See the FAQ and the Debugging overview in the docs to understand the information you need to post to make it possible to help you.

Among other things you didn't post what product and version and browser you are using, contents of the Developer Console, RPC tab contents, etc.

• FireFox51.0.1(32) & Windows 7
• Tomcat 7

Thanks for your reply.i'm using demo showcase supply in smartgwtee-eval-6.0p package,i run showcase.war in tomcat 7
1、 I visit http://localhost:8087/showcase/showc...lder/index.jsp.
2、 By Draging VLayout,ListGrid,DynamicForm,Button,DataSource(animals datasource) .a perfect screen was designed ,and data was loaded,
then i saved 2 files,project_animal.proj.xml and demo_animal.ui.xml , the two files auto generated in:
F:\Tomcat7\webapps\showcase\showcase\tools\visualBuilder\workspace

3、 Unfortunately,when i click Run ,nothing happend ,even i open dev console,i found these logs below:

Isomorphic hi,for dig into the problem,i import a sample ds-hibernate to intellij ,run the visual builder,finally i found an server error :

 Caused by: java.lang.Exception: Unable to find project: null
    at org.apache.jsp.hibernateds.tools.visualBuilder.projectRunner_jsp._jspService(projectRunner_jsp.java:150)
    ... 35 more
   [WARN] /hibernateds/tools/visualBuilder/projectRunner.jsp
java.lang.Exception: Unable to find project: null

i found that

project = Project.[I]load[/I](projectName);

return Null,and workspaces/ directory was not generated in below path:
C:\Users\Administrator\AppData\Local\Temp\jetty-127.0.0.1-8888-www-_-any-\jsp\org\apache\jsp\hibernateds\tools\visualBuilder\

[Isomorphic]

So it fixes the problem if you add the "workspaces" directory? This sounds like your IDE may have decided to skip generating "workspaces" since it's an empty directory, so perhaps we need to put a "readme" file or similar to force the directory to be created.

Isomorphic ,hi,Unfortunately,it's not work when i click "Run" button even "workspaces" created.
url:

 http://127.0.0.1:8888/hibernateds/tools/visualBuilder/projectRunner.jsp?type=project&project=%5Csupplyitem

and printscreen:

Isomorphic hi,Isomorphic,in another way,for test Visual Builder ,i run start_embedded_server.bat in smartClientSDK(SmartClient_v110p_2017-03-11_Evaluation),after do the same thing, it's also doesn't work..i'm confuse about the code

project = Project.[I]load[/I](projectName);

,and i can't add a breakpoint in projectRunner.jsp,so i can't findout more details

[Isomorphic]

You would need to ensure that the "workspaces" directory already exists before saving.

Also, where do you see the project file (".proj.xml") being saved? And what settings do you have in server.properties (which potentially configured where project files are stored)?

[mayun]

Isomorphic

I 'm using the smartClientSDK,here i wiil show you the steps with screen shot


1、in visual builder window,i click right top button "Run"


2、after click "Run" button,so i check the cmd window,found below error as same as before i post


3、 cmd window,opened by click "start_embedded_server.bat"

4、see the path

Isomorphic hi,Isomorphic,any suguestion? :cool::cool:

[Isomorphic]

We see the issue and are looking into a solution.

[Isomorphic]

We've fixed a few different problems, including one that's Windows-specific, in SGWT 6.0p to resolve your issue with VisualBuilder file loading. The fix should be in the nightly builds dated 2017-04-05 and beyond.

Similar fixes have been ported to SGWT 6.1d and SGWT 5.1p, but those will be in the nightlies dated 2017-04-06 and beyond. We're still investigating a SGWT-6.1d-specific problem related to your use case - we'll update this thread when that's been resolved.
