Generate flowitems according to time schedules on globaltable

Hi, all~

I just wonder how to generate flowitems abid by my own schedules written on globaltable.

I have a globaltable "result" to store flowitem generating schedules row by row(exact time in its row 8), and another globaltable "parameters" store the number of the next row for "result" table in its row 1 column 1.

Here are code of InterArriveTime trigger in the source1.

treenode current = ownerobject(c);
treenode parameters = reftable("parameters");
treenode result = reftable("result");
double orderrank = gettablenum(parameters,1,1);
if(gettablenum(result,orderrank,8) <= time())
value = 0;
else
value = time()-gettablenum(result,orderrank,8);
return value;

With source1's onCreation trigger, I increase the number of row1 column1 in globaltable "parameters", updating it to the row storing time for next flowitem.

However, Those codes seem to have their own idea of when to generate a new flowitem, they always set time ealier than I really need

Sophia,

Without seeing the model it's hard to debug. I would suggest that you keep the order rank in a label on the source rather than in a global table. This way you will be less likely to have someone else writting over it. Also, you didn't say whether you were resetting the order rank value on reset and I don't see where you are incrementing that value in your code.

If you can't share the model and the above doesn't help, let us know what numbers are being produced.

Good Luck,
Brandon
