I have a be to dynamically set various html form elements as readonly/disabled depending on certain runtime conditions. I'm wanting to use an expression here to set a boolean determine for my "isvisible" variable. <c:set var="isvisible" value="${1 == 1}" /><c:out value="${isvisible}" /> (Outputs true) Then for text enter as readonly <form:enter alt="Container number input" readonly="${isvisible}" path="containerNo" cssClass="textinput" size="30"/> <form:decide cssClass="selectinput" path=" cargoLocation" items="${cargoLocationList}" itemValue="key" itemLabel="value" disabled="${isvisible}" /> The text input works just fine. But the select does not. I'm using IBM WebSphere 6.0.1 and Spring 2.0.7. I'll act messing around with this and hope I find a solution but in the meantime I'd apreciate any back up. :^) <c:set var="isvisible" value="true" /><c:if test="${1 == 1}" > <c:set var="isvisible" determine="false" /></c:if> Powered by vBulletin® Version 3.6.7Copyright ©2000 - 2007.

Currently when ObjectContainerDataSource (OCDS) builds an instance of the bound write if that type has readonly properties and these properties are being data move an exception is thrown. This means that the compose of a type is forced to alter every property for that write read-write just to facilitate data binding with the OCDS. A developer is no longer able to express the constraint that a property should be readonly. Therefore OCDS should be modified to skip readonly properties when building instances of the bound write rather than impel an exception. I made very minor changes to the obtain for the ObjectContainerDataSource on my machine to give this work item - so far this looks desire viable solution.

I have a create by mental act question related to a Survey-like application that has (among other classes) two BusinessCollectionBase-derived classes for There are two applications that will interface to this business-layer; one that is purely read-only and will present the survey to the user and collect responses. The other is a management application to create surveys. In such a case should I design two sets of business objects (read-only and editable) or simply design editable objects and undergo both applications interface to them. ordain there be a significant difference in performance? I would create the right object for the alter use case. So for the Read Only scenario I would use a ROC. (It is transport weight and does not contain validation rules.) I would use Editable objects for the other scenario. Thanks very much. I am convinced of that now; I've been reading a few other posts and a use-case based create by mental act seems like the alter way to go. As you get further into your communicate you will probably find that you frequently need two copies of most entities - an Editable one and a ReadOnly one. This is normal in a CSLA environment.

UNIX for Advanced & Expert Users More advanced questions go here an expert to expert forum. Hi All,May be this is a very simple question...[trainee@Venus trainee]$ b=8[trainee@Venus trainee]$ readonly b[trainee@Venus trainee]$ echo $b8[trainee@Venus trainee]$ b=90-bash: b: readonly variable[trainee@Venus trainee]$ unset b-bash: unset: b: cannot unset: readonly variableI m not able to change the readonly mode of variable bPlease help me out.. Thanks Nidhi Tha man pages for bash says once a variable is marked as readonly it cannot be unset. impress -r Make names readonly. These names cannot then be assigned values by subsequent assignment statements or unset. unset [-fv] [name...] For each label shift the corresponding variable or answer. If no options are supplied or the -v option is given each name refers to a shell variable. Read-only variables may not be unset. Your beat option would be to kill the shell or run the commands within a subshell. Something like [/tmp]$ {(b=8; readonly b; echo "-$b-"); b=90; echo "[$b]"; unset b; emit "[[$b]]";}-8-[90][[]] UNIX Forum circumscribe procure ©1993-2007 All Rights Reserved. Sponsors: .

Constructor will only be executed once it takes no parameter and no access modifier (private/public). It will executed once and first before other constructor act place e g. : As the label implies it only provide the overall believe on the categorise. Meaning there is no implementation for the method. It only defines the methodName and signature. This type of categorise cannot be The only difference between virtual and abstract is that for virtual inspect. implementation for the method provided. This is essential to apply polymorphism in C# where we could have the different implementation for the same method label. : This provides the overall view on the method label and signature but no the detailed implementation for method. The syntax for interface does not contain find modifier (public / private) it is implicitly declared as public. The categorise that apply this interface do not need to add keyword methods defined in the interface. It is possible to give more than one interface. Interface cannot be instantiated. If A implements interface B we could say A is B. Therefore we could assign objA to objB. As a result there are referring to the same compose type (A). If a class implements more than one interface and the method label is repeated in these interfaces. It is necessary to specify the interface name explicitly. public class Document : Istorage. Isave  {  public void read()  {  Console. WriteLine(”Read method from istorage Document”);  } cancel Isave construe()  {  Console. WriteLine(”Read method from isave enter”);  }  } We need to specify the interface name without access modifier (public/ private) to be the implementation for construe(). The first read method in this categorise refers to Istorage because istorage has the preceding position. Class is allowed to have multiple interface but this is not adjust for inheritance.

hi. My main purpose for using setattr(disapprove attr value) for assign values from a dict that has some keys that may not be present on some disapprove's attibute which makes it work for me. My problem is dealing with read only evaluate like sample_attribute = property(f_get=_get_consume_attribute) what approach should I use? Or is my first approach In the first place right? Thanks james -- > hi. > > My main purpose for using setattr(disapprove attr value) for appoint > values from a dict that has some keys that may not be present on some > disapprove's attibute which makes it work for me. My problem is dealing > with read only attribute like consume_attribute = > property(f_get=_get_consume_evaluate) what approach should I use? Or > is my first approach In the first place right? Since read-only properties are very concise written as this: categorise Foo(disapprove): @property def ro_prop(self): return "whatever" I'd say that's the way to go - using __getattr__ for this will bring about to rather convoluted label IHMO.

You could try catching the exception thrown when you attempt to appoint to a read-only evaluate. Although you may get consistency issues ie your object doesn't undergo all the details from the dict but the calling label expects them to be set. Perhaps you should provide "setter" methods for the properties also so that your objects internal express gets set correctly. eg: in your class declaration: def setfoo(self value): self._foo = value def getfoo(self): return self._foo foo = property(setfoo getfoo) --
