-------------------------------------
Summary: Executing multiple queries in batch request leads to
parameters mismatch / not found
Key: OLINGO-1262
URL: https://issues.apache.org/jira/browse/OLINGO-1262
Project: Olingo
Issue Type: Bug
Components: odata2-jpa
Affects Versions: V2 2.0.10
Reporter: Milko Todorov
Hello Olingo community,
we have an issue when sending multiple queries packed in batch request. Often
upon restart of our application (when the caches are empty), the first
execution of a particular batch request which contains quite a number of
queries we are getting one of the following errors (most of the time the first
one):
{color:#d04437}!/jira/images/icons/emoticons/error.png|width=16,height=16,align=absmiddle!
You have attempted to set a value of type class java.lang.String for
parameter 5 with expected type of int from query string {color}
{color:#d04437}SELECT E1 FROM CreditProduct E1 WHERE
(((E1.creditProductPk.creditAgencyId = ?2) AND ((E1.creditProductTypeCode = ?5)
OR (E1.creditProductTypeCode = ?8))) AND (E1.isDeactivated = false)).{color}
{color:#d04437}!/jira/images/icons/emoticons/error.png|width=16,height=16,align=absmiddle!
Query argument 33 not found in the list of parameters provided during query
execution.{color}
{color:#d04437}!/jira/images/icons/emoticons/error.png|width=16,height=16,align=absmiddle!
While trying to invoke the method
java.lang.String.contains(java.lang.CharSequence) of a null object returned
from
org.apache.olingo.odata2.jpa.processor.core.ODataParameterizedWhereExpressionUtil.getJPQLStatement(){color}
{color:#d04437}!/jira/images/icons/emoticons/error.png|width=16,height=16,align=absmiddle!
Query argument 3 not found in the list of parameters provided during query
execution.{color}
{color:#333333}It looks like that the issue could be in class
{color}*ODataParameterizedWhereExpressionUtil* where the
*parameterizedQueryMap* is defined. It is defined as static and it looks like a
concurrency issue. Is there a reason behind defining this map as static?
As soon as the queries runs one time and the caches are filled we don't have it
anymore unless the app is restarted.
Could you please assist us with finding a solution here?
Thank you,
Milko
