  • org.hibernate.TransientObjectException during Criteria.list()

    - by rancidfishbreath
    I have seen posts all over the internet that talk about how to fix the TransientObjectExceptions during save/update/delete but I am having this problem when calling list on my Criteria. I have two objects A and B. A has a field named b which is of type B. In my mapping b is mapped as a many-to-one. This all runs in a larger persistence framework (the framework is kind of like Core Data) and so I don't use any cascades in my hibernate mappings since cascades are handled at a higher level. This is the interesting code surrounding my criteria: A a = new A(); B b = new B(); a.setB(b); session.save("B", b); // Actually handled by the higher level session.save("A", a); // framework, this is just for clarity // transaction committed and session closed ... // new session opened Criteria criteria = session.createCriteria(A.class); criteria.add(Restrictions.eq("b", b)); List<?> objects = criteria.list(); Basically I am looking for all objects of type A such that A.b equals a particular instance of b (I actually tried restructuring a query so that I was passing in the id of b just to make sure that b wasn't causing me problems). Here is the stack trace that occurs when I call criteria.list(): org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: B at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:244) at org.hibernate.type.EntityType.getIdentifier(EntityType.java:449) at org.hibernate.type.ManyToOneType.nullSafeSet(ManyToOneType.java:141) at org.hibernate.loader.Loader.bindPositionalParameters(Loader.java:1769) at org.hibernate.loader.Loader.bindParameterValues(Loader.java:1740) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1612) at org.hibernate.loader.Loader.doQuery(Loader.java:717) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:270) at org.hibernate.loader.Loader.doList(Loader.java:2294) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2172) at org.hibernate.loader.Loader.list(Loader.java:2167) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:119) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1706) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:347) Here is my mapping: <class entity-name="A" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> <many-to-one name="b" entity-name="B" column="b_id" lazy="false" /> </class> <class entity-name="B" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> </class> Can anyone help me figure out why I would be getting a TransientObjectException during a fetch? Preferably I would like to find a solution that does not rely on cascades since they tend to mask problems that occur in the higher level framework.

  • still need smarty syntax highlighting in Eclipse PDT

    - by pocketfullofcheese
    How do I get smarty syntax highlighting in Eclipse PDT? The only project I was able to find is SmartyPDT, but it's outdated and isn't working with my current Eclipse install (PDT All in one, with Eclipse 3.5). EDIT: I recently found this post asking the same question from a long time ago. But the plugin linked in the accepted answer there is out of date now. EDIT: removed "(no accepted answer)" from title. it was misleading.

  • How to detect that an Html element is in View?

    - by Olaseni
    Using Jquery preferably, how do I detect if an element is within the viewable client area of a browser? I'm dynamically creating a menu from a dataset, and when the list grows too long, the height of the resulting menu causes part of it to fall below the browser bottom client area. How do I detect this and act accordingly?

  • smallest filesize for transparent gif

    - by zaf
    I'm looking for the smallest (in terms of filesize) transparent 1 pixel image. Currently I have a gif of 49 bytes which seems to be the most popular. But I remember many years ago having one which was less than 40 bytes. Could have been 32 bytes. Can anyone do better? Graphics format is no concern as long as modern web browsers can display it and respect the transparency.

  • How to output LogCat to Console?

    - by Shooshpanchick
    Is there a way to make LogCat's output to appear in Console view in Eclipse? LogCat view is much less convenient that Console, because it's hard to see long messages in it (they are trimmed by column border) and there are no clickable highlighting in exception stack traces to quickly navigate to source of error.

  • Is a degree in Industrial engineering helpful for programmers

    - by Shailesh Tainwala
    Hi, I am currently pursuing my MS in Software Engineering. I am considering the option of doing a part time programme in Industrial Engineering as most of the courses (Operations Research, Accountancy, Business Process etc) are those that I do not have any knowledge in. Is there a requirement in the industry for people with such qualifications? My long term career goal is to manage software projects that enable clients to increase productivity.

    - by Glenn Slaven
    Our server returns a custom 'X-Execution-Time' HTTP response header that returns in miliseconds the time between the server getting a request and our code returning a page, ie how long our code takes to run. I'm using JMeter to do some testing & I'd like to be able to report on this number of over time. I've setup this regular expression extractor: X-Execution-Time:\s(\d+) but I don't know how to get JMeter to report on this number per request so i can get a trend over time

  • Any other kinds of "Task Queue" APIs ?

    - by sork
    I'm curious if it's common practice outside of the GAE platform to be able to defer tasks to background workers via webhooks. I find it particularly useful to speed up the front-end of webapps, by delegating any long process to background tasks. I'd like to hear about open source software allowing to implement a TaskQueue-like API, with webhooks preferably, if anyone has some experience in this area. Thanks!

  • How do you optimize stunicholls' "Professional dropdown #2" with jquery?

    - by geff_chang
    Link to menu: Professional dropdown #2 I was wondering if these posts Suckerfish meets jQuery or Son of Suckerfish dropdowns in jQuery could optimize the menu above. I need the menu to be optimized for IE6, because when I use the menu as it is, the menu hangs after I click on a menu item that loads a page with heavy processing. It takes too long for the menu to be enabled again. Any ideas?

  • Simulating MySQL's ORDER BY FIELD() in Postgresql

    - by Peer Allan
    Hello all, Just trying out Postgresql for the first time, coming from MySQL. In our Rails application we have a couple of locations with SQL like so: SELECT * FROM `currency_codes` ORDER BY FIELD(code, 'GBP', 'EUR', 'BBD', 'AUD', 'CAD', 'USD') DESC, name ASC It didn't take long to discover that this is not supported/allowed in Postgresql. Does anyone know how to simulate this behaviour in Postgres or do we have to pull to sorting out into the code? Thanks Peer

  • XQuery method question, trying to sum values read from xml

    - by Buck
    I'm pretty new to XQuery and I'm trying to write an example function that I can't get to work. I want to read an xml file, parse out the "time" values, sum them as they're read and return the sum. This is trivial and I'm looking to build more functionality into it but I'd like to get this working first. Also, I know there's a "sum" directive in XQuery that would do just this but I want to add more to it so the built-in sum is insufficient for my needs. Here's my funtion: bool example(Zorba* aZorba) { XQuery_t lQuery = aZorba-compileQuery( "for $i in fn:doc('/tmp/products.xml')//time" "let $sum := xs:integer($i)" " return $sum" ); DynamicContext* lCtx = lQuery-getDynamicContext(); lCtx-setContextItemAsDocument("temp_measurements.xml", lDocStream); try { std::cout << lQuery << std::endl; } catch (DynamicException& e) { std::cerr << e.getDescription() << std::endl; return false; } catch (StaticException& f){ std::cerr << f.getDescription() << f.getErrorCodeAsString(f.getErrorCode()) << std::endl; return false; } } It's called with an appropriate main(). If I comment out the line that starts "let $sum..." then this works in that it returns the time values as a series of integers like this: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3.... Input file looks like this: <?xml version="1.0" encoding="UTF-8"? <temps <temp <time0</time <lat0</lat <long0</long <value0</value </temp <temp <time1</time <lat0</lat <long1</long <value0</value </temp ...
