I am getting the error at the point I try to save an entity. I only get this error when I have booted up my server, not when I run my unit tests using dbunit.
I am trying to save an association. My unit test should be the exact same condition as that which I am encountering when manually testing. I am adding a new entity on one end of the relationship where no relationships existed before.
I am using HSQLDB with the unit tests and the web app is using SQL Server.
The searches I have performed have not proved fruitful. An explanation of the message would prove very useful.
Here is the test case (that works just fine!):
@Test
@DatabaseSetup(value="MobileWebsiteTest.saveMobilewebsiteMobilecolorswatchmapuserdefined_NewUserSwatch.xml", type=DatabaseOperation.REFRESH)
public void saveMobilewebsiteMobilecolorswatchmapuserdefined_NewUserSwatch() {
// given
Integer mobileWebsiteId = 569;
Mobilecolorswatchmapuserdefined expected = MobilecolorswatchmapuserdefinedBuilder.init().build();
// when
Mobilewebsite result = service.saveMobilewebsiteMobilecolorswatchmapuserdefined(mobileWebsiteId, expected);
// then
assertNotNull("The Mobilewebsite user defined swatch should not be null", result.getMobilecolorswatchmapuserdefined());
assertNotNull("The Mobilewebsite user defined swatch id should not be null.", result.getMobilecolorswatchmapuserdefined().getMobileColorSwatchMapUserDefinedId());
assertEquals("The result aside property should be equivalent to the expected aside property.", expected.getAside(), result.getMobilecolorswatchmapuserdefined().getAside());
assertEquals("The result SiteName property should be equivalent to the expected SiteName property.", expected.getSiteName(), result.getMobilecolorswatchmapuserdefined().getSiteName());
}
Here is the service (note: I am currently doing a delete/save under the condition that there is already an association - this should be one-to-one, but is legacy):
@Override
@Transactional
public Mobilewebsite saveMobilewebsiteMobilecolorswatchmapuserdefined(Integer mobileWebsiteId, Mobilecolorswatchmapuserdefined related_swatchmap) {
log.debug("saveMobilewebsiteMobilecolorswatchmapuserdefined(Integer mobileWebsiteId=[" + mobileWebsiteId + "], Mobilecolorswatchmapuserdefined related_swatchmap=[" + related_swatchmap + "])");
Mobilewebsite mobilewebsite = mobilewebsiteDAO.findMobilewebsiteByPrimaryKey(mobileWebsiteId, -1, -1);
Calendar now = Calendar.getInstance();
if (mobilewebsite.getMobilecolorswatchmapuserdefined() != null) {
this.deleteMobilewebsiteMobilecolorswatchmapuserdefined(mobilewebsite.getMobileWebsiteId(), mobilewebsite.getMobilecolorswatchmapuserdefined().getMobileColorSwatchMapUserDefinedId());
}
related_swatchmap.setCreatedDtstamp(now);
related_swatchmap.setLastUpdatedDtstamp(now);
related_swatchmap.addToMobilewebsites(mobilewebsite);
**related_swatchmap = mobilecolorswatchmapuserdefinedDAO.store(related_swatchmap);**
mobilewebsite.setMobilecolorswatchmapuserdefined(related_swatchmap);
mobilewebsite = mobilewebsiteDAO.store(mobilewebsite);
mobilewebsiteDAO.flush();
return mobilewebsite;
}
The stack trace points to the highlighted line above: mobilecolorswatchmapuserdefinedDAO.store(related_swatchmap);.
The stacktrace is:
