the JSP web source of reports, which is available from 9i onwards).
thanks,

Disabling the 'Schedule' tab on the Reports Portlet Parameter Form

Hi,
I have deployed several Oracle Reports through Portal using the built in Reports Portlet Parameter Form and I was wondering if anyone knows how to disable the 'Schedule' tab located on this form. I would like users to run the reports but not to schedule them.

I forgot to say that, the reports is an XML report .

Hi.
I am facing a problem with the parameter form in reports 10g. The number of parameters in this report are huge. After designing the parameter form , i save and close the report. Now if i re-open the report to do changes, the width and height of the parameter form is reduced (which i increased changed previously) and if i click on any field , that specific field is repositioning itself inside the (reduced)border lines.
I request the forum to give a remedy on this issue.
thanks in advance

Dynamically adding form items

Hi All,
I am facing problem while adding the form items to the form
dynamically it get distorted and form items not in proper
alignment.This issues is resolve when i revisit the same page
again.
Thanks, in advance.

Notice that using array index "i" screws up the formatting of your post. It makes the font switch to italics! Anyway...I think what you want to be doing is this:
String[] s={"a","b","c"};
for(int j=0 ; j<s.length ; j++) {
JButton b = new JButton(s[j]);
this.getcontentPane().add(b);
