Mini-lang equivalent to while loop

[Scott Gray]

Hi All

I can't seem to find anything among the minilang tags that is equivalent
to a while loop in java, can anybody point me in the right direction or
let me know if there isn't anything?

Thanks
Scott

Hi Scott,

have a look at the receiveInventoryProduct minilang method in:

applications\product\script\org\ofbiz\shipment\receipt\ShipmentReceiptServices.xml

you'll find an example of the <loop> operation

Hmmm sorry,

however this is an equivalent for the "for" java command... I don't know
if it will help you to do what you need.

Jacopo,

I was testing the reception of a large(ish) purchase order and could
consistently get receiveInventoryProduct to raise an exception, although
with no useful diagnostics about what might be causing the problem.

Whenever I try to receive a shipment with several hundred items this
would occur. However, if I received the order in "chunks" of 20-30 items
everything worked fine. This points to a dynamic runtime error rather
than a program logic error, but the logs don't really give an idea of
what might be causing it.

Are there known problems with receiveInventoryProduct for big orders? I
couldn't see anything on jira...

Cheers, Iain

Iain,

How long is it taking to run? Perhaps you're running into the default  
transaction timeout of 60 seconds.

There are a couple of ways around this. In general even with a few  
hundred items it should go faster than 60 seconds, so some  
optimization (ie caching, db table indexing, improving queries to  
reduce database round-trips, etc) might be needed. The other  
alternative would be to increase the transaction timeout (either the  
default one, or the timeout for that specific service).

Hi Jacopo

I need to be able to break out of the loop when a condition becomes true
and it looks like i can't do this with the loop tag.  Would if be
worthwhile if I spent some time creating a <while-compare> tag (i.e. is
it likely to get committed) or otherwise I can just switch to java or
bsh to do what I need.

Thanks
Scott

Hi Scott,

From my PoV this seems interesting. I could review your patch if you create a Jira issue.
