SimpleTogglePanel's opened attribute only works with String bean properties --------------------------------------------------------------------------- Key: RF-7206 URL: https://jira.jboss.org/jira/browse/RF-7206 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-input Affects Versions: 3.3.1 Environment: JRE 6, Tomcat 6 Reporter: Matthew Lieder Assignee: Nick Belaevski Priority: Minor Fix For: Future Given the bean public class MyBean { public boolean getBooleanProp() { return true; } public void setBooleanProp(boolean prop) {} public boolean getStringProp() { return "true"; } public void setStringProp(String prop) {} } and the XHTML <rich:simpleTogglePanel label="Close Me" switchType="client" opened="#{myBean.booleanProp}"> Blah blah blah </rich:simpleTogglePanel> I get the following error if I close the tab panel and then submit the page: /test.xhtml @646,220 opened="#{myBean.booleanProp}": java.lang.IllegalArgumentException: argument type mismatch If I change the opened attribute to #{myBean.stringProp} however, then it works fine. The problem seems to narrow down to the following method in UISimpleTogglePanel: public void setOpened(boolean opened) { setValue(new Boolean(opened).toString()); }
