Making a field as read-only using Forms Personalization.

Question

Hi All,
I have one requirement.I developed one form which is used to display Customer related Information.Some fields are created under one block and "reason-for-write off amount" field is created under another block.I have created Master-Detail relation for these 2 blocks.If there is any "reason-for-write off amount" is present for queried customers then it shows the "reason-for-write off amount" data.check boxes also created beside customer number field in Master block.If there is no "reason-for-write off amount" for any customer I need to write it and when I click on "submit" button in my form it goes to database.
Now my requirement is :
I need to make "reason-for-write off amount" field as read-only and I need to CHECK corresponding Customer "check_box" and make "SUBMIT" button as disable using personalization.
I wrote code in Personalization as
Trigger-Event:WHEN-NEW-FORM-INSTANCE
Condition: :DUMCUST.REASON_FOR_WRITEOFF IS NOT NULL
Processing mode:BOTH
Actions:
object type: ITEM
Target Object: :DUMCUST.REASON_FOR_WRITEOFF
Property Name: Enterable
Value:false
object type: ITEM
Target Object:      :XXMCS_CUSTOMER_DETAILS.CUSTOMER_NUMBER_CBX
Property Name: Value
Value:1
object type: ITEM
Target Object:      :XXMCS_CUSTOMER_DETAILS.SUBMIT
Property Name: Enabled
Value:False
But it is not working..the applied changes are not affected in my form.I tried the above actions with WHEN_NEW_BLOCK_INSTANCE trigger also.I didn't write any validation triggers for these items in my FMB also.
Could anyone please help me..
Thanks in Advance.

Answer 1

in your iterator declare the inputfield with disabled = true .
p_replacement_bee = cl_htmlb_inputfield=>factory(
                            id        = p_cell_id
                            disabled  = 'true'
                            value     = comments ).
this will generate the html like below
<input type="Text"
class="urEdf2TxtEnbl urEdf2TxtRo urV" autocomplete="off" id="TAB1_1_4" ct="InputField" name="TAB1_1_4" st="r" tp="STRING"
readonly value="some value" onblur="sapUrMapi_InputField_Blur('TAB1_1_4',event)"
onkeydown="sapUrMapi_InputField_keydown('TAB1_1_4',event)"
onkeyup="sapUrMapi_InputField_KeyUp('TAB1_1_4',event)" onfocus="sapUrMapi_InputField_focus('TAB1_1_4',event)">
now you can use js getElementById as this now has a id attached (TAB1_1_4)
