>          Issue Type: Bug
>          Components: codegen
>    Affects Versions: 1.3
>         Environment: Windows XP
>            Reporter: Dave Meier
>            Priority: Blocker

> Using:
> org.apache.axis2.wsdl.WSDL2C -f -uri aewebservicesaxis70.wsdl -o aewebservicesaxis70 -d adb -ss -sd
> Problem:
> In the serialize methods, the namespaces hashtable is being freed for many of my adb objects, but one object that is nested frees this hashtable, then returns and the calling serialize method then tries to use the freed table and crashes.
> Here's a code fragment showing the calling serialize method (adb_NameValue_serialize(...)):
>   if (!_NameValue->is_valid_setValueBy)
>   {
>     /* no need to complain for minoccurs=0 element */
>   }
>   else
>   {
>     start_input_str = (axis2_char_t*)AXIS2_MALLOC(env->allocator, sizeof(axis2_char_t) *
>       (4 + axutil_strlen(p_prefix) + 
>       axutil_strlen("setValueBy") + 
>       ADB_DEFAULT_DIGIT_LIMIT* 2)); 
>     end_input_str = (axis2_char_t*)AXIS2_MALLOC(env->allocator, sizeof(axis2_char_t) *
>       (5 + ADB_DEFAULT_DIGIT_LIMIT + axutil_strlen("setValueBy")));
>     /*
>     * parsing setValueBy element
>     */
>     sprintf(start_input_str, "<%s%ssetValueBy",
>       p_prefix?p_prefix:"",
>       (p_prefix && axutil_strcmp(p_prefix, ""))?":":""); 
>     start_input_str_len = axutil_strlen(start_input_str);
>     sprintf(end_input_str, "</%s%ssetValueBy>",
>       p_prefix?p_prefix:"",
>       (p_prefix && axutil_strcmp(p_prefix, ""))?":":"");
>     end_input_str_len = axutil_strlen(end_input_str);
>     if(!adb_Set_Value_By_is_particle())
>     {
>       axutil_stream_write(stream, env, start_input_str, start_input_str_len);
>     }
>     adb_Set_Value_By_serialize(_NameValue->property_setValueBy, 
>       env, current_node, parent_element,
>       adb_Set_Value_By_is_particle() || AXIS2_FALSE, namespaces, next_ns_index);  // THIS IS WHERE namespaces gets freed
>     if(!adb_Set_Value_By_is_particle())
>     {

>     }
>   } 
>   if(!(p_prefix = (axis2_char_t*)axutil_hash_get(namespaces, "urn:aewebservicesaxis70", AXIS2_HASH_KEY_STRING)))  // THIS IS WHERE it gets used again and crashes
> ...
> I will attach my wsdl file and the two adb files involved in the code above ( adb_NameValue.c which contains the above code and adb_Set_Value_By.c which contains the adb_Set_Value_By_serialize(...) method that frees the namespaces hashtable.
