Forms - Input field larger than VARCHAR2(4000)?

Maybe I'm confused, but it doesn;t seem possible to create a form with a field larger than VARCHAR2(4000) with the builder - if you choose CLOB or LONG for a field type in the Database Object you want to use with your Form, the form builder doesn't display that field.
So how do I make an input field that will accept a large amount of character data?

It's a limitation, this is not been fixed until release 10.2.0.x.
quota readme.txt:
* Binding more than 8000 bytes data to a table containing LONG
columns in one call of PreparedStatement.executeUpdate() may
result in an ORA-22295 error.

  • Adobe Reader crashes on importing form XML data larger than 500KB

    I'm trying to import XML data into a PDF form using Adobe Reader. When the file size of the XML is smaller than 500 kilobytes, the PDF form loads the data fine. However, any larger than this leads to Adobe Reader crashing without a warning or error message.
    I've tried this with Aodbe Reader versions 7.0.5, v9 and even the latest Adobe Reader X: same result. So the latest version does not have any patches for this issue so far.
    To be more specific, the form is an IPC-1752-2 v1.0 Material Composition Declaration form. The XML data is generated by a software. Some of the XML files worked fine but others caused Reader to crash. Experimenting with a repeating data node, I tried different file sizes and came to the conclusion that Reader crashes past around 500KB.
    Any patches or quick workarounds will be greatly appreciated!
    Thanks,

    Firstly I woudl not use the submit by email button (it is too restrictive). You could create or build an email submit button. Just drop a regular button on the form (change the caption to something more meaningful). Now make it a submit button. A submit tab becaomes active. Click on that. In the Submit to URL field enter in the command:
    mailto:[email protected], youremail [email protected]?subject="This is a subject"&cc="ccaddress if req"&body="This is the body if required"
    You can control all parts of the message this way. Do a google search for mailto to see all of the different options.
    Now you need to set what you are going to send. In the Submit As dropdown, choose PDF. Now a PDF will be sent. To be able to allow all users to send PDF you will have to Reader Extend the form. You can do this in Acrobat. Once all of this is done, open the form in Acrobat and under the Advanced menu choose Extend Features in Adobe Reader. Now follow the wizard and save your form. Distribute the saved form.

  • Checking an Array with a form input field to return true or false?

    I have an array that when dumped, lists dates for all days of the month. There is a form, where the user specifies the date and when submitted, transfers to a processing.cfm file which is where i want the <cfif> to check if the date specified in form exists in the array (this way, it only limits the user of only being able to select a date from this month for an event). Is it possible to have a cfif where it will check whether or not the array contains the date the user has specified and the return true (if contains the date specified), and transfers the form to email.cfm (where it will email all the form inputs) or will return false (if outside that range) then return back to the eventform.cfm?

  • Placing variables from db table in div vs form input fields

    Hello,
    Because of all the help I've received on this forum, I'm getting comfortable with reading data from db tables and writing back to them.
    Recently I've needed to create an "update" of a form (no refresh) where
    1 -  the data are read in from a table to a form
    2 -  the form data are changed by the user, and
    3 - the data are written back to the table.
    To do this, I've learned about parsing and displaying returned json data from a "success" under ajax.
    Here's a "mini" example of what I've learned:
            success: function(result)
            $('#loadmehere1').html(result['localid']);
           $('#inload1').val(result['localid']);
           error : function() { alert("error"); }
    });//End of ajax call
    So with my experimentation, I've found that ".html" is used to fill a div, and you have to use the ".val" to fill an input box on a form.
    My questions are:
    1. Can you point me in the right direction to learn about why an input statment needs a ".val" and a div can take an ".html"?
    2. Would you populate divs and input statements with different commands?
    Thanks very much!

  • Input field validation in a Table based on the value of other column

    Hi all
    I have a table with 2 columns. column1 is of text view and  column2 is Input field.
    The user should not be allowed to enter a value  in the column2 ( input field) greater than the value populated in column1(textview).
    So for Eg; if the column1 is populated with value 100, The user should not be able to enter a number greater than 100 in the column2  input field.
    Please let me how this can be achieved.
    I appreciate the help.
    Thanks

    Hi,
    Let me make sure u r working with table control.
    First u have to create a event(VALIDATE) to do the validation.
    Inside the event,
    1. First get the current index where user has pointed the curson
    2. Once u get the index read the internal table with index value.
    3. Now u can compare the col1 and col2 values and populate the error message.
    1. DATA : lo_elt TYPE REF TO if_wd_context_element,
                   l_index type i.
    lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
         CALL METHOD LO_ELT->GET_INDEX( RECEIVING  MY_INDEX = l_index.
    above code should be written inside the event.
    Thanks,

  • Cursor not appearing in password input field

    Hi All,
    I know this is probably going to be a bit of a long shot but i have got two fields on the front screen of my web dynpro for abap, with the second field set as a password field.
    When I tab through the fields the cursor apears in the first field but when I press tab again to move to the second password field, although it highlights the field the cursor does not appear so I cant start typing without actually using the mouse to click in the field!
    If i place the password field first or make it a normal input field rather than a password field this problem goes away but obviously these are not valid solutions to this problem.
    Any ideas would be much appreciated.
    Mart
    P.s. i am not 100% certain about this and not sure if it will help with a solution but i believe this bug has only surfaced since we upgraded to the lastest patch level!

