Stacked Canvas - FRM-40202

I having this problem with my form. I getting a FRM-40202 error when trying to run my
form which has two stacked and 1 content canvas.I have tried hiding the canvas.
hide_view('canvas150'); go_item('control_block.pwo_nbr');
AURUT is the content one.
canvas150 is the stacked canvas I don't want to see.
AWR is the stacked canvas i would like to see.
the data blocks are as followed:
reports
range1 and range 2 are associated with the canvas150.
range 3 and range 4 are associated with the AWR canvas.
The first problem I have is that the AURUT canvas has the canvas150 canvas on top of it
I tried deleted the canvas150 canvas and recreated it but it is still on top.of the content one and I also have a stacked canvas(canvas150) in my form.
I think that my form is corrupt. How can I fixed this problem without redoing the whole form? I tried created a contol_block and assigning the items to the control_block in my program unit. But I still see canvas150. I getting frm-40202 error. What I have read about this error is that a field in my canvas150 needs to be filled in before it will allowed me to continue to the next canvas(AWR). I don't even want to see canvas150 while I processing the items on AWR. I'm lost as to what i can do to fixed this problem. If I changed the field in question in canvas150 to "NOT REQUIRED" my form crashes.
I didn't have this problem with my first stacked canvas. Introducing my second stacked canvas has cause this problem.
Thanking in advanced

If I changed the field in question in canvas150 to "NOT REQUIRED" my form crashes.This should not happen. What happens when it crashes? Is there an error message when the crash occurs?

FRM-40202 and mandatory items on a multi-tab canvas

Hi all !
Short technical question for you guys : let's say that I have datablock whose fields are displayed on different tabs of a same tab canvas. Now, let's say that two fields of this datablock are defined as mandatory : one on the first tab, the other on the last.
My problem is that my form doesn't behave correctly :
Good behavior -> After creating a record on the first tab without filling the mandatory record of the last tab, if I try to create a new record => I get a FRM-40202 error, and Forms forces me to fill the mandatory field of the last tab. Nice.
Bad behavior -> After creating a record on the first tab, I try to go to the last tab by clicking the appropriate tag name in order to fill the mandadory field => I get a FRM-40202, and Forms leaves me on the first tab, unable to fill in my record properly. I thought that as long as I wasn't leaving my record, I wasn't supposed to get a FRM-40202 error...
How would you deal with this kind of error ? How can I get this kind of error while not leaving the record ?
Thanks for your ideas and your help
Regards,

Hi,
are you sure you're not navigating to another record or block? (or trying to save...) Make sure it enabling debugging messages or tracing it...
The error message in thiscase is clear...

Child block Stacked Canvas - Data population

Dear Techies,
I dont get data refreshed in my child block C1 which is present in a stacked canvas. I show or hide it based on a condition in my post-query. When C1 has to be shown, it is shown as expected but the corresponding data is not populated in C1.
I disable another block items and get FRM-40106: No navigable items in destination block in post-query. Could this be an issue? Please assist.
Regards
Sri

Hi,
All the Data blcok items cannot be hidden and at least there should be one item which is navigable. Instead of making the items invisible, I changed the background color to gray and updatable and insert property as 'No' and it works fine now..
But actually my intention was to hide all the block items based on certain conditions...:(
Thanks

Hi ayadsufyan,
As it looks Andreas assumption of internal status change was correct. So taking into account this fact I would assume you are doing some data manipulation on the row you are unable to delete.
What I would suggest to do is to put the following code in your KEY-DELREC trigger :
clear_message;
message(:system.record_status);pause;Now when you delete the record you should get the INSERT status of the record. If so it definitely means you are doing some manipulation on the record you are trying to delete. From this point on you will have to pinpoint the offending code.
Best regards.

How to show additional items in the same window using stacked canvas

How to show additional items in the same window using stacked canvas.
My content canvas has 14 items, and I have to include more.
I want to know how I can use a stacked canvas to show these additional items in the same window, so that I can scroll through horzontally , as if all the items are on one canvas.

