I have a workflow loop like this.


I want to consrtuct an HTML table during the loop that I am using in task 3
in task 1 I have a var @@tbl = '' ;
@@tbl is declared as dynaform variable
in task 2 the command @@tbl .= "<td> ....</td>" adds a table row in each loop

At the end of loop the table has the rows that I am expecting looking in the debuged window immediately after the loop.
Also, I examined Application.App_Data for current case , stoping workflow at last step of loop whith die() . The @@tbl is OK.
But, routing to task 3 after the loop, in the dynaform of task 3 the @@tbl seems to hold only the first row of table ( from the first step of loop).
The PMFSendVariables() in script code doesn't have any result.

if script task substituted by user task running the same script, the table is completed as expected ( ... of course after some "next steps" movings)
there is any idea to correct thiw problem?
thanks in advanced

I've no idea why this is happening, but it could be that the variable is getting overwritten when it is passed to Task 3.

Try saving the contents of @@tbl in another variable, like this and see if its value is preserved:
@@tbl2 = @@tbl;
(Don't define @@tbl2 as a variable in the PM interface, to eliminate the possibility that the variable is being overwritten from a previous value stored in $_SESSION or $_POST. Just define it in the trigger code.)

Are you passing the @@tbl variable from the master process to the subprocess and then back to the master process? It also could be that the subprocess is altering the variable.

Amosbatto, thank you for our response,
Subprocess is asychronous and have no return value.

Another possibility is that @@tbl is not getting saved to the database. After you change @@tbl in the trigger, add this code to save it to the database:

Code: Select all

PMFSendVariables(@@APPLICATION, array('tbl'=>@@tbl));
