Ken Weiner commented on MYFACES-583: ------------------------------------ Is this related to http://issues.apache.org/jira/browse/MYFACES-154 ? If it is the same fix, then 154 can be resolved as well. > "Error during model data update" using selectManyCheckbox > --------------------------------------------------------- > > Key: MYFACES-583 > URL: http://issues.apache.org/jira/browse/MYFACES-583 > Project: MyFaces > Type: Bug > Components: Implementation > Versions: 1.1.1 > Reporter: Peter Mahoney > Assignee: Bruno Aranda > Fix For: 1.1.1 > > I have a selectManyCheckBox backed by an Integer array property. When the > form is submitted, I get an exception thrown when updating the model: > Caused by: javax.servlet.jsp.el.ELException: Attempt to coerce a value of > type "[Ljava.lang.Object;" to type "[Ljava.lang.Integer;" > It seems that the property is trying to be set with an Object array, rather > than Integer array. > I have tracked the problem down to _SharedRendererUtils: > ... > { > //Object array > int len = submittedValue.length; > Object[] convertedValues = new Object[len]; > for (int i = 0; i < len; i++) > { > convertedValues[i] > = converter.getAsObject(facesContext, component, > submittedValue[i]); > } > return convertedValues; > } > .. > Given that we know what type the array should be, a suggested patch for the > code is: > int len = submittedValue.length; > ArrayList convertedValues = new ArrayList(len); > for (int i = 0; i < len; i++) > { > convertedValues.add(i, converter.getAsObject(facesContext, > component, submittedValue[i])); > } > > return convertedValues.toArray((Object[]) > Array.newInstance(arrayComponentType, len)); > Peter -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
