Can't assign Object Text to Object Text?

Well I know this is going to be something silly, but:

Why can't I directly assign Object Text from one object to another, like this:

Object Lorem=object(1)
Object Ipsum=object(2)
Ipsum."Object Text"=Lorem."Object Text" //incorrect arguments for (=)

But this works:

Object Lorem=object(1)
Object Ipsum=object(2)
string LoremObjTxt=Lorem."Object Text"
Ipsum."Object Text"=LoremObjTxt

Maybe some kind of casting etc. is required to make the first form work?

To answer my own question, yes ... cast:

Ipsum."Object Text"=Lorem."Object Text" ""

I was sure I had tried that! :(

Ipsum."Object Text"=Lorem."Object Text" ""

The perms list will give you the reason why one is not working and the other one is. If you wish to dive into that, just say so ;-) Anyway you should check if you want to have richText (i.e. formatted text parts) copied over to the other object. In this case, you can do:
 

Ipsum."Object Text" = richText richTextWithOle Lorem."Object Text"

Thanks Mathias and Louie.
I don't know if I want to dive in any further into those perms you mentioned. But I have to do something!

My real script is STILL giving problems: I have added the "" to cast the source object to string.
But the result is I have simply substituted my original errors (-E- DXL: <Line:1243> incorrect arguments for (.); -E- DXL: <Line:1244> incorrect arguments for (=))
for new ones (-E- DXL: <Line:1243> incorrect arguments for (.); -E- DXL: <Line:1243> incorrectly concatenated tokens).

What is the source of the incorrectly concatenated token errors?

I also have one other unexplained error in my for() loop.

All of the errors (shown at the bottom) are in the following section of code:

for lookupTableCellObject in row(newLookupTableRow) do   // What is wrong with this line?? Here is the error: -E- DXL: <Line:1226> incorrect arguments for (do)

    if (colCount>=colCntLookup)
    {    
        errMsg="Unexpected cell count (too many) in newly added internal lookup table: expected count was " colCntLookup ""
        dataLogger(logERR,errMsg)
        break //skip (rest of) this invalid row

strathglass - Sun Apr 17 09:45:48 EDT 2011

Thanks for the input Louie. I will check to see if AutoDeclare is on or not.
However I always declare every variable I use.
(Couldn't find any AutoDeclare.dxl or AutoDeclareSet.dxl script here or with google, but from another thread it sounds like you can disable auto-declare by adding line "XFLAGS_ &=~AutoDeclare_" to file<C:\Program Files\Telelogic\DOORS_?.?\lib\dxl\startup.dxl>)

In this case, the sample code I provided is from a function, and at the top of the function I do indeed declare the variable lookupTableCellObject:

Object lookupTableCellObject

The next line after the declaration where this variable is used is the start of the for loop in the sample code I provided.
So I am not sure what the error could be.

As for the row() comment, I will explain how that works:

//get a data cell within table:
Object appendFromObject //not shown here, but this is initially set to be an object within a row of a table; i.e. a regular data cell in a table (not the invisible row object)
 
//now add a new row to my table, located after the row containing the above data cell:
Object newLookupTableRow=appendRow(appendFromObject) //from my testing, appendRow() returns the last data cell added in the newly created/appended row (not the invisible row object)
 
//finally, get invisible row object for the newly added row:
newLookupTableRow=getRow(newLookupTableRow) //this returns the invisible row object for the row containing the specified data cell

After this, my for() loop from my prior post starts.
So it all looks OK to me, since according to the DXL manual, the "for cell in row" loop takes the invisible row header object, and the DXL manual example actually uses the form "row(rowHeaderObject)":

//from the DXL manual (with comments added):
Object rowHead
for rowHead in table current Object do 
{
    Object cell
    for cell in row rowHead do //rowHead is already an invisible table row header object, and they are calling row() on it, so it must be OK to do this
    {
        print identifier cell "\n"
    }
}

In fact, I think I had this whole block working when I extracted out this function from the rest of the code. I think I need to try that again to confirm, which tells me it would be something somewhere else causing this. Strange.

I appreciate the input Louie. If anything above looks odd, please let me know. Otherwise I will do a bunch of testing to isolate the issue, and promise to report back what I find. :)

strathglass

Object lookupTableCellObject

//get a data cell within table:
Object appendFromObject //not shown here, but this is initially set to be an object within a row of a table; i.e. a regular data cell in a table (not the invisible row object)
 
//now add a new row to my table, located after the row containing the above data cell:

    for cell in row rowHead do //rowHead is already an invisible table row header object, and they are calling row() on it, so it must be OK to do this
    {
        print identifier cell "\n"
    }
}

At home, got no DOORS here.

I strongly suggest you put that in your startup.dxl so you can develop DXL with autodeclare off. But you still need a mechanism for turning it on (without re-starting DOORS after suppressing that line), so you can run Layouts and Attr-DXL deployed by folks taking full advantage of the autodeclare <<Disallowed Content Detected>>. Maybe I'll post that script again when I get back to work.

It won't be the first time I was wrong after being adamant I was right, but I have no idea how the following can fail complaining about parameters for "." unless lookupTableCellObject is not a variable of type Object (or some other data types).

lookupTableCellObject."Object Text"=lookupTableStaticcolCount ""

Since your original loop also failed ... in fact all the lines using that variable failed ... I'm sure I'm right about this. Perhaps you should post the script, or at a minimum the entire function along with whatever global variables it uses.

If variable "oRow" is the invisible row object, then I wonder what "row(oRow)" returns. You should verify it returns the same object but I'm suspecting it returns null.f

Your sample loop in this post looks good, but it would look a lot better if you also printed "\t" number(cell)", then you can see the hierarchy pretty well. And because I'm ADHD I would do this so I could see my nice clean orderly table:

void  PrintObj(Object obj, string Label)
{  print Label "\t" identifier(obj) "\t" number(obj) "\n"
}
Object rowHead
Object oTable = table(current Object)
if (null oTable) halt
PrintObj(oTable, "Table")
for rowHead in oTable do 
{   PrintObj(RowHead, " Row")
    Object cell
    for cell in rowHead do 
    {
        PrintObj(cell, "  Cell")
    }
}
