Recover fields value from an entry of the list

Hi,

today I inserted a fixed arguments in the fields of a list with the command listpush("mylist",id,0,argument1,...), but I am not able to retrieve the value when I pull the entry from the list because the listpull command returns only the value of the entry and from the value I can't recover the value of the field.

I attached a model which reproduces my problem.

Can someone help me?

pullfromlist.fsm

FlexSim 16.2.1
listpull from listretrieve fields from list
pullfromlist.fsm (18.0 KiB)

Maybe you query before the pull from list activity and evaluate the entries of the instance to assign them to label values.

I discovered that entire entry of the list can be pulled by command "listpull" with the flag LIST_PULL_ENTRY_NODES, but from the return value I am able to get only the push time value. How can I get the static field of the entry? I tried the command getstdvalue(entry,"staticFields"), but I failed. Any ideas? @Matt Long

There currently isn't a way to do this. It's on our radar for integrating this functionality using the SELECT statement, but nothing yet. The work around would be to push a token or other node to the list and store that field value on the token/node.

Hi @Matt Long,

have you done some integration about this topic? I'm using FlexSim 17.0.2, but I didn't note any difference. Do you confirm?

Moreover I'm using a C++ code and I discovered that staticFields is defined like "private" in the class Entry of the List then I can't access. Is there a different workaround with C++ code?

Alessio,

We haven't added anything related to this yet. I tried an initial implementation, but there were unforeseen issues with it, so we took it out.
