Hi Doke,

The best way to declare public/private variable is to declare it on global area

Declare it at the end of view where you can see this begin and end part

Inside (As shown below) it will treated as golobal variable, which can reuseable

Anywhere within your iview.

//@@begin others

public String mystr1 = "";

//@@end

It will solve your problem.

Hi,

Create a context attribute lets say of type String named "Mystr"

int the wdDoinit method populate this context attribute with the default value.

wdContext.currentContextElement().setMystr("0123");

access this attribute from your methods.

String val = wdContext.currentContextElement().getMystr();

Hi,

You can achieve this by declaring the line code -

---

String mystr1 = ""; in global section.

check out for the below mentioned section in your code and insert the declaration in it.

//@@begin others

//@@end
