vinod commented on TRINIDAD-1890:
---------------------------------
We are using Trinidad 1.2.14, and we need to use tr:inputfile
<jsp:directive.page contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"/>
<f:view>
<tr:form usesUpload="true">
<tr:document title="InputFile Demo">
<tr:inputFile id="inputFileName" label="Label"
valueChangeListener="#{fileUploadBacker.uploadFileValueChange}"
value="#{fileUploadBacker.inputFile}" />
<tr:commandButton text="Submit" action="#{fileUploadBacker.uploadFile}"
/>
</tr:document>
</tr:form>
</f:view>
When ever we use usesUpload="true, we are getting the NullPointer exception
upon submitting. And when we remove the usesUpload attribute, the file input
doesnt contain any reference to the uploaded file.
java.lang.NullPointerException
