<s:form action="saveOrUpdateProduct" method="post" enctype="multipart/form-data" validate="true" theme="css_xhtml ">
<s:textfield name="product.productName" label="Name" required="true" requiredposition="left" labelposition="left"></s:textfield>
<br>
<s:textfield name="product.productPrice" label="Price" required="true" requiredposition="left" value="1.0" labelposition="left"></s:textfield>
<br>
<s:hidden name="product.available" value="true"></s:hidden>
<s:textarea name="product.productDescription" label="Description" required="true" requiredposition="left" labelposition="left"></s:textarea>
<br>
<s:action name="populate" executeResult="true"/>
<s:file name="userImage" label="Picture" required="true" requiredposition="left" labelposition="left"/>
<br>
<s:submit value="Add"></s:submit>
<br>
</div>
</s:form>
If the file uploaded isn't a picture i would like to return to the same page with an error message, but when i try this, it shows the same page without executing <s:action name="populate">
that populates 2 <s:select>
I couldn't find an example that works. The example from Struts 2 documentation works for result name="success"
, but not for "input"
.
Why don't you make your action implement Preparable. In the prepare
method, populate the selects, rather than having an <s:action>
