s:selectItems doesn't reload when backing collection content changes -------------------------------------------------------------------- Key: JBSEAM-4382 URL: https://jira.jboss.org/jira/browse/JBSEAM-4382 Project: Seam Issue Type: Bug Components: JSF Controls Affects Versions: 2.1.2.GA Environment: Seam 2.1.2.GA / jdk1.6.0_14/ windows xp / jboss-5.1.0.GA Reporter: Christof Van Hove links to the problem in the forum: http://seamframework.org/Community/SselectItemsDoesntReloadWhenObjectIsAd... http://seamframework.org/Community/SselectItemsValueAttributeNotUpdated The selectItems only get updated if the reference to the backing collection changes: explanation from Gena: ------------------------------------ it's a bug the line 159 within the Method Object org.jboss.seam.ui.component.UISelectItems.getValue(): Line 159: if (selectItems == null || originalValue == null || !originalValue.equals(super.getValue())) and as you can see, originalValue.equals(super.getValue()) is always true as of implementation of AbstractList Line 479: AbstractList.equals if (o == this) return true So if our base collection still be the same, selectItems doesn't refresh. And this occurs, if the selectItems was already initialized within the same request but with another count of elements (ie. for validate/convert the applied request values) there is no chance to refresh the selectItems unless recreating the collecion - so it's a bug. The new collection resolves the problem, because is not equals to cached one as of AbstractList contract. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