    Hi All,
    Before I raise a support ticket with SAP I was just wondering if anyone ever found a solution to this problem. Have managed to put off finding a solution for as long as possible:-( Only solution i have find so far is to capture the user pressing enter and then passing the focus onto the password field but this is not great as the user has to press enter instead of tab which is not particulally intuative.

  • Want the data store values to be displayed in input field of form

    Hi,
    I wanted to know wether is there possibility of displaying the data in a input field instead of expression field.
    In our model i have used a form which has material type,plant and Vendor connected to data service1 in turn gives the out put in chart and i also have the second input form which has To(0CALMONTH) combo box which is connected to Data service2 and gives the data in table.
    But what i wanted is to i also want to use the input fields of first form to second Data service2 and get the data based on on inputs of form1 and form2i.e also To field.
    We can connect the port from form1 to DS2 but problem is we need to click the submit of form1 and form2 and it doesnt gives the output according the input of form1 and form2 as it gives the output of that form when we click that submit button.
    I have followed help.sap for data tore procdure.
    So i have used a datstore where i will store the values of form1 and call it in expression field which i will add and hide it in form2(hide because user should not see that input fields).
    Formula used in data store for expression field.
    IF(CONTAINS(STORE@matltype,@Material_Type),STORE@matltype,STORE@matltype &(IF(LEN(STORE@matltype)>0,'; ',''))&@Material_Type)
    But whats happening is the value is getting concatenated when i goon change the values in input field, so i wanted to get the values to be replaced as soon as i change input field of form1(if  use replace function its not working) and also it would be more preferrable if we use input field instead of expression field.
    I would also like to know is there any alternate solution for the above requirement instead of datastore.
    Thank You
    K.Srinivas

    Hi,
          I have Form1 connected to Data service1 displays the data in a Chart and i have another Form2 connected to Dataservice2 displays the data in table.
    In form1 there are Material Type,plant, and Vendor and form2 i have To (0CALMONTH)SO now i want also Form1 inputs for Table which gets teh data from Dataservice2.
    What i have said earlier is connecting Form1 to Dataservice doesnt fetch the data correectly,its because if i click submit in form1 i get the data of those 3 inputs and i need to click the submit button in form2 after giving input which shows the data accordingly where it doesnt fulfill the requirement.
    So i wanted some solution for that.For that reason i have used the data store and the procedure i have followed the help.sap as i said in my above mesage.
    If Data store is also suggestable than i want to display the data in Text input Field  instead of Expression field which should replace the previous values as soon as values change in data store.
    Hope i have tried to be clear if still it is not i am ready to explain again.
    Thank You

  • Is there any way to store data larger than 4000 bytes?

    Hi,
    Could someone here know which data type to store database column size larger than 4000 bytes.
    VARCHAR2 has the limit of 4000 bytes in database column. Is there ways to store data larger than 4000 bytes?
    Thank you very much!

    CLOB
    You use the CLOB datatype to store large blocks of character data in the database, in-line or out-of-line. Both fixed-width and variable-width character sets are supported. Every CLOB variable stores a locator, which points to a large block of character data. The size of a CLOB cannot exceed four gigabytes.
    CLOBs participate fully in transactions, are recoverable, and can be replicated. Changes made by package DBMS_LOB can be committed or rolled back. CLOB locators can span transactions (for reads only), but they cannot span sessions.

  • Changing the size of text input field in xml style coldfusion forms

    Does anyone know how to get the size attribute of a text
    input field to work in a coldfusion xml form?
    Example: When I enter the following code and view the form in
    a browser, all of the fields are the exact same size.
    <cfform format="xml" name="testingform" method="post">
    <cfformgroup type="horizontal">
    <cfinput type="text" name="first_name" size="10"
    label="First Name">
    <cfinput type="text" name="middle_init" size="2"
    label="Middle Initial">
    <cfinput type="text" name="last_name" size="20"
    label="Last Name">
    </cfformgroup>
    </cfform>

    Indeed a mistake in the Coldfusion engine. Or is there some
    reason for it? In any case, you should report it.
    Look in the source, and you will see why it happens. The XML
    form makes use of the stylesheet
    /CFIDE/scripts/css/default_style.css. There the width attribute is
    hard-coded for the cfinput element, thus
    .cfInput, .cfTextarea {
    font-size: .8em;
    font-family: inherit;
    width: 200px;
    I would replace that block with
    .cfInput {
    font-size: .8em;
    font-family: inherit;
    .cfTextarea {
    font-size: .8em;
    font-family: inherit;
    width: 200px;

    Hello,
    you need to provide the information via the interface, which you create for the Adobe form.
    And then pass this values via the following function module inside your generation report.
    CALL FUNCTION fm_name
    check standard report : FP_EXAMPLE_01 as an example!
