How to execute component method if it is already used for fill datagrid

[Former Member]

Hello !

Could anybody help me.

I have appliction where datagrid has been filled using method of component controller e.g. companyComponent.executeFilterCompany();

In view for edit data I made button, if I press this button I have to call this method companyComponent.executeFilterCompany(); to make some checks based on my own input parameters. When I call it then datagrid refreshes by new results, but this behaviour is wrong. I have only to receive result from webservice and make some my comparing and actions. So I don't know how to call companyComponent.executeFilterCompany() twice in diferent places of application.

Thank you in advance.

Hello Sergey,

You create a new method where you execute web service (do not call other method again)

You can achieve all the steps by applying Service Controller Template on the component controller.

In Web Dynpro Explorer, right click on component controller, choose Template -> Apply, choose Service Controller & go through the wizard pages. This will create a new context structure for the chosen executable model class, write some initialization code in wdDoInit() method and create execute... method (name you give in last wizard page) with execution code. Now, your this new context will have resultset when you call this newly created execute method. Work on this context.

Kind Regards,

If gen_wdp is deleted, choose Reload from dc's context menu.

Hello Sergey,

What I get is that in this component method, you execute the webservice method, the results fills up the context, your datagrid is bound to this context hence gets filled up.

Now, you want to execute webservice for some other task also with diff parameters and your datagrid should not refresh.

I feel you will not able to call this component method as such, instead I would advise you to create a separate context for the same, a separate method where you execute webservice & let resultset fill this new context & then work on this context.

Kind Regards,

I tried to make new context, it is filterCompanyCheck to the same method as filterCompany.

http://haxt.narod.ru/projects/1.JPG

is it correctly to make it as on the picture ?

But in this case it will be necessary to call the same method for context filterCompanyCheck as for filterCompany, it will cause problem I described

companyComponent = wdThis.wdGetCompanyController();

companyComponent.executeFilterCompany();

Something I can't understand, Maybe somebody has some documentation about it or examples ?

[nikhil_bose]

Probably old filtering values may be passed to web service. In side companyComponent.executeFilterCompany() print input parameters.

My problem is: I have webservice method that is used to obtain data for datagrid, I want to use this method also for other task, but I don't know how to do it because call of this method refreshes context that connected with datagrid. Please suggest me how to make independent call of webservice ?

[Former Member]

Does anyone know it possible to call webservice method independently to context ? Overwise this webdynpro framework updates datagrid based on results of this method.
