Jacques Le Roux commented on OFBIZ-5385:
----------------------------------------
Like I believe for OFBIZ-5389, this is due to changes Adrian did recently where
he introduced some immutable variables. One of those commits is
http://svn.apache.org/viewvc?view=revision&revision=1471283
In OFBIZ-5389, you say
{quote}
Cache searches seem somewhat ubiquitous throughout the purchase orders. Does
anyone know if this was intentional for some reason which would require the
user to clear cache before the new products register for use?
{quote}
Actually this was working as is before Adrian's changes. At this stage I don't
know yet if we should revert those, improve them, or change all related
possible cases in OFBiz to not use cache. I have no ideas if the last would be
large or not, and if it should be the way because we would have to consider the
performance impact in each case.
Though I did not review much of his work, I think Adrian were right to do what
he did. Now we have to measure the impacts of it before changing things like
you suggest. Though I both cases, from what I have quickly seen, we could use
your changes because there are not much possible performance impacts (the
service and the worker method should not be used intensively). Maybe the way,
but we should try to see before the possible other cases to handle. It would be
then better to do it as a whole...

> Project: OFBiz
> Issue Type: Bug
> Affects Versions: SVN trunk
> Reporter: Christian Carlow
> Attachments: ProductWorker.java.diff

>
> This error message is generated when trying to add a variant product to a
> purchase order cart after features have been selected:
> Error calling event: org.ofbiz.webapp.event.EventHandlerException: Problems
> processing event: java.lang.IllegalStateException: This object has been
> flagged as immutable (unchangeable), probably because it came from an Entity
> Engine cache.
> To reproduce:
> 1. Add new feature "Gold" as COLOR Feature Type to Widget Features Category
> 2. Change WG-9943 virtual variant method to "Feature Tree Generation" on the
> product page
> 3. Add new "Gold" feature to WG-9943 on feature page of product app
> 4. Create new purchase order from BigSupplier for WG-9943
> 5. Select the new feature "Gold" as the color
> The error is generated after trying to add the product after all features
> have been selected.
