getter/setter for textfield component

[bogdan_cm <bo...@rbccm.com>]

Hi all, 
   I have a textfield component inside a loop. The value of the text
component is set like this:
  <t:textfield t:value="getValueForKey(for_value)"></t:textfield>

The entire loop is enclosed in a <form>. When i try to submit the form, I
get the following error:

An exception has occurred: Failure writing parameter 'value' of component
Index:textfield: Expression 'getValueForKey(for_value)' for class
com.example.tutorial.pages.Index is read-only


My Java class does contain a setter method:

	public String getValueForKey(String key) {
		return arUser.getValueForKey(key);
	}

	public void setValueForKey(String key) {
		System.out.println("DO NOTHING");
	}

The only funny thing i'm doing here is that the java class does not have a
property "per se", only getter and setter methods. 

Thanks very much, 
Bogdan.

Interesting. I just did not realize the class property will be assigned the
map keys one by one as I loop through them (the documentation clearly states
this ).  

Thanks for the reply, 
Bogdan.

You can't use 'getValueForKey(for_value)' in a template

Here is how I would do it

<t:loop source='keys' value='key'>
   <t:textfield t:value='value'/>
</t:loop>

private Map<String, String> something;

@Property
private String key;

public Set<String> getKeys(){
   //Somehow you have already loaded the map
   return something.keySet();//keys
}

public String getValue(){
   return something.get(key);
}

public void setValue(String value){
   something.put(key, value);
}

regards
Taha
