Re: Conversion problem String / float

[Stephane Cosmeur]

Thanks for helping

here is the strutsProduct.xml ::


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd";>

<struts>
<package name="PRODUCT" extends="custom-default">

        <action name="EditOption" method="editOption"
class="ttc.action.ProductAction">
            <result name="success" type="redirectAction">
            <param name="parse">true</param>
            <param name="actionName">InfoProduct</param>
            <param name="id">${idProduct}</param>
            </result>
            <result name="error">/pages/error/role.jsp</result>
            <result name="input">/pages/product/infoOption.jsp</result>
        </action>

        <action name="InfoOption" method="optionAction"
class="ttc.action.ProductAction">
            <result name="success">/pages/product/infoOption.jsp</result>
            <result name="error">/pages/error/role.jsp</result>
        </action>

        <action name="InfoProduct" method="findProduct"
class="ttc.action.ProductAction">
            <result name="success">/pages/product/infoProduct.jsp</result>
            <result name="error">/pages/error/role.jsp</result>
        </action>

</package>
</struts>


here is the form ::


<s:form action="EditOption" method="POST" enctype="multipart/form-data"
id="EditProductForm" theme="simple">
    <table width="550px;">
<tr><td>Title : </td><td><s:textfield name="titleOption"/></td></tr>
 <tr><td>Description : </td><td><s:textarea
name="descriptionOption""/></td></tr>
<tr><td>Price : </td><td><s:textfield name="priceOption""/></td></tr>
</table>
</s:form>


here is the action into ProductAction ::


public String editOption() {

      ProductOption opt = new ProductOption();

     opt.setTitle(this.titleOption);
      opt.setDescription(this.descriptionOption);
     opt.setPrice(this.priceOption);
      this.serviceFactory.getOptionService().save(opt);

     return execute();
    }

I get the field priceOption into editOption() in ProductAction, priceOption
is a float type.
In debug, i get this error : ognl.NoConversionPossible.
If i want this working, i have to send priceOption into a string in
editOption() and parse into a float, then i can set the attribute and save
the option.
The model Product has a float type for price.
