Adding enctype="multipart/form-data" to form tag causes problem with update

[ashikwindu]

Hi,

I'm adding support for file upload. I've added enctype="multipart/form-data" to a form tag and it's breaking update CRUD operation.


I've changed update.tagx from

<form:form action="${fn:escapeXml(form_url)}" method="PUT" modelAttribute="${modelAttribute}">

to

<form:form action="${fn:escapeXml(form_url)}" method="PUT" modelAttribute="${modelAttribute}" enctype="multipart/form-data" >

Now, When I'm trying to edit entitity with Roo generated form, it's causing hibernate unhandled exception, unable to persist detached object.

After debugging, I've discovered that instead of update method

    @RequestMapping(method = RequestMethod.PUT)
    public String TipLokacijeController.update(@Valid TipLokacije tipLokacije, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {
        if (bindingResult.hasErrors()) {
            uiModel.addAttribute("tipLokacije", tipLokacije);
            return "tiplokacijes/update";
        }
        uiModel.asMap().clear();
        tipLokacije.merge();
        return "redirect:/tiplokacijes/" + encodeUrlPathSegment(tipLokacije.getId().toString(), httpServletRequest);
    }

create method is being called,

    @RequestMapping(method = RequestMethod.POST)
    public String TipLokacijeController.create(@Valid TipLokacije tipLokacije, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {
        if (bindingResult.hasErrors()) {
            uiModel.addAttribute("tipLokacije", tipLokacije);
            return "tiplokacijes/create";
        }
        uiModel.asMap().clear();
        tipLokacije.persist();
        return "redirect:/tiplokacijes/" + encodeUrlPathSegment(tipLokacije.getId().toString(), httpServletRequest);
    }

How can I add support for file upload without breaking "update" CRUD operation

Thank you for your answers

thank you for the answer

 I am not allowing updates in this version of the application. So, I disabled it, by setting the update=false in the @RooWebScaffold annotation.

I will do the same, although it's a workaround, for now, until I figure it out, it will do fine
