Daniel Riquelme commented on OFBIZ-4932:
----------------------------------------
Yes, you may test it by modifying the file:
applications/accounting/widget/InvoiceForms.xml line: 368
(EditInvoiceItems)
add the following use when condition to field quantity:
use-when="quantity!=null @and quantity.compareTo(java.math.BigDecimal.ONE)==0"
Go to
https://localhost:8443/accounting/control/listInvoiceItems?invoiceId=demo10001&invoiceItemSeqId=00002
You will get an "...Error evaluating BeanShell use-when condition ..."
Apply the patch
You will get expected behavior.

> The problem is that on multi forms the bshInterpreter gets pushed to higher
> levels on the context stack when iterating the form rows.
> What is intended in the code is to reset the bshInterpreter
> (this.resetBshInterpreter(context);) for each row iteration, this reset
> translates into a key object being removed from context, this context is
> stored in a stack data structure. The removal assumes the value will always
> be at level 0, yet what happens is that the value resides at a higher level.
> The fix is to perform the removal prior to context modification, this way the
> bshInterpereter object would be at level 0 upon removal.
