Re: [Htmlunit-user] java.lang.ClassCastException: com.gargoylesoftware.htmlunit.TextPage cannot be cast to com.gargoylesoftware.htmlunit.html.HtmlPage

[Sreenadh VP <sre...@co...>]

Hi,

Thanks for your attention and response.

I have following code

WebRequest request = new WebRequest(new URL(Url));

HtmlPage   page = webClient.getPage(request);

HtmlButton elementTocick = (HtmlButton)page.getElementById("elementId");

    page = elementTocick.click(); // fails with
java.lang.ClassCastException: com.gargoylesoftware.htmlunit.TextPage cannot
be cast to com.gargoylesoftware.htmlunit.html.HtmlPage

Need to assign new page  after click to* page* reference of type HtmlPage,
how can do the the same? Please advice

Sreenadh
