T5: client state problem
Hi
It seems that, on a form submit, T5 automatically redirect to a "GET"
url with client state encoded in the URL. This produces a bookmarkable
URL which is very nice. However, I am running into the following problem
where T5 generates an extremely long "t:state:client" parameter as the
following,
/viewquotes?t:state:client=H4sIAAAAAAAAAE2QPUsDQRCGJ18GYypFrAQLmzSbICQKV

My form only contains one text field that allows user to input a stock
symbol. This long parameter gets carried to all pages and ofter leads to
the following failure
An unexpected application exception has occurred.
Serialized client state was corrupted. This may indicate that too much
state is being stored, which can cause the encoded string to be
truncated by the client web browser.
Any idea why such a long state parameter? Why it gets attached to other
unrelated pages as well? How to avoid this? I am using 5.0.11-snapshot.
Thanks,
Xiaohong

Posted by "Zheng, Xiahong" <Xi...@FMR.COM>.
The form will retrieve stock quote for the symbol entered. The Quote
object is then set on the response page. The response page is using
client persistence strategy via the following meta annotation
@Meta("tapestry.persistence-strategy=client")
The quote object is declared as following
public class Quote implements Serializable
{
private String symbol;
private String price;
private String changeToday;
private String securityName;
/**
* @return Returns the changeToday.
*/
public String getChangeToday()
{
return changeToday;
}
/**
* @param changeToday The changeToday to set.
*/
public void setChangeToday(String changeToday)
{
this.changeToday = changeToday;
}
/**
* @return The stock price
*/
public String getPrice()
{
return price;
}
/**
* @param price The stock price
*/
public void setPrice(String price)
{
this.price = price;
}
/**
* @return The stock symbol
*/
public String getSymbol()
{
return symbol;
}
/**
* @param symbol The stock symbol
*/
public void setSymbol(String symbol)
{
this.symbol = symbol;
}
/**
* @return The security name
*/
public String getSecurityName()
{
return securityName;
}
/**
* @param securityName The security name
*/
public void setSecurityName(String securityName)
{
this.securityName = securityName;
}
}
Will one instance of such object be serialized into such a long string?
The retrieved quote contains the following exact content,
Symbol="MSFT"
securityName="MICROSOFT CORPORATION"
Price="27.5900"
changeToday="0.600"

I believe the wiki has code for a "client:form" persistent strategy
that persists data, but only inside <form> elements.
I would also be concerned at the amount of data here; perhaps an
entire StockSymbol entity (or whatever) is being serialized into the
form, rather than just the stock ticker id.
