openlayers 2 - String update - only first character gets stored


Client: OpenLayers / Server: Geoserver


When I update a WFS Element,


JAVASCRIPT:


element.feature.attributes.ENAME = "Mystring";
saveStrategy.save();


HTTP-POST:


 
ENAME
MyString


some features of Type String do not get fully updated, only the first letter ends up in the WFS layer.



...


M


//only M ends up on the server, not Mystring as expected

the respective line in the logfile (catalina.out) says:


        name = ENAME
value = Mystringproperty[0]:


strangely, the attached property[0] is on all attributes, not only on the one which is reduced to its first letter, but also on some strings that do not get shortened as well as some integers.


I would expect the type of the respective feature to be something like String[1], but as far as I can see the Type System, there are no length attributes to Strings.


Who knows what I can do?




UPDATE




When I change the value of any feature's attribute (ENAME) with OpenJump and upload the changed data, my application shows the feature correctly, which means, the geoserver itself CAN store a string longer than 1 in the respective attribute.


However, everytime I make an update via OpenLayers, regardless on which feature, any other feature's ENAME attribute gets shortened (like from 'MyString' to 'M'), even if it was a totally different feature that was updated on OpenLayers.


The log (catalina.out) says NOTHING about this perfidious update operation.

STILL not solved


WFS Layer:






Javascript definition:


layer_selectable = new OpenLayers.Layer.Vector("WFS", { strategies : [new OpenLayers.Strategy.BBOX(), saveStrategy], styleMap: new OpenLayers.StyleMap({ 'default': style, 'select': style_selected }), protocol : new OpenLayers.Protocol.WFS({ url : geoserver + config.wfs_layer, version : "1.1.0", featureType : "Graeber", featureNS : config.featureNS, srsName : epsg, }), renderers : renderer //tileOptions: {crossOriginKeyword: 'anonymous'} });



Answer



You could edit your WFS-T Service directly with QGIS for example to see if it's an error of your javascript-application or of geoserver itself.


http://docs.qgis.org/2.2/en/docs/user_manual/working_with_ogc/ogc_client_support.html section "WFS and WFS-T Client" ( or in german: "QGIS als OGC Datenclient")


In QGIS you could also check which limit is set for the character-length of the column that gets cut off (in Layer-Properties):


feldlaenge


Have you considered importing the shapefile to postgis and then publish the layer directly from an postgis-store?


If you like to you can post the javascript-code on http://jsfiddle.net/ or http://www.codeshare.io/


The Content of the Firebug Post TAB and Content of the respective Log Section you posted shows different versions(1.0.0 vs. 1.1.1):



and logfile:
2015-01-20 17:01:00,671 INFO [geoserver.wfs] -
Request: transaction
service = WFS
version = 1.1.0

but I guess these were two different tries, weren't it?
