Struts: solving “According to TLD or attribute directive in tag file, attribute value does not accept any expressions”

This error happens when you try something like:

<s:textfield value=”${someField}”/>

And it is caused because, starting from struts 2.1.x, JSP EL expressions  are not allowed in in the tag’s attributes to avoid a security issue.

Use OGNL instead.

If  you have a custom .tag file (where you’d use ${someField}), you can replace this with %{#attr.someField}.

Your s:textfield in the .tag file would then become:

<s:textfield value=”%{#attr.someField}”/>
