jsf - After confirmation, navigate to first tab of wizard -

-

Too much, everything is said in the subject's title. What I need to achieve is that when I click on the tab of the last (confirmation) wizard and my button, after all, I want to return to the wizard's first tab. Of course, everything in the magician should be reset after that.

Well, that's not help. Currently I'm totally confused. I get this exception when I click on the button, but not in the server log, I only get in the browser:

An error occurred:

 The button looks like this:  
  & lt; p: commandButton ajax = "false" value = "service" Save = "# {Kuben. Svs service}" update = "growl" / & gt;    
 
 
 Interesting ...  
 Assume that your bean < Code> @ViewScoped  Then a simple page redirect on your wizard page URL should restore your wizard managed wan. If that does not work then you can add GET property  [url] - faces-redirect = true  on the URL.  
 to switch to it will not work if your managed bean  @ session-Scokd  Although expected data and state information from the previous wizard confirmation would still be the best solution ViewScoped and if it write a reset method of managed Bean is not possible, which may state the managed bean and clear data.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
