i printing arbitrary number of identical forms on page using spring's <form:form tag, , need way distinguish between them, because form errors of 1 form printed on forms. currently identical forms bound same, single backing object. works fine, because user can submit 1 form @ time. i using spring validation validate form fields. when 1 of fields has error (let's 'name' empty) error message printed under 'name' field of forms. obviously, need way allow spring distinguish between forms, how? some example code: this spring webflow definition creates clientformbacking object client forms. , submits form post bindandvalidate method, calls validator. <webflow:var name="clientformbacking" class="com.example.clientformbacking"/> <webflow:view-state id="list" view="clients" model="clientformbacking"> <webflow:on-entry> <webflow:evaluate expression="contextparamete

unity3d - EveryPlay IsRecordingSupported is False on Android Nexus 5 -

everyplay.sharedinstance.isrecordingsupported() false on android devices - nexus 5 , 7. i still able record , post video on devices if ignore value. note: everyplay.sharedinstance.issupported() true should check everyplay.sharedinstance.isrecordingsupported() before showing everyplay recording/sharing option user - everyplay.sharedinstance.isrecordingsupported() ? due wide range of driver behaviour, hardware encoders, gpus , android version differences out there, everyplay sdk caches device specific settings online remote server until settings received, recording support automatically disabled. after receiving server response, recording support either enabled or continued disabled workaround devices known cause trouble. next time application started, settings applied cache upon startup without requiring network access in it's current form, there's chance of getting unsupported status everyplay.sharedinstance.isrecordingsupported() if method called

i have plane class holds n normal , q point on plane. have point p lies on plane. how go rounding p nearest unit on plane. snapping cursor 3d grid grid can rotating plane. image explain: red current point. green rounded point i'm trying get. probably easiest way achieve taking plane define rotated , shifted coordinate system. allows construct matrices transforming point in global coordinates plane coordinates , back. once have this, can transform point plane coordinates, perform rounding/projection in trivial manner, , convert world coordinates. of course, problem underspecified way pose question: transformation need has 6 degrees of freedom, plane equation yields 3 constraints. need add more information: location of origin within plane, , rotation of grid around plane normal. personally, start deriving plane description in parametric form: xvec = alpha*direction1 + beta*direction2 + x0 of course, such description contains 9 variables (three vectors), c

java - Extending the automatically generated JPA controller (Netbeans 7.x) -

-
netbeans 7.x offers possibility generate entities (pojos) existing relational database (ex: customerentity, orderentity, etc.) also, generates automatically controller each entity (ex: customerjpacontroller, orderjpacontroller, etc.). the generated controllers contains many ready-to-use methods (findall, create, delete, etc.). advantage using controllers' generator possibility recreate/update them once entity (or table) modified (adding new constraints, new fields, etc.). unlike "partial class" concept offered .net, not possible extend these controllers user-defined methods in separate classes. what suggest (in terms of best practices or design patterns) take advantage of these automatically generated controllers? i use generated controller classes in self-created dao classes.
