[CS2-JS] Error when inserting some text in table cell via XMLElement

Question

I have a very very strange InDesign behaviour when using XMLElement in a table Cell to insert a string.
For example (in a table that has an XML structure) :
var cell = table.cells[0];
var cell_xe = cell.associatedXMLElement;
var newtag_xe = cell_xe.xmlElements.add("mytag", null);
// Up to now, no problem
// Then I use only one of these following instructions at a time :
newtag_xe.contents = "existe en 4,57 x 1,07 m"; // Gives an InDesign error "Object is invalid"
newtag_xe.contents = "existe en 4,57 x 1,07 "; // Works fine
I have a lot of other examples of that kind (not only failing on the last character). InDesign accepts (randomly, it seems) some strings and rejects some others, and no logical rule seems to emerge.
Anyone with the same problem ?

Hi Cyril,
re: "This is where I think InDesign is really not fair : myTextFrame.tables.length == 0 if the table cannot be seen because of vertical overflow !!!"
I disagree. If the table does not appear in the text frame, then it shouldn't be in the text frame object. If the table appeared as a child of the text frame when it does nto appear in the frame (when it might have moved to another text frame in the story), it would be even more confusing.
This points out the danger of relying on the text frame as the container--instead, use the parent story of the text frame, which will contain all of the text in the story, regardless of whether it's visible or not.
Thanks,
Ole
