POFile attachments broken upgrading to grails 1.1.1 from grails 1.1-beta3
text
Body
copied!<p>This is a rather specific upgrade path, but it's what I'm on. I think I tried going to 1.1 as well, and had the same problem, but not 100% sure.</p> <p>Anyway, I'm on 1.1-beta3 and have implemented a file upload/attachment system as outlined herer: <code>thegioraproject.com/2008/03/26/image-attachments-in-grails-using-imagemagick/</code></p> <p>I've got a 'broker' object which has a 'logo' (defined as an Image domain). The Image and Attachment (parent class) are done as defined in the above URL.</p> <p>In the brokerController, I've got code like this:</p> <pre><code> def file = new Image() def f = params.logo if(f.size>0) { file.setFile(f) file?.save(flush:true) brokerUserInstance.logo?.delete() brokerUserInstance.logo = file } </code></pre> <p>The 'logo' is the name of the uploaded file from the form. After this code there's more standard grails CRUD code (<code>brokerUserInstance.properties=params</code>, <code>brokerUserInstance.save()</code>, etc). </p> <p>This works fine in 1.1-beta3. I can upload an image, it'll get thumbnailed and attached to the domain just fine (relations are in place in the db, etc). When I update the broker object without uploading a new image, the old one it kept intact.</p> <p>Moving to grails 1.1.1, when I try to upload a new image, I get:</p> <pre><code>Error 500: org.springframework.dao.InvalidDataAccessApiUsageException: object references an unsaved transient instance - save the transient instance before flushing: Image; nested exception is org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: Image </code></pre> <p>and if I don't upload an image, I get:</p> <pre><code>[org.springframework.web.multipart.commons.CommonsMultipartFile] to required type [Image] for property logo; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [org.springframework.web.multipart.commons.CommonsMultipartFile] to required type [Image] for property logo: no matching editors or conversion strategy found </code></pre> <p>I'm able to find pretty much 0 on this issue. Works fine in 1.1-beta3, but something's changed (dramatically) in 1.1.1 (and probably 1.1 as well).</p> <p>Any suggestions/ideas/help? I'm happy to grant server access to someone to help debug this.</p> <p>Thanks :)</p>
