Hey all, I'm trying to fix InlineFeature support in Geoserver, and I tracked the problem down to a lack of CRS info on the created DataStore.
Basically, the StreamingRenderer didn't know which CRS to use to render the inline-supplied data, so it didn't get rendered at all. Fixing up a few things to get the CRS to appear in the MemoryDataStore got everything working ok for those folks who declare the SRS on their inline features GML, but some folks don't do that. I figured it would be a nice default to assume that they mean their features to be in the SRS of the WMS bbox (i.e. the "target" SRS for rendering). So I set about trying to figure out how to take a MemoryDataStore that has a featuretype.DefaultGeometry.CRS == null, and re-make it into a MemoryDataStore that has a featuretype.DefaultGeometry.CRS == bboxcrs. Re-creating the featuretype was fairly easy (using the FeatureTypeBuilder), the problem was moving the features from the old store to the new. Here was my attempt: //Step 1 -- create a query to fetch all the features from the // old store Query q = new DefaultQuery(build.getName(), Filter.NONE); //Step 2 -- get a featurereader from the old store FeatureReader ilReader = ul.getInlineFeatureDatastore().getFeatureReader(q,Transaction.AUTO_COMMIT); //Step 3 -- fill the new store up with re-typed features? MemoryDataStore reTypedDS = new MemoryDataStore(new ReTypeFeatureReader(ilReader,newFeatureType)); Problem is that this fails in the ReTypeFeatureReader. It seems that the retypefeaturereader is really a "re-order" featureReader. I.e., it fails if, for example, the attributetype of "SHAPE" in the original featureType is different from the attributetype of "SHAPE" in the target featuretype. See line 104 in ReTypeFeatureReader. Is this by design? Is ReTypeFeatureReader really just meant to re-order elements in the featuretype? I just want to re-type from one compatible featureType (with a getDefaultGeometry() == null) to another (with a getDefaultGeometry() == something). --saul ------------------------------------------------------------------------- Take Surveys.
