Calling Java Script function from java bean class in MAF

Hi

Sometimes you may get requirement to call javascript function from bean class, Use below invokeContainerJavaScriptFunction() to call the Javascript function.

doAlert() is JS function with one argument.

                                                                          new Object[] { " Absence Record Already Exist " });

Error while deploying MAF app to android - Cannot run program "\sdk\tools\zipalign"

Hi

If you are getting the below error while deploying the application to android. Here is the solution

[11:11:31 AM] Cannot run program "\sdk\tools\zipalign"": CreateProcess error=2, The system cannot find the file specified
[11:11:31 AM] CreateProcess error=2, The system cannot find the file specified

During the deployment jdeveloper creates .apk file using zipalign.exe file. But zipaling.exe is not exist in this location C:\Program Files\Android\sdk\tools\zipalign.

Solution is copy the zipaling.exe from   \build-tools\19.1.0  to \sdk\tools folder.

Convert input text Content to Upper Case or Lower Case

In this post i am going to talk about converting lower case data to upper case (or Upper Case data to Lower Case). There are multiple solutions to achieve this but i am showing there different methods.

1. you can use contentStyle="text-transform:uppercase;" on input text field.
        --text-transform:lowercase;
   
       
2. Using java script code

<af:resource type="javascript">
      function convertToUpperCase(evt){
        var field = evt.getCurrentTarget();
        var fieldVal= field .getSubmittedValue();
        field .setValue(fieldVal.toUpperCase());        
    }
    </af:resource>


 <af:inputText label="Label 1" id="it1">
                <af:clientListener method="convertToUpperCase" type="valueChange"/>
              </af:inputText>


3. You can create ViewRowImpl.java class with accessors and use toUpperCase() of String class

    public void setFirstName(String value) {
        setAttributeInternal(FIRSTNAME, value.toUpperCase());
    }


Thanks :) Happy Learning :)
