[seam-issues] [JBoss JIRA] Resolved: (JBSEAM-4413) Date format error in .page.xml params when having custom date pattern

Date format error in .page.xml params when having custom date pattern --------------------------------------------------------------------- Key: JBSEAM-4413 URL: https://jira.jboss.org/jira/browse/JBSEAM-4413 Project: Seam Issue Type: Bug Affects Versions: 2.1.2.GA Environment: Seam 2.1.2.GA, DB2 http://fisheye.jboss.org/browse/Seam/branches/community/Seam_2_1/src/main... Reporter: Julien Kronegg Assignee: Marek Novotny Priority: Minor Fix For: 2.2.1.CR1 Original Estimate: 1 day Remaining Estimate: 1 day The java.util.Date passed by <param> tags in the .page.xml file are converted from Date to String for the GET request, using the date format defined in the last used rich:calendar. Then, the GET parameters are converted back from String to Date using the default date format which may not be the same as the one defined in the rich:calendar. This results in date conversion errors such as "value must be a date, eg. 10/13/2008". The issue is fully described with an example in http://seamframework.org/Community/DateFormatErrorInPagexmlParamsASeamIssue To correct this issue, the org.jboss.seam.navigation.Param should use its own date converter instead of sharing the converter with other JSF components (in other words, the Param class should use a technical date converter). This requires the following steps: 1) define a org.jboss.seam.faces.DateParamConverter date converter with a selectable date format defaulted to "yyyyMMddHHmmssSSS" 2) change the org.jboss.seam.navigation.Param class to use a the DateParamConverter converter if the param value is java.util.Date, else, use the converters registered in JSF. This is done by changing: Class<?> type = valueExpression.getType(); if (type==null) { return null; } return FacesContext.getCurrentInstance().getApplication().createConverter(type); by Class<?> type = valueExpression.getType(); if (type==null) { return null; } + if (type.equals(Date.class)) { + return org.jboss.seam.faces.DateParamConverter.getInstance(); // return an instance of the technical converter, to be created + } else { return FacesContext.getCurrentInstance().getApplication().createConverter(type); + }
