The method setValue(String) in the type OptionTag is not applicable for the arguments (Object)

Question

I have the below code in my JSP. The problem is while i run this code, i get the below exception:

The method setValue(String) in the type OptionTag is not applicable for the arguments (Object).  

Does anyone have an idea?

<html:select property="selectedServices" name="specificStoreForm" multiple="true" styleClass="services">
  <logic:iterate id="service" name="services" property="selectedServices">
  <bean:define id="textVal" name="service" property="value" toScope="request"/>
  <html:option value="<%=textVal%>">
    <bean:write name="service" property="label"/>
  </html:option>
  </logic:iterate>
</html:select>

Answer 1

Judging from the documentation the result from the <bean:define> tag is of type Object if you don't specify a value attribute. The <html:option> tag only works if the passed value is of type String.

Use EL (Expression Language) to get the value instead:

<html:option value="${textVal}">
    ...
</html>

You could also just use the <html:optionsCollection> tag and not have to explicitly iterate:

<html:select property="selectedServices" name="specificStoreForm" multiple="true" styleClass="services">
    <html:optionsCollection name="services" property="selectedServices" value="value" label="label"/>
</html:select>
