How to let the flowitem not disappear when click onreset button

hi,
I have built a model,but i don't want to let the flowitem to disappear when i reset the model. what can i do to slove this problem?

As far as I know, there is no way to have Flowitems in a reseted model.

Am not sure, if it is the easiest way, but I would use an Object and give it the look of the Flowitem. On Start I would turn the shape of this Object off and on Reset on again.
Or if you want to move exactly this Object you could use Kinematics!?
Only ideas..

I've just done some tests and it seems there are 2 things to take into account :
- The built-in FixedResource and TaskExecuter objects (Queue, conveyor, operator, etc...) seem to destroy their entire contents on reset
- Any object with the itemtype attribute is destroyed on reset

Therefore if you rename/delete the flowitem's itemtype attribute (then rebind the object's attributes), it won't be destroyed by the automatic flowitem destruction process.
You can test this behaviour as follows :
- create a source that outputs to a queue
- run the model until you have atleast 2 flowitems in the queue then stop it
- use Edit Selected Objects to move both flowitems from the queue to the model root object
- for one of the flowitems, rename the itemtype attribute to "itemtype_", then select Build->Rebind Object Attributes in the object's context menu, leave the other flowitem as it is
- reset the model, the unmodified flowitem will be destroyed, the modified one will remain

Sadly I'm not sure how you could avoid the other issue of objects destroying their contents automatically (drop any object into a queue/operator/conveyor/etc and hit reset to see this in action).
Still, this might be of use to you if your model uses custom FR/TE objects (BasicTE and BasicFR do not seem to destroy their contents automatically).

Good luck.

Hi Allister,
Thanks for your help.
I've paid attentions to the flowitem's atrribute ,but i think the atrribute is very important to the built-in FixedResource objcet. because with the atrribute the object can be managed as a flowitem by the ownobject. this is aslo the reason i put FixedResource objcet into other object. Do you know the the automatic flowitem destruction process? I just want to let this process miss the task destroying the object i want to keep. I don't know where i should check.

I've tried disabling the itemtype attribute from the model reset trigger and a dummy-object's reset trigger (so as to disable flowitem destruction just before it occurs), but sadly it seems like the flowitems are destroyed before any reset triggers are executed.

Although you could make your own reset function, which would disable the itemtype attribute on whatever flowitems you want to keep and rebind the attributes, before calling resetmodel(). I imagine that would work, although without knowing exactly what you're attempting to do, I can't garantuee it's what you want.
