In my JSF based web application I have large number of UI input fields on the forms. I try to save the data in to managed beans(and propagate to the database) by submitting the form via ajax calls while the user is still entering the data on the form. When I have validation errors on the page the ajax submit fails to save data to the backend. The usual validation error is required validation on the input fields. This is an annoying issue for me since if the validation of 50th input field fails the data entered in the first field is also not saved.
In all of UI forms we do have a summary page where we show the user entered data before allowing to submit the form. What I would like to know if it is possible to delay the form data validations until the user goes to the summary page. On summary page I want to either display the validation errors or display the read only version of the data. Did anybody encountered this situation or have a solution to this kind of problem?

There is a sales order record in edit mode.I use window.location.reload() to refresh current page in cilent script after edit some fields value.Then all the data are restored.If I want to reload current page without losing any form data,how to do it?
you can get values which are changed using field change function. Then before reloading function load the record and set the values which are changed and then save the record object.
Actually, we have to understand the functionality and flow of the script first.
Before submitting the record, the data is at the client side ONLY. And to persist the data, you need to save/commit the data in to the Netsuite database.
As soon as the refresh button is hit, it fetches the data from the Netsuite database (which makes sense) and populate the data on to the page.
I hope it clears.
All the best.
I found that refreshing a submitted form results in processing the form data again. In some other CMS's I've used, repeated submission pops up a warning (e.g. "You have already submitted this form, are you sure you want to submit it again?").
What's the right way to address such cases in Orchard? I.e. prevent repeated processing of form contents, and/or warn about repeated submission.
#BertrandLeRoy confirms that redirect after submission is the correct way to handle this case in Orchard. Thanks!
Im making an Xpages application which needs to have server-side validation.
In my form, when a field is cleared and the form submitted - if there is another field which causes the validation to fail - it will be repopulated with the last successfully saved value in the document.
This is not what should happen. The field should stay blank until the page is either refreshed, or the user enters another value.
Does anyone have any idea about what is causing this to happen?
Thanks,
Paul
This depends on your execId and refreshId.
For what happens during partial refresh, read these blog posts, particularly part three http://www.intec.co.uk/tag/partial-refresh/.
If validation (or conversion) fails server-side, the server-side map of the XPage is not updated because the data is not deemed complete enough for server-side processing.
So the partial refresh skips to Render Response, which posts back what HTML should be displayed to the page. That includes values in fields - you're replacing HTML, so it has to.
If you're save button is refreshing the form area, you'll be replacing the HTML there, so overwriting the values entered by the user with the last valid values.
The recommended approach will depend on your page architecture and what you're saving. One is to move validation to the save() function, by which time the values will have been updated in the DominoDocument (the front-end wrapper for the Document on the server). Another is to only refresh the validation area and, if validation was successful, call context.reloadPage() or context.redirectToPage() to effectively skip the partial refresh.
Thanks for the help. As far as I can tell, it was simply due to the way the default converter included with xpages handles the object and/or string. Writing a java custom converter sorted everything out.
I want to design an infopath form in which there is a repeating table. This table gets data loaded into it on form load using a web service (to receive data). the thing is that user must be able to modify this data and send it back to the server on form submit using another web service (to submit data).
Now I need something like multiple bindings so that the control is bound to to the web service data source to receive data, and also to the form data source in order for the other web service (submit) to send the form data to the server.
I tried to do this with a single value control (not repeating value) and I managed to do that by binding the control to a form data source field and setting the default value of the field to my web service (receive) field. But I can not do that for a repeating table because each time the form loads, I get a table with one row (no matter how many rows the web service returns), filled with the data of the first row returned by the web service, and clicking add row button would result in another row with the same data of the first row.
please help me. thanks.
I found the solution myself. I have to put a repeating table on the form and bind it to a form field. With the web service data source to pull data, I add some code behind to the form load event to set value of the field (which is bound to repeating table) with the data I pulled from web service data source. The code is pretty simple and you can find a lot of threads demonstrating that.
In my case, it was a sharepoint site which I wanted to deploy the form to. There are difficulties to deploy an infopath form with code behind to a sharepoint site. "Nader" has a really useful post with an step by step procedure for doing this:

I'm developing adf calendar events form where the main page displays the calendar when user click on any date a small form appears to enter event details. I did most of the work but I'm facing a validation problem, I want when user save the form it checks if a field has a value and contains a number other than zero to save the form to the database if it has a zero it displays an error message, I hope you got the idea.
Note: I set ActionListener = #{bindings.Commit.execute} to the save button, I'm wondering if I can execute the validation when execute commit.
Regards,
create an IMPL file and override DoDML. You can then decide whether or not to update the database with the change. For a similar sample, see

From the entity impl you have access to its attribute for your 0, 1 comparison
You can. The those validation should be added to the entity object. Generate it as Java with all accessors and so on. In that class you can add validators.
If you want you can add a backing bean and a value change listener to the ADF component and do some checks there as well.
But the common consent is that pre-commit validations should be added to the entity object.
