I want to render radio buttons on html. I have this chunk of code
<logic resent name = "qvalues" > <logic:iterate id = "qvalue" name = "qvalues" > <html:radio property="abc" idName="qvalue" value="value" /> <bean:write name = "qvalue" property = "value" /> </logic:iterate> </logic resent>
"qvalues" is a collection i get from database. I want to iterate thru the collection and display all the radio buttons. I get this error javax.servlet.jsp.JspException: Cannot find bean under name org.apache.struts.taglib.html.BEAN at org.apache.struts.taglib.html.BaseHandlerTag.lookupProperty(BaseHandlerTag.java:945) at org.apache.struts.taglib.html.RadioTag.currentValue(RadioTag.java:198) at org.apache.struts.taglib.html.RadioTag.doStartTag(RadioTag.java:166)
If i remove this line of code <html:radio property="abc" idName="qvalue" value="value" /> and replace with regular html radio it works fine.
1-Is the <html:radio> tag enclosed in a <html:form></html:form> tag pair? 2-Does the action attribute of the form tag correspond to a valid action mapping? 3-Does the form bean that is used by the action mapping have an "abc" property?
A negative answer to any of the above might cause this error.
My form bean that is used by the action mapping doesnt have an "abc" property. I am new to struts. I was going thru some tutorials and it said property is like name of the radio button.
The property i have in form bean is 'value' so i am doing <bean:write name = "qvalue" property = "value" /> but what actually does property in html:radio do??
Property of html:radio is same as the property of any other struts component... The property name should have a corresponding valid getter and setter in the form bean. In your example, It is "abc" for radio component [ February 15, 2006: Message edited by: Raghavendra nandavar ]

in the html:radio tag, value means the value to be passed if the radio button is checked. Here's an example:
This code will produce four radio buttons. When the form is submitted, the colorValue property of the form bean will be populated with one of the four colors depending on which button is selected. [ February 16, 2006: Message edited by: Merrill Higginson ]
