How to display back to back warning message in H5 script?

I am trying to give back to back warning messages using H5 script on OIS101/B panel.If order contains 7 lines and out of which 3 lines contains erroneous data,then script is trying to display 3 warning messages back to back,but currently facing issues while doing this only able to see last warning message,as this overlapping the first 2 warning messages?How to handle this scenario in H5 script?

It's not clear to me what method you are using to show a message but basically what you need to do is to concatenate the messages. Say that you have a list of messages and then based on the number of messages you add show only one message with the information combined like:

There are x lines with issues. + Message 1. + Message 2.

If there is only one line then you return just "Message1".

If there are a lot of lines then you would have to change into something shorter, like "There are x line with issues" Please verify line number: 1,4,10,23.

If you are just showing a dialog on each error you encounter the dialog will just be stacked on top of each other as there is no magic in the framework that would combine individual message into one.

If the calls to validate a line is asynchronous you would need to trigger them in sequence or wait for the last one to complete before showing the message by keeping track of them individually.

Hi ,

Thank you for the suggestion,here in script I m calling 4 different API transactions to get the required data ,in case of multiple lines because of asynchronous call to MI or asynchronous response i am getting wrong value as output,

In this case suppose if OIS101/b panel contains 3 lines then it should process complete flow for 1st line,then for 2nd line and then 3rd,but this not happening.Is there any method where we can handle MI calls synchronously?

Thanks,

No, there is no synchronous API to call a backend. The issue is on your code. So you are calling 4 APIs per line? That is a lot of calls to be making. You should show a progress indicator or something as you are making all those calls and you need to trigger the the next call in the completed handler, if you have dependencies between the calls. With a dependency I mean that you need output from one call to the next. If you just want to execute stuff in parallel then use promise.all.

The MIService.execute returns a promise, you can chain the call manually by not calling the next until the first is actually completed and the promise is successfully completed. If they have not dependencies I would run each batch per row in parallel and use the promise all to get a callback when ALL are completed.

There is a lot to read in this area if you for example search for "wait for all promises to resolve". But if you want to start easy just read up on promises in general and be sure to handle the success and the failed scenario and call the next MI-execute when the first one is completed.

Greetings;

You can call the APIs in a function, and in that function do an await for them all to complete like Karin suggested. You can use promises or await, depending on your code style. I have several updates I do in a loop with an await on the function for the various data parts to return.

As for notification, or keeping the program from advancing, I've put my API calls in a sub function that I call and then put a message on the M3 bar at the bottom showing I'm processing API calls. I then I subscribe to the event for F3 or Next (or whatever is relevant for this function) and prevent the panel from being advanced or exited while the APIs are processing. If I run into any issues, I display an error dialog. Since I trigger off the F3 or F18 in this case (if they don't wait for the API to complete), I intercept the call, and when the API is complete, I just press the button again if there were no errors.

Example:

Subscribe to onRequesting...

Intercept Key Press...

Advance if successful (or stop if failed, not shown)

I sometimes have to find where the best place to await is for the various calls, but it's worked well for me so far. Hope this helps;

Hi Billy,

I found your solution working in my case and it helped me.

I have a query Is there a way I can detect error message on a panel?

When enter is clicked on the program and if there is any standard M3 error message returned I want to call an API.

I am not sure if there is panel.state.messageid function in H5 script to handle this. (In smart office script it was possible to do with OnRequestCompleted and panel.state.messageid ).

Thanks,

Jags

no there isn't panel.state.messageid on H5

You can also made sync calls on API's.

The only problem is in MT that You should have a tokein also (30s interval)
