Having s:convertDateTime for param in .page.xml seems to cause s:button to loose value for that param. If I remove s:convertDateTime from param, then clicking s:button, below' maintains the value for that param. Seam 1.2.1GA | .xhtml | <s:button view="/report/application-stat.xhtml" value="Back" action="#{applicationStat.submitSearchAction}"></s:button> | | | .page.xml | <page login-required="true" action="#{applicationStat.pageAction}"> | ... | <param name="from"/> | <param name="executeSearch" value="#{applicationStat.executeSearch}"/> | <param name="printable" value="#{applicationStat.printable}"/> | <param name="applicationDateFrom" value="#{applicationStat.applicationDateFrom}" converter="#{s:convertDateTime}"/> | <param name="applicationDateTo" value="#{applicationStat.applicationDateTo}" converter="#{s:convertDateTime}"/> | <param name="applicationDateLate" value="#{applicationStat.applicationDateLate}" converter="#{s:convertDateTime}"/> | </page> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113402#...
