http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23332 RadioGroup tag to avoid using scriplet expressions with nested iterators Summary: RadioGroup tag to avoid using scriplet expressions with nested iterators Product: Struts Version: 1.1 Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Custom Tags AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I believe that there is a need for the RadioGroup tag. If the radio tag us iused inside nested iterate tags then the scriplets is the only (?) solution currently to get it working. Here is an example. The jsp operates on the collection of the Question instances. And each question has a list of pre-defined answers to choose from. The idea is to list all of the questions and then collect the answers chosen. The "list" and "text" types are working (generating both name="questions[x].answer", where x is the index of the question) but radio does not. If indexed="true" is specified, then each pre-defined radio answer has a name="questions[x].answer" WHERE x is the index of the PRE-DEFINED ANSWER from the predefinedAnswers iterator (not from the questions iterator). If indexed attribute is not specified, then the input field name is rendered just as name="answer". Here is the relevant portion of the jsp: <logic:iterate id="questions" property="questions" name="questionSetForm"> <logic:equal name="questions" property="type" value="list"> <div>It's a list</div> <html:select name="questions" property="answer" indexed="true"> <html:optionsCollection name="questions" property="predefinedAnswers" value="id" label="label"/> </html:select> </logic:equal> <logic:equal name="questions" property="type" value="text"> <div>It's a text</div> <html:text name="questions" property="answer" indexed="true" /> </logic:equal> <logic:equal name="questions" property="type" value="radio"> <div>It's a radio choice</div> <logic:iterate id="predefinedAnswer" property="predefinedAnswers" name="questions"> <html:radio name="questions" property="answer" value="id" idName="predefinedAnswer"> <bean:write name="predefinedAnswer" property="label" /> </html:radio> </logic:iterate> </logic:equal> </logic:iterate> The questionSetForm class defines only one property that hold a collection of Question instances: public List getQuestions() { return questions; } public void setQuestions(List questions) { this.questions = questions; } The Question class defines the following relevant properties (along with corresponding get/set methods): private Integer id = null; private Integer questionSetId = null; private String type = null; //Holds the collection of the PredefinedAnswer instances private List predefinedAnswers = null; private String label = null; private String answer = null; The PredefinedAnswer class defines the id and label properties used to render the list of choices. The only solution (work around, rather) that comes to mind is to add the indexId attribute to the external loop and use its value in the radio property: <logic:iterate id="questions" property="questions" name="questionSetForm" indexId="index"> ... <html:radio property="<%= \"questions[\"+ index +\"].answer\"%>" value="id" idName="predefinedAnswer"> I believe that this example demonstrates the need to the RadioGroup tag that would work similar to the existing Select tag by defining the name of the property there. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
