POsave(flush: true) is not flushing the session

    <p>I was creating a new grails app with several domain classes and controllers. All my controllers have working methods for save(), update() and list(), e.g.</p> <pre><code>def update(Long id, Long version) { def crawlerConfigInstance = CrawlerConfig.get(id) if (!crawlerConfigInstance) { flash.message = message(code: 'default.not.found.message', args: [message(code: 'crawlerConfig.label', default: 'CrawlerConfig'), id]) redirect(action: "list") return } if (version != null) { if (crawlerConfigInstance.version &gt; version) { crawlerConfigInstance.errors.rejectValue("version", "default.optimistic.locking.failure", [message(code: 'crawlerConfig.label', default: 'CrawlerConfig')] as Object[], "Another user has updated this CrawlerConfig while you were editing") render(view: "edit", model: [crawlerConfigInstance: crawlerConfigInstance]) return } } crawlerConfigInstance.properties = params if (!crawlerConfigInstance.save(flush: true)) { render(view: "edit", model: [crawlerConfigInstance: crawlerConfigInstance]) return } flash.message = message(code: 'default.updated.message', args: [message(code: 'crawlerConfig.label', default: 'CrawlerConfig'), crawlerConfigInstance.id]) redirect(action: "show", id: crawlerConfigInstance.id) } </code></pre> <p>which is actually an autogenerated / scaffolded method by IDE</p> <p>However, now I was adding an additional controller method which should run through a list of domain objects and update them accordingly. Getting the list, changing the attributes and validation is successfull.</p> <p>save(flush:true) doesn't throw any errors and returns the updated domain object, as expected. However, checking the hibernate SQL statements, all I see is SELECTS, no update. In fact, if I directly call a delete() on the domain object after the save(), I get a concurrent transaction exception on the domain object.</p> <p>My controller method looks like</p> <pre><code>def doSomething() { def results = CrawlerConfig.findAll(bQ) results.each { crawlerConfigInstance -&gt; crawlerConfigInstance.needsReview = true if (!crawlerConfigInstance.save(flush: true)) { render(view: "show", model: [crawlerConfigInstance: crawlerConfigInstance]) return } } redirect(action: "list") } </code></pre> <p>Pretty straightforward. If I check for the dirty fields, needsReview is marked as dirty before the save(). save() updates the version on the object.</p> <p>I currently still use h2:mem as database.</p> <p>For me it looks like the transaction is not finished. But I don't get why or how I can get it to finish.</p> <p>Thx in advance</p> <p><strong>EDIT after POST from Ondrej</strong></p> <p>created a Service (which gets injected and called fine)</p> <pre><code>package lizard </code></pre> <p>import org.springframework.transaction.annotation.Transactional</p> <p>@Transactional class CrawlerConfigPersistenceService {</p> <pre><code>static transactional = true def checkRequirementsForCrawlerConfigList(String query) { def results = CrawlerConfig.findAll(query) results.each { crawlerConfigInstance -&gt; crawlerConfigInstance.needsReview = true if (!crawlerConfigInstance.save(flush: true)) { println crawlerConfigInstance.errors.getAllErrors() return } } } } </code></pre> <p>But this results in exactly the same behaviour, everything looks OK, except that there is no update statement raised by hibernate</p>

    1. COthings I forgot to mention: I'm using currently grails 2.1.1, creating new Objects in Database even in Controller works, just not updating existing ones.

    2. COwhat happens when you forcibly call session.flush()? Do you see the db writes or some other error popping up?

    3. CONope nothing. When I call executeUpdate() it forcibly gets written. But never when I call save. I even tried to open a transaction on the hibernate session mysqlf, which failed badly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
