DMI Validation

[Rdamario]

We am using SmartGWT power 2.4

I created a serverside DMI validation. It presently just returns the condition false and sets the error message.

On the client side we've defined a form with items which come from the datasource. When we issue a validate the DMI validation is excuted and the error message is displayed on the console. The return from the validate call will always return true. If we issue a saveData on the form the validation is run again and returns errors but the save is allowed to continue.

I can't seem to get the validation to work so as to prevent the save. I also can't seem to have visibility to the error message from the client.

I've attached the ds and the DMI.

[Isomorphic]

Can you show the RPC requests involved (from the RPC tab in the Developer Console) and the server-side logs for the requests?

Note: this is always information we'll need for a problem of this kind.

What are you saying the problem is? Your RPC requests and responses show that the validation error prevented the save. You mention an "Add request which is done with the save" - this did not encounter a validation error, so it went through (as expected).

Also, the server logs are clearly incomplete.

[Rdamario]

when line 1 executes it returns true when the error on the console and RPC say that it is false. Should it not return false. If I don't use DMI and use a Range validation which would run on the client it works properly.

Another validate is done on save (line 2) which the RPC says is false but the saveData adds the record. I believed that because the second validation failed that it would not save and populate the ErrorMessage which I would be able to read with .getError() on the reponse.

1-> if (getForm().validate(true)) {
DSRequest requestProperties = new DSRequest();
String[] poNumbers = getPoNumbers();
String prompt = null;
if (poNumbers.length == 1) {
prompt = "Approving blockout " + poNumbers[0];
}
else {
prompt = "Approving selected blockouts";
}
requestProperties.setPrompt(prompt);

2-> getForm().saveData(new DSCallback() {
@Override
public void execute(DSResponse response, Object rawData, DSRequest request) {
Record responseData = response.getData()[0];
Record[] statusList = responseData.getAttributeAsRecordArray(PO_APPROVAL_FIELD_poStatusList);
PoApprovalReviewDialog myReviewDialog = new PoApprovalReviewDialog(new IpOkCancelCallback() {
@Override
public void onOk() {
doOk();
}
@Override
public void onCancel() {
doCancel();
}
});
myReviewDialog.setPoApprovalStatusList(statusList);
myReviewDialog.enable();
myReviewDialog.centerInPage();
myReviewDialog.show();
myReviewDialog.bringToFront();
}
}, requestProperties);
}

[Isomorphic]

DMI validators execute asynchronously since there's a server trip. The true value for validate() is just telling you that client-side validators passed, and an attempt to save to the server will happen if you call saveData().

[Rdamario]

How on the client side do a Test for this server-side validation and retrieve the error message if their is one. I need to be able to prevent the save from happening. Is their a callback I can use.

[Isomorphic]

saveData has a callback, and it normally fires only if there's no error, which is what you want. Note you can pass willHandleError:true via the DSRequest argument to indicate that you want to be called back even if there is an error.

[Rdamario]

Ok.

1) If server-side validations do not prevent saves(do not generate errors on the server-side response when update,add are executed), and its results are not part of validate() then what is it's ended use.

2) Should I code the validation call on the server-side when an add or update is done and put the error in the response.

Thanks in advance

[Isomorphic]

Validation prevent saves as your own logs show. That is their purpose. There is no need to add any more validation code than you have or than is shown in the sample.

The only thing you are doing wrong is doing a related save without checking whether the primary save was rejected due to your validation rules, and we just explained how to do that.
