Re: [TOBAGO] problem selecting current item in tx:selectOneChoice
I've fixed it in the current trunk and the current 1.0.x branch, so it will be available in version 1.0.26. (See my mail form 23. April, 23:19 CEST) Regards Udo I'm not really understanding why the mapping does not works with tc:selectItem but for know I have a working solution.
Re: [TOBAGO] problem selecting current item in tx:selectOneChoice
Hello Udo, thanks for the comprehensive answer. I decide to use solution no. 5 and it works fine for me. But I dont't use enums because the underlying objects are also used for hibernates and it'makes some trouble to mapped them to the hibernate datatypes. I'm not really understanding why the mapping does not works with tc:selectItem but for know I have a working solution. Thanks best regards Michael Udo Schnurpfeil schrieb: Hi Michael, there are more than one solution for that, but as far as I know there is not cast operator... 1. use a managed bean faces-config.xml: managed-bean managed-bean-nameintValues/managed-bean-name managed-bean-classjava.util.ArrayList/managed-bean-class managed-bean-scopeapplication/managed-bean-scope !-- or use none -- list-entries value-classjava.lang.Integer/value-class value0/value value1/value value2/value /list-entries /managed-bean JSP/Facelet: tc:selectItem itemValue=#{intValues[1]} itemLabel=suspended/ (simple, scales not good, works with JSF 1.1, 1.2 and JSP and Facelets) 2. write a EL-function AFAIK: works with facelets and/or JSF 1.2 but may not work with JSP and JSF 1.1.

Re: [TOBAGO] problem selecting current item in tx:selectOneChoice
Hi Michael, I've thought about that problem and implemented a solution that works for the most cases. See: https://issues.apache.org/jira/browse/TOBAGO-877 With the current sources your example should work now, without any of the modifications I told you. Which version of JSF you are using? The f:selectItem works not with JSF 1.1, but the tc:selectItem works with 1.1 and 1.2.

Re: [TOBAGO] problem selecting current item in tx:selectOneChoice
Hello Volker, thanks for reply. Now my tx:selectOneChoice box looks like the following. Converter is away and values in braces tx:selectOneChoice value=#{myController.active} label=active f:selectItem itemValue=#{0} itemLabel=inactiv / f:selectItem itemValue=#{1} itemLabel=activ / /tx:selectOneChoice but now nothing works even not storing the values in the Controller. if I use the version without the braces I can store the value but the old problem is there that rendering the current id of active is not selected in the tx:selectOneChoice : tx:selectOneChoice value=#{myController.active} label=active f:selectItem itemValue=0 itemLabel=inactiv / f:selectItem itemValue=1 itemLabel=activ / /tx:selectOneChoice The getter and Setter definition looks like the these ones: private Integer active; public Integer getActive() { return active; } public void setActive(Integer active) { this.active = active; } Any idea else?
