Auto increase the rows of Input Text

Question

JDev 11.1.1.5.0 BPM SOA
Need to automatically increase the number of rows of  an input text component according to the data. If the data is pretty large, display it in multiple rows or if it is small, display it in a single row.

Answer 1

You can try to put a EL on the rows attribute which points to a bean method where you calculate the number of rows you want to show:
    public Integer getRows() {
        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
        AttributeBinding attr = (AttributeBinding)bindings.getControlBinding("myString1");
        String str = (String)attr.getInputValue();
        if (str == null)
            return 1;
        int len = str.length();
        if (len <= 10) {
            return 2;
        } else if (len <= 20)
            return 3;
        else
            return 4;
and on the page:
              <af:inputText label="Label 3" id="it7"
                            value="#{bindings.myString1.inputValue}"
                            rows="#{Page1Bean.rows}" autoSubmit="true"/>
if the bean is registered under Page1Bean and the inputText vaule property is bound to "myString1".
