Unable to perform create/edit/delete operation in SAPUI5 CRUD Application

[Former Member]

Hi Experts,

I have created a sapui5 CRUD application following the below link as a reference.

https://www.youtube.com/watch?v=wA_lK93PDU4#t=936.452018

I am able to create a new ticket but unable to save the same.

Further I am not able to perform edit and delete operations also.

Below are the exceptions I am encountering:

1. Cannot read property 'getBindingContextPath' of undefined on clicking the delete button.

2. Uncaught TypeError: oTable.getSelectedIndex is not a function on clicking the edit button.

3. Uncaught [object][object] on creating a new ticket and clicking the save button. Also the server responded with 405 error in POST method.

Please provide your suggestions as to where I could have gone wrong.

Thanks,

I have narrowed down to the place where I am getting the error. I my Product.controller,js I have a code "OData.request(requestObj, function() )" which shows an error "OData is undefined".

Any suggestions on resolving it would be helpful.

you can use jquery or odatamodel to send the ajax request. don't use that odata

do some google....

not able to find this getBindingContextPath in your code.

Hi Jun,

On following some block I had edited the code from var selected = oTable.getSelectedIndex();

to var selected = oTable.getBindingContextPath();

Still facing the same issue.

I am not sure if this is the correct method. I have attached the original code from a reference scn blog.

your code looks ok....

[Former Member]

Yeah on exploring few blogs I seem to be ok with the code. But still I am not able to perform these CRUD operations.

[Former Member]

Any suggestions from your side Jun. It would be very helpful.

[junwu]

Have you tried to replicate the same scenario using SAPUI5 CRUD Master Detail template?

In that CRUD Application I am again unable to create a new ticket. Futher to it the changes done for a particular ticket is not persistent.

The changes are not saved when I navigate to another screen and the visit the edited ticket.

Any information regarding this from your side?

[junwu]

what error you have this time?

[Former Member]

While creating a new ticket and giving the mandatory details -> saving it I get the below error.

Sorry, a technical error occurred! Please try again later.

Is this because something is wrong with my application or a bug in the template.