Well, I intially navigate into my content canvas. At this stage the stacked canvas is not visible, then how should I navigate to an item on the stacked canvas to make it visible?

How to remove the black line from a stacked canvas at run time???

Hi All,
I've developed a stacked canvas within a content canvas, when I run the form the stacked canvas apeared with a black line takes it.
How to remove this line or how to disappear this line at run time??
I tried to do this by putting (no line) in tools palette to the line color tool after selecting the black line one and after selecting the stacked canvas another once, but this did not resolve the problem!
I need something else:
I put the stacked canvas at detail data block and it didn't appear since I execute query in master data block
How to appear the stacked canvas directly before executing query in master data block???

Hi,
u mean the border line? In stacked canvas property, select contour/outline and set it to none.
Make sure, the stacked canvas is behind the content canvas in the objectnavigator. Then check your
properties of the stacked canvas:
- Position on content canvas
- size
- size of clipping
Set stacked canvas property automatic visible to yes.
Make sure the stacked canvas is not overlayed by other stacked canvas or items.

FRM-40202:field must be entered

In R12, under Service Contracts; when navigating between the two blocks 'FRM-40202' error is thrown indicating 'Field must be enetered'.
Duplication Instructions:
1) Create a new service contract with 2 usage lines and add 1 counter at subline level for each usage line.
2) Now place the cursor in the 1st usage line, navigate to Lines (tab) --> Pricing/Products (tab) --> below it shows the related subline information (counter instance).
Lines and Subline has parent-child relationship.
Lines is a parent block and Subline is a child block.
3) At subline level, we have three tabs (Effectivity, Pricing, Counters), but the data belongs to a single data block.
4) When the cursor focus is in Counters tab for the first usage line, then change the cursor focus to the next usage line at Line level; this navigation will clear the subline level details and it throws the error 'FRM-40202:field must be entered'.
5) Error is not shown when the cursor focus is in 'Effectivity' tab of subline and changing the cursor focus to next usage line at line level is successfull.
6) Counters tab has 1 field which is marked as 'Required' and when the error is thrown, it clears the current block and cursor focus remains in this field.
The same navigation in 11.5.10 instance doesn't cause any issues and there is no major code change from 11.5.10 to R12 for this navigation.
Please suggest on how to overcome the above situation.
Thanks

Well, I found the issue. I created a text field to display the passed parameter value (for debugging purposes) and by default it was defined as a database field. The error was due to the "txt_misc" field being part of the query but not existing in the database. I have since figured out how to get my parameter passing and data querying example to work.
New question:
Is there a way to debug more than one form at a time (step from one form into another called form)?
Last but not least, are there any Oracle Forms books that resemble the "Learn Visual Basic in 21 days" type format? I'd like a reference where I can look up sample syntax for a variety of tasks like ...
- calling a form
- passing parameters
- querying data
- SDI and MDI forms and their differences

Stacked Canvas issue

1st issue:-
I have created 3 pages layout under same .fmb
Out of those , page1 I have made in content canvas & 2 layout(Say page2 & page3) I have made in two different stack canvas.Page1 contain two text field- 1.NAME 2. PROFILE CODE.
when user open it page1 (content canvas) & page2 (1st stack canvas) should show .For a specific value in PROFILE CODE (say JAPAN) profile code (page1+page3) should open.& for all other profile codes (page 1+page2) should remain,irrespective of whatever value in NAME.
Please tell me how can I do this??
1. Please help me with a sample code & also where (in which trigger) I should write the condition.
2. What all changes are required in property palette?
3. will both the canvas will be on the same window?
2nd issue:-
I have tried
In the Object Navigator, under the Canvases node, double-click the content canvas' object icon. In the Layout Editor, choose View | Stacked Views.
and could see both the page1+page2 there from layout editor.
BUT while I run it its showing only the page1(content canvas)
Please help me out.....
Thanks in advance..

