Hi All,

I have a situation where I need 2 pages in a folder that are identical (almost) but serve different purposes. What I don't want to do is write two different dialog blocks to handle them.

Normally I would probably have them in one page with a toggle but that isn't clear enough on this application so I definitely need two pages in the folder.

My question - is there an easy was to move the dom contents of a page to another page (and back) according to which page has been clicked? Effectively changing the parent id of the a dom container object in the page 1 to page 2.

I would expect I would need another container object to keep each page valid, eg:

FOLDER myfolder

  PAGE page1
    VBOX page1_root
       VBOX page_contents
           -- all the stuff I want
       END -- VBOX page_contents
    END -- VBOX page1_root
  END -- PAGE page1

  PAGE page2
    VBOX page2_root

    END -- VBOX page2_root
  END -- PAGE page2

END -- FOLDER

So attach the node page_contents (or all the children of page1_root) to page2_root.

I would appreciate any help on this as it is a very large dialog block I would need to duplicate just to make it look better.

Don't worry, it was simple enough to write a function to do it.

Incase anyone ever needs to:

# Will swap the SINGLE child of page 1 and the single child of page 2 with each other
#
FUNCTION swap_page_contents(f_page_from, f_page_to)
 
    DEFINE f_page_from, f_page_to           STRING
 
    DEFINE fw_window                        ui.Window       -- Your window
 
    DEFINE fd_page_from, fd_page_to         om.DomNode      -- The pages
    DEFINE fd_cont_from, fd_cont_to         om.DomNode      -- The content
 
    LET fw_window       = ui.Window.getCurrent()
 
    LET fd_page_from    = fw_window.findNode("Page", f_page_from)
    IF ( fd_page_from IS NULL )
    THEN
        ERROR SFMT("Page '%1' could not be got", f_page_from CLIPPED)
        RETURN FALSE
    END IF
    IF ( fd_page_from.getChildCount() != 1 )        -- For simplicity we want to move one big block, not several
    THEN
        ERROR SFMT("Page '%1' has too many children to move", f_page_from CLIPPED)
        RETURN FALSE
    END IF
 
    LET fd_page_to      = fw_window.findNode("Page", f_page_to  )
    IF ( fd_page_to   IS NULL )
    THEN
        ERROR SFMT("Page '%1' could not be got", f_page_to   CLIPPED)
        RETURN FALSE
    END IF
    IF ( fd_page_to.getChildCount() != 1 )        -- For simplicity we want to move one big block, not several
    THEN
        ERROR SFMT("Page '%1' has too many children to move", f_page_to CLIPPED)
        RETURN FALSE
    END IF
 
    LET fd_cont_from    =   fd_page_from.getFirstChild()
    LET fd_cont_to      =   fd_page_to.getFirstChild()
 
    CALL fd_page_from.removeChild(fd_cont_from)     -- Will orphan fd_cont_from
    CALL fd_page_to.removeChild(fd_cont_to)         -- Will orphan fd_cont_to
 
    CALL fd_page_to.appendChild(fd_cont_from)       -- Now attaches fd_cont_from to page fd_page_to
    CALL fd_page_from.appendChild(fd_cont_to)       -- Now attaches fd_cont_to to page fd_page_from
 
    RETURN TRUE
 
END FUNCTION

and then:

        ON ACTION fcf_1401reqsl
            IF ( m_has_content != "fcf_1401reqsl" )    -- m_has_content defaulted to fcf_1401reqsl earlier
            THEN
                IF ( swap_page_contents("fcf_1401reqmc", "fcf_1401reqsl") = TRUE )
                THEN
                    LET m_has_content = "fcf_1401reqsl"
                END IF
            END IF
 
        ON ACTION fcf_1401reqmc
            IF ( m_has_content != "fcf_1401reqmc" )
            THEN
                IF ( swap_page_contents("fcf_1401reqsl", "fcf_1401reqmc") = TRUE )
                THEN
                    LET m_has_content = "fcf_1401reqmc"
                END IF
            END IF
