how to make subform's overflow trailer working

[Former Community Member]

Hi,

It's appreciate if you have suggestions on issue described below.

I have a static form design with table tblItemList.

I want to use overflow trailer on this table, accordingly I did follows:

1) wrap tblItemList into subform frmTableItemList. ( flowed, top to bottom)

2) define subform overflowTrailer, positioned, hidden

3) define frmTableItemList "object"

->Pagination-> Overflow trailer: overflowTrailer

->Subform -> "Allow page breaks within Content"

Problem:

overflowTrailer is not appear when page breaks.

Here is the form design xdp file.

Here is the sample data you can use to reproduce problem:

Here is the hierarchy screen-shot:

Issue is overflowtrailer is not checked to repeat(select the subform got properties Object -> Binding Tab -> Check Repeat for each data item).

also place the overflow trailer/leader under Referenced Objects under hirarchy, so that it will work properly.

you can see the difference with overflow trailer/leader placed in usual subform and under Referenced Objects - if not placed under referenced objects the trailer will come at the end (in ur case Table will be continued....) even u dont have any more to show.

Tons of thanks! The updated version works perfectly.

So put the  overflow trailer/leader under Referenced Objects making them turning into a "proto" element but not an ordinary "subform", correct?

Yes you're right that I have to check "repeat for each data item" both for overflow header/trailer.

However I'm still confused why it's mandatory.

As far as I understand, the "proto" elements are applied to subform frmTableItemList ( which is wrapping the table), or rather, are applied to this table's property "break".

<subform w="176mm" layout="tb" name="frmTableItemList">

....

<break overflowTrailer="#overflowTrailer1_ID" overflowLeader="#overflowLeader_ID"/>
            <?templateDesigner expand 1?>

</subform>

So if pagebreak happened to frmTableItemList, there should always be header/trailer appeared ( though in fact there isn't if not checking "repeat" option). This is what I expected.

Why I have to check the "repeat" option for overflow trailer/header?

Thanks again for help.

Just for intuitive purpose, following is the screenshot for structure of the xml.

Here break/overflow is per page so leader/trailer required to check that repeat box. Please check the "To create and assign overflow leaders and trailers" topic in designers help for more details.
