I created a flash chart in APEX of type "2D Column". When I run the page, it displays "waiting for data" with a processing sign.
Its not displaying any chart at all. The page processes (waiting for data) indefinetely. What could be the fault?
Kindly suggest.

I am a beginner in APEX, but experience in Oracle Designer and Forms.
I was wondering if it's possible to create a master detail page with multiple tabs(details)? like with Oracle Designer?
Much appreciated!

In APEX, how can we create screen mockup (prototypes). I read somewhere that we can definetly do that but couldnt get any good information. I am currently using some free tool (Axure RP) to develop the screen prototypes.
Please direct me if we can do that using APEX drag&drop feature.
Thanks,

I have one tabular form. I want to add browse button column in that form. I cannot add that field directly as tabular form is not supporting blob data. Is there any solution to add browse button column to tabular form and upload files?
I have added one NULL column for upload document. and used html expression
and written process to upload cv as:
BEGIN
FOR I IN 1..APEX_APPLICATION.G_F40.COUNT
LOOP
INSERT INTO document(doc_ID, doc_TYPE, LANGUAGE, doc_DATE, FILE_REF, MIME_TYPE, person_ID )
SELECT doc_SEQ.NEXTVAL,
1,
1,
SYSDATE,
BLOB_CONTENT,
MIME_TYPE,
APEX_APPLICATION.G_F02(I)
FROM WWV_FLOW_FILES WHERE NAME = APEX_APPLICATION.G_F40(I);
DELETE WWV_FLOW_FILES WHERE NAME = APEX_APPLICATION.G_F40(I);
END LOOP;
END;
but still it is not uploading file in the database.
can anyone help me "What is the Problem with above code?"
When we are creating file browse button then it creats
a class="eLink" tabindex="999" rel="nofollow" href="/[removed]popupURL('f?p=4000:371:3494102961234719:::
371_ID,FB_FLOW_ID,FB_FLOW_PAGE_ID:1189512577311801,101,
40');" title="Edit"> and one hidden field whose value equals to 1189512577311801 (it changes per item)
As I have created Null column for browse button it is not creating as well as not creating hidden item.
That's why I am not getting file uploaded .... So is there any solution for this problem?.....Please help me on this .....

Thanks for the knowledge pool you have put together for APEX.
I am kind of new to APEX and working my way out
.... I have a question w.r.t conditional display of values in dropdown.
There are dropdown combo lists in a region (on a single page). And these 3 dropdowns are dynamic LOVs coming from different database table.
i.e. Dropdown1 --> Table1
Dropdown2 --> Table2
Dropdown3 --> Table3
My goal is to show only first dropdown when a user comes to that page first time. And depending upon the selection made from the first dropdown, I want to show the second dropdown (only for few values in 1st dropdown this second dropdown should be shown) and subsequently based on the value selected from second dropdown, the third dropdown should show a refined list which is a subset of all the rows in table 3.
If someone else have confronted with similar kind of issue , please let me how you worked on it or direct me.
Thanks,
