Default value for viewParam

Nobody has claimed this yet.

What about allowing the definition of a default value for a view-parameter?

**Example**

Defining number of displayed items (pagination feature) as a view-parameter but still keeping default value within xhtml and not java bean.

Following example is a very clean approach provinding a default value.

```

```

Currently there are two workarounds which have no clean separation between markup and java code:

**Workaround 1**

Passing the default value to bean.

```

```
```
private int pageSize;

public void initPreRenderView(int pageSize)
{
if (this.pageSize == 0)
this.pageSize == pageSize;
}
```

**Workaround 2**

Hardcoding the default value in bean. But markup should be responsible and not bean.

```

```
```
private int pageSize = 10;
```

Start by tracing how the XHTML f:viewParam value is processed when the request omits pageSize. The change is complete when a declared default such as 10 is used without Java-bean initialization, while an explicitly supplied parameter still takes precedence.
