Date format in Matrix loaded by DataTable is shown as 20080319

Question

Hello,
I've loaded most of our matrixes with DataTables. No problems up to now. Also date columns where shown in correct B1 GUI format.
But now with a new matrix the date is 'suddenly' shown as '20080319'. When I view at B1 system information (at the bottom of B1) the column is described correctly with B1 GUI format:
U_DateEndPr (Date)
19.03.2008 [Form....Item..., U_DatEndPr]
I've made a test (one of many):
I've loaded the 'problem-matrix' with some columns (including one date column) from another DataTable which works correctly on another Matrix/Pane.
The result is the same:
In the first (correct working) matrix (pane 1) the date is 19.03.2008 and
in the second matrix 20080319
Is there something wrong with the matrix itself?
I have absolutly no idea where my fault is.
Does anybody made the same or similar experiences?
So long,
Roland

Answer 1

Hello Petr,
for the test which I've made i can say yes: I've loaded the problem-DataTable with the same query as the working dataTable.
The only difference is:
The problem-matrix has less columns than the working matrix. So I couldn't bound the problem.-DataTable/Matrix to all of the query result columns.
Another hint:
The Date format '20080319' looks like the result of SDK-ValueEx (B1-DB-Format-String)
In another column beside '20080319' there's a double-value. This is shown with the correct decimal-separator of B1 (I've changed decimal sep. to '#' for test. The columns ar shown as:
'20080319'  |  142#89
...so the second column is displayed correctly but the date format is still wrong...
And:
I get the same result when I do the problem-DataTable bind to exactly the same dataTable-UID as of the working DataTable.
So at the moment I suppose that the error is in the Matrix-Object. Because both matrixes are loaded by the same DataTable (for trial) and only one of them shows wrong date-format.
I forgot:
The form with the problem-matrix was made with a 2 years old screenpainter. Althogh I've made changes on the form with a actual screenpainter - could this be a problem?
Hmm, but I don't think so because on another pane and matrix of the same old form the date works corectly...
