Resetting a form to its original values

Does anybody know of a way to reset a form to its original values? In some cases JSF is displaying the last used form values, even after navigating to a different page and back again, instead of re-reading the values from the relevant backing bean.
I'd imagine it involves iterating through the tree of UIView objects, but if anybody has some sample code that would much appreciated (and if anyone from the EG is listening, some kind of resetValues() method would be a useful addition to the API).

Each page in creator gets an AbstractPageBean which extends FacesBean and that contains the erase() method. This clears the state of the page forcing a reload of the page components. The docs make the following comment.
"Erase previously submitted values for all input components on this page. This method MUST be called if you have bound input components to database columns, and then arbitrarily navigate the underlying RowSet to a different row in an event handler method."
I find this comment very strange indeed. First, why hardwire you GUI to database components? What's the upside? It's not convenience because you can automate creation of datamodels from the database then do your binding. That aside, why hardwire the documentation to the database? Why not say "if the underlying state of bound variables changes independent of the UI you must call erase to relaod the change values". Anyhoo, I digress.

  • Reset Picklist Options to its original Values

    Hi,
    Is there a way to reset picklist options to its original values (when the page initially loaded) in CRM 2013/2015?
    Depending on some business logic, I am removing some of the options from the picklist. Since in CRM 2011, after each save, the page was reloading, all the initial values were coming back and based on my logic I could remove some.
    But in 2013/2015, since the page is not reloading any more, after i remove some of the options the first time, they never come back. Is there any way to get them back without explicitly adding them back in JavaScript?
    Basically what I need is a mechanism to reset the picklist to its original state with the options available when the page got loaded.
    Is there a method that would reset the picklist?
    Thanks.

    Thanks for your reply.
    I have tried this already. The problem is I do not want to call save from within my JavaScript. And if I use the following command: 
    Xrm.Page.data.refresh(false);
    It does not reload the page and does not bring optionset original values.
    Thanks,

  • CO - After cost revaluation is it possible to see its original value?

    Hi SAP consultants !
    After cost revaluation is it possible to see both: the new cost (revaluated) and its prior value (before revaluation)? Despite I think it is not possible I searched for such information in some tables (COEJT, COEJL,  COEPL, and others) but find nothing.
    Thank you all,
    Naej

    Eli, Matej thanks for your input. My question is pretty much answered as for as CO-CCA is concerned, in that it cannot be done.
    As for this requirement, I have decided to go another route in entering customer forecast data by using CO-PA. Entry of customer forecast data via SD schedule line (with MRP turned off) and having that data transferred to CO-PA.
    Thanks again,

  • Repleting a value to its original value after depletion

    In my class I have:
    public int charge;This holds a value which set by me in the constructor when I instantiate the class in main(). This value represents a battery, and the value I give it at the start of my test represents a full battery. As the code runs, the value of charge is depleted incrementally (charge--). When charge equals 0, it requests the Charger class to "recharge" the battery and restore the charge to its value, which I assigned to it at the beginning.
    In my test, I will instantiate the class with the charge several different times, and I will assign each object's charge a different value since all batteries are not made equal and some last longer than others. However, what I am stuck with is figuring out how to use the recharge() method I have in my Charger class to completely restore the battery instantly (and not incrementally as it was depleted). Any ideas on what the recharge() method should look like?

    In your code you have:
    Charger charger;Later on you try to use charger. This should give you a null reference error, not a syntax error. If you have charger created someplace else, that statement overrides its declaration in the external scope and creates a local variable to hold a reference. You do not initialize that variable with any reference to an external object, nor create one in the scope.
    My way of thinking you need 3 classes:
    1 - Battery
    2 - Charger
    3 - Device (to use the Battery or consume the charge).
    The Battery will need to be used by the other 2 classes, as such, you need to be able to pass a reference of Battery to those. To do that you need your methods to accept a reference to Battery. This will make your Charger and Device classes able to work on all of your Battery objects.
    public void recharge(Battery b){
      b.currentCharge = b.maxCharge;
    public void useEnergy(Battery b){
      b.currentCharge -= 3; //some drain amount, I arbitrarily chose 3.
      if(b.currentCharge<0) b.currentCharge = 0;
    }

  • Will all of my downloads be deleted if In reset Firefox back to its original default?

    Firefox is slow to start and when it does the system will lock up and I receive a message that "Firefox Mozilla is not responding" This is happening quiet frequently, everyday actually. I want to restart to see if this will fix the problem and I've read your articles and what will be deleted but I'm still not clear on a couple of issues.
    1. Will all my downloads, i.e., pictures, resumes, etc be deleted if I reset?
    2. I have just downloaded a new security system. Will this be deleted?
    3. I understand about the saved history and tool bar which I can re-install.
    4. Is there any way to speak to a technician by telephone?
    Your prompt response is appreciated. Tony Morales

    Files that you have downloaded will always be stored in the folder where you saved them an the actual files will never be removed when you reset Firefox.<br />
    I don't know for sure if you keep the download history as part of the history that is imported when you reset Firefox.<br />
    What kind of issues do you have with the current Firefox profile folder that you want to reset Firefox?
    Is that only that Firefox takes long or too much time to start?
    Did you try Safe Mode?
    *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
    It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

  • Resetting a form to default state

    I have a form with lots of swing components(JtextFields,JRadioButtons,JComboBoxes), and I want to be able to "reset" the form back to its' original state(i.e. blank textfields,no selected radiobutttons,comboboxes with defaults showing). Is there a single method to update the entire form to its' original state? Thanks.

    hello,
    done this before,
    what i did was, i create a function, in this function i have all the add functions i.e adding the objects to the container. everytime i want to reset the form, i call the removeAll() function which clears the frame from all components and then i call the function that adds the components to the frame example
    public someClass()
    addComponents();
    //actionPerformed method for a button that resets
    this.removeAll();
    addComponents();
    public void addComponents()
    //add all the stuff to the container
    }hope it makes some sense

  • Problem of h:selectOneMenu it is popping back to original value

    I have a dataTable in which one column is a <h:selectOneMenu> and the required attribute is false.
    There is a inputText in another column and the required attribute is true.
    Whenever I change the <h:selectOne> option to null (that is blank option) from a string option and delete the inputText box value and click the submit button the
    <h:selectOneMenu> jumps back to its original value though I placed the required to false and a required message for inputText box.
    Required Message that pops out for inputText is expected but the <h:selectOneMenu> popping back is not desired. How can I avoid it.

  • How do I restore an image back to its original form?

    Is Aperture 3 supposed to be non-destructive? If so, how do I restore an image back to its original form? I'm out of undo's and I need to get rid of some stuff.

    You have a few choices here
    1. The "m" key will show you the master image without adjustments, not remove them;
    2. Right click an image and using the contextual menu, select reset all adjustments, removes them;
    3. Same menu, create new version, allows you to have multiple versions each with unique adjustments, B&W, cropping etc.

    No, Forms cannot be compiled into an .exe. But an Oracle9iAS Enterprise Edition install contains everything it needs to run.
