Adding detail row in a table using DE

So I'm trying to implement dynamic reports. (using Birt 2.6.2) I have a saved report on disk which contains a table containing X number of row details, and I'm trying to edit the table to add more row details. 
 
I've found a thread with an example: <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/index.php/topic/16624-how-to-add-a-detail-row-to-tablehandle/#post53870'>http://www.birt-exchange.org/org/forum/index.php/topic/16624-how-to-add-a-detail-row-to-tablehandle/#post53870</a> 
<blockquote class='ipsBlockquote' >rowParm = new RowOperationParameters(2, -1, 1); 
table.insertRow(rowParm); </blockquote>
 
but when I try it, I get different exceptions depending on the RowOptionParameters parameters. 
 
My table has 1 (empty) detail row. 
 
I do: table.insertRow(new RowOperationParameters(1, -1, 0));: 
 
org.eclipse.birt.report.model.api.command.ContentException: The Row is not allowed in the slot (Groups) of Table("myTable").

The slotId param seems to be fine because if I replace it with a 0 or 2, I get Array out of bounds exceptions:

I've seen another topic with the same error, but this isn't at runtime at all... Any idea of what could be wrong? I can add columns to the table, but I can't seem to be able to add row details... 
 
Thanks!

Does (2,-1,1) not work for you if you have just one detail row? When you add a detail row, you need to do (2,-1,destination) where destination is the 0 based row number. So, if you have a row already, you add one with 1 as destination because 0 is already filled. If you have 2 already, you use 2, etc. The second number is the group, so if you're not adding a row to the group, you use -1 for no value. I think that's how it works.

Ah! Yes it works actually

(Btw, the Array out of bounds exceptions I mentioned above with slotId = 2 happened later in my code so wasn't a Birt issue... :\) 
 
A small loop experiment: 
Trying RowOperationParameters(0, -1, 0) 
Worked! Table detail count = 1 
Trying RowOperationParameters(0, -1, 1) 
Worked! Table detail count = 1 
Trying RowOperationParameters(0, -1, 2) 
Worked! Table detail count = 1 
Trying RowOperationParameters(1, -1, 0) 
Exception = The Row is not allowed in the slot (Groups) of Table("mytable"). 
Trying RowOperationParameters(1, -1, 1) 
Exception = The insert operation on the element "mytable" is forbidden. 
Trying RowOperationParameters(1, -1, 2) 
Exception = The insert operation on the element "mytable" is forbidden. 
Trying RowOperationParameters(2, -1, 0) 
Worked! Table detail count = 2 
Trying RowOperationParameters(2, -1, 1) 
Worked! Table detail count = 3 
Trying RowOperationParameters(2, -1, 2) 
Worked! Table detail count = 4 
 
 
So it's effectively like you said. I was under the impression that the slotId also needed to be incremented but yeah, slotId = 0 doesn't seem to insert anything in detail, 1 throws exceptions and 2 works

Ah, just stumbled on the src of RowOperationParameters, this info could have been in the API... 
 
/** 
* slot id. When group id is smaller than zero , slot id stands for 
* group header, or SLOT_GROUP_FOOTER; else slot id stands for 
* SLOT_TABLE_HEADER , SLOT_TABLE_DETAIL , SLOT_TABLE_FOOTER 
* 
*/ 
private int slotId; 
 
So the 2 is from a constant, not sure where it is located though... TableHandle(IListingElementModel) has DETAIL_SLOT (value 2), HEADER_SLOT (value 0), etc. but those probably aren't the same... Hmm... I should probably download the entire source... 
 
Thanks for your help!

Hello, I also having the same problem, but I'm trying to add new rows to existing GRID which already have n rows. It gave me same error stated in first post.

Sandy Wishpond

is it possible to add only n records by calling an api to a table and then use a button (next n) to fetch next n records and then repopulate the table ? Also will grouping/sorting apply be applicable then ?