If I put it like this In WHEN-NEW-FORM-INSTANCE trigger check the PROFILE CODE and display the stacked canvas based on the value in PROFILE CODE---
Then content canvas will be shown first(Page1) ,then user will select profile code, depending upon the profile code selected ,either page2 (stacked canvas) or page3(stacked canvas) will be shown.
But I want whenever user opening the form ,page1 & page2 should show by default.then user will select profile code.if profile code is for page2 ,it should stay in that (default) page only.If profile code is for page3 then it will automatically go to page3 along with page1.

Stacked canvas

Hi
I have a screen where part of the block is in a 'fixed' content canvas and part is in a stacked canvas which is scrollable. Initially, both canvases are displayed and I can scroll backwards and forwards in the stacked canvas. However, when I select one of the fields that is outside the stacked canvas the stacked canvas disappears. Is there anyway of pinning the stacked canvas so that it is visible all the time.
Thanks

Hi
What i understand when your naviagation is on contact canvas item then stack canvas disappear.
it is so simple just click on the border of stack canvas and drag the stack canvas away from the items of contant canvas. it may possible your stack canvas is over the any item of contant canvas

Stacked Canvas Problem in oracle 6i form builder

Hello,
i have 2 content canvas "DTL and PUNCH",1 tab,1 horizontal canvas in window1 and 1 another content canvas "parameter" in window2.
i have created a stacked canvas under dtl canvas because
I have a master-details form. my details has more columns so im planing to use stack canvas.
but at run time it is not displaying?
please help me regarding that?
Thanks
With Regards
Vishal Agrawal

hello,
then you should set viewport x and y position of stack canvas below the height of button in DTL block.
means If button y position = 170 then
viewport position of x = 5,
viewport position of Y = (y position of button + height of button+5) . (for Stack canvas)
Same way,
If stack canvas height = 270 then
viewport position of x = 5,
viewport position of Y = (viewport position of Y of stack canvas + height of stack canvas+5) . (for Tab canvas)

Stacked canvas behaviour 6i c/s

hi,
My form has two canvases.
1. content in own window
2. stacked content in own window( which is only 5 cm by 5cm wide and does not cover content when called.
COntent canvas and window are maximised in when-new-form-ins trig.
The problem i am getting is when I call stacked can in its own window from content can via button my content canv
resizes itself enough so that scroll bars appear.
So that when i exit stacked can i have to maximise the content to such a state as when I first run the form.( all coded in when-new-form-ins) i.e dbl click on win title bar.
Does anyone know if this is default functionality or is there something I need to set ?
thanks.

hi tony
sorry for not making it very clear...
So you want to Press a button, go to a stacked canvas, pause and accept input on that canvas, then proceed to do some calculations, and all of this on >one button?what you understood up to the bold marked area is correct. after getting the input in stacked canvas the user press a back button there to hide and come out. The calculations are on the content canvas button itself...( which is used to display the stacked canvas)

Stacked canvas view placed on the content canvas

Hi to all,
i am developed a one form ,i.e placed the stacked canvas view on the content convas.
i create a two data block's with same table.
one data block for content canvas and one for stacked canvas.
in the content canvas i taken two fileds with scroll bar and remaining fields placed on the stacked canvas.
these stacked canvas view put on the content canvas.it dispalying and
executed succesfully.
here i am getting one problem i am displying the 10 records at a time in both canvases.my requirment is placed on the
cursor on the content canvas particular record scroll down then automatically show the same record details in stacked canvas and
content canvas scroll bar is changed automatically stacked canvas scroll bar is changed.
any one help me.........

{quotei create a two data block's with same table.
one data block for content canvas and one for stacked canvas.{quote}
This is not necessary. Just create one data block and then assign the block items to your Content and Stacked canvases. You can display items in a data block on different canvases. By doing this, there is no need to write code to synchronize the records because they are part of the same data block so they will automatically scroll as you navigate through your records.
