unable to call read task and dependencies.

[Nagaraj]

I am trying to use gantt chart in a jsp file. I am using spring mvc and maven for the project. I was following the tutorial given in spring demos, but still I am not getting the result. Nothing is getting displayed in the jsp page. I have attached my jsp file and controller bellow. I also used debug mode to run the project but request is going only till /index method and no request is getting send to /gantt/tasks/read or /gantt/dependency/read  methods.

I dont know where I went wrong. could you help me find the error any configuration setting I might be missing.

Okay I had done some silly mistake i forgot to include the js and css files to my jsp. i have include it now. When i use debug mode it is retrieving the tasks and dependencies but it is not showing it in my jsp. I can only see the empty chart window. please somebody help.

Hello Nagaraj,

Could you log your traffic using Fiddler and send me the log file so I could inspect the data being returned from the controller's method for the tasks and the dependecies.

Hello Sir,

Thank you so much for replying to my post.

I have captured the screenshot on fiddler. I have attached it to this post.  I am using kendo ui for the first time so i am not sure where i went wrong.

 

Thanks and Regards,

Nagaraj.

Hello Sir,

I tried few more things to see whether I could work it out on my own. But am still not getting anything displayed on my chart.

I have attached the photo of my console and gantt chart to this post. Please have a look. I am using sql server 2008, hibernate and spring. 

I would really appreciate it if you could help me to solve this. 

 

Thanks and Regards,

Nagaraj

Hello Nagaraj,

I have inspected the provided fiddler log and the necessary resources are loaded correctly. Attached is a sample based on the provided implementation, which is working correctly at my end. Here is a video of the behaviour of the attached sample at my end.

Thank you so much for your reply sir,

 I have tried the same thing which you have attached in the sample. But still I am not getting any result.

I have captured the data while debugging. I have attached it to the post.

I dont know where i am going wrong even though i have followed the tutorial exactly.

I have also attached my fiddler capture to this post. I cant see  the json value of my tasks and dependencies. but still nothing is there on my gantt chart. I dont know why.

Thank you so much sir. I think I got the answer. I was assigning 0 value to my parent node. And there was no node with id 0. So nothing was getting shown on the chart. 

I really apologize for troubling you for this. I really appreciate your help.

Thank you so much.
