Facing error in example of dhtmlxDataStore

Suite and Optimus Suite 5
#1

I am facing javascript errors.Errors are shown below.

Further I am attaching entire war file with this.
I am trying to access page “testWebProject1/testHtml2.html” of deployment.
testHtml2.html page internaly calls servlet “masterServlet.java” through url “do.masterServlet”.
I am developing application using eclipse and deploying the same on jboss.

I have tried to replicate example given on link :
docs.dhtmlx.com/doku.php?id=dhtm … erver-side
In this example, php is used.I just changes necessary url to that of servlets.

I have included dhtmlx script which I had downloaded from site.
I am not able to understand why I am facing these issues.Please help.

Most probably - incorrect format of the incoming data is the reason of the problem.

In java files you are using - GridConnector , but for datastore you need to use JSONCommonConnector

Hi thank you for prompt response.

I replaced “GridConnector” to “JSONCommonConnector”.
I am still getting below mentioned javascript error:

please let me know if i am using improper version of “dhtmlx.js” or any other issue.

Probably caused by grid’s configuration.

myGrid.setHeader("Name,#cspan,Department");
myGrid.setInitWidths("74,71");

you have 3 columns, but providing sizes only for 2 of them, try to change it as

myGrid.setHeader("Name,#cspan,Department");
myGrid.setInitWidths("74,71,150");

Thank again for keeping with me…

But problem has not resolved.
I have done changes suggested by you and still I am getting javascript error.
