Widgetset does not contain implementation...

Eugenio Bargiacchi

Hello, I've been trying to fix a problem in this last week, unfortunately to no avail.

I'm trying to use this addon: https://vaadin.com/directory#addon/locationtextfield, but the actual field is not rendered, and instead I get this message:

"Widgetset does not contain implementation for org.vaadin.addons.locationtextfield.LocationTextField. Check its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:
-Unrendered UIDL
-org.vaadin.addons.locationtextfield.LocationTextField(NO CLIENT IMPLEMENTATION FOUND) id=PID2 width=100.0% immediate=true caption=Address: pagelength=10 filteringmode=0 totalitems=0 textChanged=true iem=LAZY iet=1000 eke=true
-variables
selected=
filter=
page=0
ltfFilter=
-options"

I'm using a ton of other addons, and they are all working correctly. I've tried looking at similar threads but I didn't seem to find a solution that worked for me.

I'm using Eclipse, if this can be useful.

Thanks in advance for any help.

In case you are not familiar with Vaadin widgetsets, first read this page and/or the corresponding chapter in the book.

Make sure you have compiled your widgetset, refer to it in your web.xml and all caches are refreshed. Compile the widgetset with verbose mode enabled to see more information about what is included in it.

Thanks for prompt reply.

GWT compiler compiles fine without any warnings or errors.

Based on the verbose output, Refresher and ImageScaler are included in the widgetset but LocationTextField is not.

My initial suspicion would be that the client side source code of LocationTextField is not on your widgetset compilation classpath. Unfortunately, you cannot modify the widgetset compilation classpath directly in Eclipse so if the sources are not in the same JAR as the classes, you either need to modify the JAR (taking care that the manifest stays as the first entry - preferably working with "jar" instead of other archive management tools) or create a separate launch configuration for running the widgetset compiler class directly with your customized classpath.

Another possibility would be missing dependencies or their client side sources for LocationTextField.

Thanks Henry for the reply.
But I dont know how to go about doing what you suggested. Please elaborate on those steps.

thanks.

Sorry, no time now to go into details.

If LocationTextField really is the only problem:

Check whether the main JAR of LocationTextField contains *.java source code files e.g. with "jar tvf locationtextfield.jar". Then contact the author in this thread. It seems to be built using and for Maven so maybe the source code is not in the JAR but in a separate JAR where Maven projects can find it but the "Compile widgetset" button in the Eclipse plug-in doesn't.
